What is the explicit formula represented by this graph (4,9) (3,7) (2,5) (1,3)

Answers

Answer 1

Answer:

y = 2x + 1

Step-by-step explanation:

To find the explicit formula represented by the given points, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.

First, let's find the slope using any two points from the given points:

Slope = (change in y) / (change in x) = (7-9)/(3-4) = -2/-1 = 2

Now we have the slope (m = 2). We can use any of the points and the slope to find the y-intercept (b).

Using the point (4,9):

y = mx + b

9 = 2(4) + b

9 = 8 + b

b = 1

Therefore, the explicit formula represented by the graph is:

y = 2x + 1

Hope this helps!

The probability value for P(B) is obtained to be, Option (c) : 0.83.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

We can use the formula: P(A È B) = P(A) + P(B) - P(A Ç B) to find P(B).

Rearranging the terms, we get -

P(B) = P(A È B) - P(A) + P(A Ç B)

Substituting the given values, we get -

P(B) = 0.72 - 0.55 + 0.66

P(B) = 0.83

The probability of an event A occurring is denoted by P(A) and is a number between 0 and 1, inclusive.

If A and B are two events, then P(A È B) denotes the probability that at least one of A or B occurs.

P(A Ç B) denotes the probability that both A and B occur simultaneously.

The formula used to find P(B) in terms of P(A), P(A È B), and P(A Ç B) is known as the addition rule of probability.

Therefore, the answer is 0.83.

The amount of photosynthesis that takes place in a certain plant depends on the intensity of light x according to the equationf(x) = 175x2 − 40x3.(a) Find the rate of change of photosynthesis with respect to the intensity of light.f'(x)=?(b) What is the rate of change when x = 1? When x = 3?How fast is the rate found in part (a) changing when x = 1? When x = 3?

Answers

The rate of change of photosynthesis with respect to intensity of light is 230 when x = 1. The rate found in part (a) is decreasing at a rate of 470 when x = 3. The rate of change of photosynthesis with respect to the intensity of light is 230 when x = 1 and -2190 when x = 3.


(a) To find the rate of change of photosynthesis with respect to the intensity of light, we need to take the derivative of the equation f(x) = 175x^2 - 40x^3 with respect to x.

f'(x) = 350x - 120x^2

(b) To find the rate of change when x = 1, we substitute x = 1 into the derivative equation:

f'(1) = 350(1) - 120(1)^2 = 230


To find the rate of change when x = 3, we substitute x = 3 into the derivative equation:

f'(3) = 350(3) - 120(3)^2 = -630

Therefore, the rate of change of photosynthesis with respect to intensity of light is -630 when x = 3.

To find how fast the rate found in part (a) is changing when x = 1, we need to take the second derivative of the equation:

f''(x) = 350 - 240x

Then we substitute x = 1 into the second derivative equation:

f''(1) = 350 - 240(1) = 110

Therefore, the rate found in part (a) is increasing at a rate of 110 when x = 1.

To find how fast the rate found in part (a) is changing when x = 3, we also need to take the second derivative of the equation:

f''(x) = 350 - 240x

Then we substitute x = 3 into the second derivative equation:

f''(3) = 350 - 240(3) = -470


(a) To find the rate of change of photosynthesis with respect to the intensity of light, we need to find the derivative of the given function f(x) = 175x^2 - 40x^3.

f'(x) = d/dx (175x^2 - 40x^3) = 350x - 120x^2

(b) To find the rate of change when x = 1 and x = 3, simply plug these values into the derivative:

f'(1) = 350(1) - 120(1^2) = 350 - 120 = 230
f'(3) = 350(3) - 120(3^2) = 1050 - 3240 = -2190

suppose v1, v2, v3 is an orthogonal set of vectors in r5 let w be a vector in span (v1,v2,v3) such that (v1,v1) = 35, (v2,v2) = 334, (v3,v3) = 1
(w1,v1) = 175, (w2,v2) = -1670, (w3,v3) =-1
then w = ______ v1 + ___ v2 + _____ v3.

Answers

The vector w can be expressed as:
w = 5v1 - 5v2 - v3

Given the orthogonal set of vectors v1, v2, and v3 in R5, and the vector w in the span of these vectors, you have provided the following information:

- (v1,v1) = 35
- (v2,v2) = 334
- (v3,v3) = 1
- (w,v1) = 175
- (w,v2) = -1670
- (w,v3) = -1

To find w in terms of v1, v2, and v3, use the following formula for orthogonal projections:

w = (w,v1)/||(v1)||^2 * v1 + (w,v2)/||(v2)||^2 * v2 + (w,v3)/||(v3)||^2 * v3

Since (v1,v1) = 35, ||(v1)||^2 = 35.
Since (v2,v2) = 334, ||(v2)||^2 = 334.
Since (v3,v3) = 1, ||(v3)||^2 = 1.

Substitute the given values:

w = (175/35) * v1 + (-1670/334) * v2 + (-1/1) * v3

Simplify the coefficients:

w = 5 * v1 - 5 * v2 - v3

So, the vector w can be expressed as:

w = 5v1 - 5v2 - v3

assume that the mean height for men in the u.s. is 5’8"" with a standard deviation of 6"". how tall would a man have to be to have a z score of 2?

Answers

To answer this question, we can use the formula: z = (x - mean) / standard deviation

We know that the mean height for men in the U.S. is 5'8" with a standard deviation of 6". We also know that we want to find the height (x) that corresponds to a z score of 2.

Rearranging the formula, we get:
x = z * standard deviation + mean

Plugging in the values, we get:
x = 2 * 6 + 5'8"

Simplifying, we get:
x = 12" + 5'8"

Converting to feet and inches, we get:
x = 6'8"

Therefore, a man would have to be 6'8" tall to have a z score of 2, assuming a mean height for men in the U.S. of 5'8" with a standard deviation of 6".

What is equation of line?

A plane's equation is a linear expression made up of the constants a, b, c, and d as well as the variables x, y, and z. The direction numbers of a vector perpendicular to the plane are represented by the coefficients a, b, and c. The constant d can be thought of as the distance along the normal vector of the plane from the origin. The formula a(x1, y1, z1) = 0 can be used to get the equation of a plane, where (x1, y1, z1) is a specified point in the plane.

The acute angle between a line and a plane is given by:

cos(theta) = |n . d| / (|n| |d|)

where n is the normal vector to the plane, d is the direction vector of the line, and |.| denotes the magnitude.

From the equation of the plane, we can read off the normal vector n as (2, 1, 2).

From the vector equation of the line, we can read off the direction vector d as (-2, p, 0).

Substituting these values into the formula for the cosine of the acute angle, we get:

cos(30°) = |(2, 1, 2) . (-2, p, 0)| / (|(2, 1, 2)| |(-2, p, 0)|)

Simplifying and solving for p, we get:

cos(30°) = |(2, 1, 2) . (-2, p, 0)| / (|(2, 1, 2)| |(-2, p, 0)|)

1/2 = |-4 + 2p| / (√9 |p² + 4|)

Squaring both sides and simplifying, we get:

4(p² + 4) = 4(p² - 2p + 1)

4p² + 16 = 4p² - 8p + 4

8p = -12

p = -3/2

Therefore, the possible value of p is -3/2.

Answers

The equation y² - x⁵ = -7 at x = 2 and y = 5, the value of dy/dx is 8.

To find dy/dx for the equation y² - x⁵ = -7 at x = 2, y = 5, follow these steps:

1. Differentiate both sides of the equation with respect to x using implicit differentiation.

Differentiating y² with respect to x, we get 2y(dy/dx).
Differentiating -x⁵ with respect to x, we get -5x⁴.

So, we have: 2y(dy/dx) - 5x⁴ = 0.

2. Plug in the given values of x and y into the differentiated equation.

Substitute x = 2 and y = 5: 2(5)(dy/dx) - 5(2⁴) = 0.

3. Solve for dy/dx.

First, simplify the equation: 10(dy/dx) - 80 = 0.

Next, add 80 to both sides: 10(dy/dx) = 80.

Finally, divide both sides by 10 to get: dy/dx = 8.

So, for the equation y² - x⁵ = -7 at x = 2 and y = 5, the value of dy/dx is 8.

Answers

The trigonometric identity for this problem is proven, as tan(x)/csc(x) = 1/cos(x) - 1/sec(x).

How to simplify the trigonometric expression?

The trigonometric expression for this problem is defined as follows:

tan(x)/csc(x).

The definitions for the tangent and for the cossecant are given as follows:

tan(x) = sin(x)/cos(x).csc(x) = 1/sin(x).

When two fractions are divided, we multiply the numerator by the inverse of the denominator, hence:

tan(x)/csc(x) = sin(x)/cos(x) x sin(x) = sin²(x)/cos(x).

The sine squared can be given as follows:

sin²(x) = 1 - cos²(x).

Hence the simplified expression is given as follows:

(1 - cos²(x))/cos(x) = 1/cos(x) - cos(x).

The secant is one divided by the cosine, hence:

1/sec(x) = 1/1/cos(x) = cos(x).

Thus we can prove the identity, as:

tan(x)/csc(x) = 1/cos(x) - 1/sec(x).

Answers

Without more information, we cannot provide a more specific answer.

Without a diagram or more information about the plate and the forces acting on it, it is difficult to give a definitive answer to this question. However, we can make some general observations about the forces involved.

The ball-and-socket joint at a allows the plate to rotate freely around that point, while the roller point at b allows the plate to move horizontally without resistance. The cable at c is likely providing some sort of tension or support to the plate.

Assuming that the plate is in equilibrium, the sum of the forces acting on it must be zero. The force at point Bz would be the reaction force of the roller point at b. This force would be perpendicular to the surface of the roller and would depend on the weight of the plate and any other forces acting on it.

If we knew the weight of the plate and the angle at which the cable at c is pulling, we could use trigonometry and the principles of statics to calculate the magnitude and direction of the force at Bz. However, without more information, we cannot provide a more specific answer.

One number is 7 less than 3 times the second number. Their sum is 29 Find the numbers. Let the second number be x

Answers

Answer:

9 and 20

Step-by-step explanation:

From this problem we know that:

y=3x-7 (the first number is 7 less than 3 times the second number)

y+x=29 (their sum is 29)

We can use substitution to solve for x:

y+x=29

(3x-7)+x=29 (substituting y=3x-7)

4x-7=29

4x=36

x=9

Now that we know x=9, we can plug it back into one of the equations to solve for y:

y=3x-7

y=3(9)-7

y=20

Therefore, the two numbers are 9 and 20.

Answer:

x= 20;

y= 9.

Step-by-step explanation:

1. Name the variables.

Let the "first number" be "x";

Let the "second number" be "y".

2. Form the equations based on the statements.

       a) First statement.

       "One number is 7 less than 3 times the second number." Therefore:

       [tex]\sf x=3y-7[/tex]

       b) Second statement.

       "Their sum is 29." Therefore:

       [tex]\sf x+y=29[/tex]

3. Solve one of the equation for one of the variables.

Let's solve the second equation for "y":

[tex]\sf x+y=29\\ \\y=29-x\\ \\y=-x+29[/tex]

4. Use the calculated value of "y" to substitute in the first equation.

[tex]\sf \left \{ {{\sf x=3y-7} \atop {y=-x+29}} \right.[/tex]

[tex]\sf x=3(-x+29)-7[/tex]

Now, using the distributive property of multiplication, rewrite (check the attached image).

[tex]\sf x=[(3)(-x)+(3)(29)]-7\\ \\x=[-3x+87]-7\\ \\x=-3x+80[/tex]

Now, solve for "x".

[tex]\sf x+3x=-3x+80+3x\\ \\4x=80\\ \\\dfrac{4x}{4} =\dfrac{80}{4} \\ \\x=20[/tex]

5. Use any of the 2 equations to find the value of "y" from the calculated value of "x".

[tex]\sf y=-x+29\\ \\y=-(20)+29\\ \\y=9[/tex]

6. Verify the answer through evaluating with the statements.

[tex]\left \{ {{x=20} \atop {y=9}} \right.[/tex]

Does the sum of both numbers equal 29?

[tex]\sf 20+9=29\\ \\29=29[/tex]

Yes!

b. Express Joe's capital loss as a percent, rounded to the nearest percent.

Answers

Joe's capital loss is $1,392.

Rounding to the nearest percent, we get that Joe's capital loss was 32%.

What is  capital loss?

Capital loss is the difference between the purchase price and the selling price of an asset when the selling price is lower than the purchase price. It represents the loss incurred by the investor or trader due to the decrease in the value of the asset. Capital loss can be realized or unrealized.

a. Joe's capital loss is the difference between the selling price and the purchase price of the shares.

Purchase price = 200 shares * $22.07 per share = $4,414

Selling price = 200 shares * $15.11 per share = $3,022

Capital loss = Purchase price - Selling price

Capital loss = $4,414 - $3,022

Capital loss = $1,392

Therefore, Joe's capital loss is $1,392.

b. To express Joe's capital loss as a percent, we need to divide the capital loss by the purchase price and then multiply by 100.

Capital loss percent = (Capital loss / Purchase price) * 100

Capital loss percent = ($1,392 / $4,414) * 100

Capital loss percent = 31.51%

Rounding to the nearest percent, we get that Joe's capital loss was 32%.

consider rolling a pair of 4-sided fair dice where the two outcomes are x and y. define a new random variable z=xy. what is the probability that z is divisible by 2?

Answers

The probability that z is divisible by 2 is 12/16, which simplifies to 3/4 or 0.75.

To calculate the probability that z = xy is divisible by 2, we will first analyze the possible outcomes of rolling the pair of 4-sided fair dice. Since each die has 4 sides, there are a total of 4x4 = 16 possible outcomes.

We are interested in the cases where z = xy is divisible by 2, meaning that either x or y (or both) are even numbers. On a 4-sided die, half of the outcomes (2 sides) are even numbers, specifically 2 and 4.

There are three possible scenarios for z to be divisible by 2:
1. x is even and y is odd.
2. x is odd and y is even.
3. x and y are both even.

For scenario 1, there are 2 even outcomes for x and 2 odd outcomes for y, resulting in 2x2 = 4 possibilities.
For scenario 2, there are 2 odd outcomes for x and 2 even outcomes for y, also resulting in 2x2 = 4 possibilities.
For scenario 3, there are 2 even outcomes for both x and y, resulting in 2x2 = 4 possibilities.

The probability that z is divisible by 2 is 12/16, which simplifies to 3/4 or 0.75.

To calculate the probability that z = xy is divisible by 2, we will first analyze the possible outcomes of rolling the pair of 4-sided fair dice. Since each die has 4 sides, there are a total of 4x4 = 16 possible outcomes.

We are interested in the cases where z = xy is divisible by 2, meaning that either x or y (or both) are even numbers. On a 4-sided die, half of the outcomes (2 sides) are even numbers, specifically 2 and 4.

There are three possible scenarios for z to be divisible by 2:
1. x is even and y is odd.
2. x is odd and y is even.
3. x and y are both even.

For scenario 1, there are 2 even outcomes for x and 2 odd outcomes for y, resulting in 2x2 = 4 possibilities.
For scenario 2, there are 2 odd outcomes for x and 2 even outcomes for y, also resulting in 2x2 = 4 possibilities.
For scenario 3, there are 2 even outcomes for both x and y, resulting in 2x2 = 4 possibilities.

In total, there are 4+4+4 = 12 possible outcomes where z is divisible by 2. Thus, the probability that z is divisible by 2 is 12/16, which simplifies to 3/4 or 0.75.

find the radius of convergence, r, of the series. [infinity] n2xn 7 · 14 · 21 · ⋯ · (7n) n = 1 r = find the interval, i, of convergence of the series. (enter your answer using interval notation.) i =

Answers

The series converges for all x, the interval of convergence is (-∞, ∞) (i = (-∞, ∞)).

To find the radius of convergence, we can use the ratio test:

lim n→∞ |(n+1)2xn+1|/|n2xn| = lim n→∞ |(n+1)2/ n2| = lim n→∞ (n+1)2/ n2 = 1

Since the limit is 1, the ratio test is inconclusive, so we need to use another method. Notice that the series can be written as:

7n (7n+1) (7n+2) … (7n+6)

Using the factorial notation, we can rewrite this as:

7n (7n+6)! / (7n-1)!

Applying the ratio test again, we get:

lim n→∞ |(7n+1)(7n+2)…(7n+6)| / |(7n-1)(7n-2)…(7n-7)|

= lim n→∞ (7n+1)/7n * (7n+2)/(7n+1) * … * (7n+6)/(7n+5) * (7n+6)/(7n-6) * … * (7n+1)/(7n-1)

= lim n→∞ (7n+6)/(7n-6) = 1

Therefore, the series converges for all x, and the radius of convergence is infinity (r = ∞).

Answers

congruence means, the figures are a duplicate or an exact twin of the other, that is angles as well as sides are the same, well, clearly ABC is larger, so they're not congruent.

That said, we could have a figure with same angles, and another with the same angles, but their side are not restricted due to the angle, the sides can easily extend or shrink, whilst the angles are being retained all along, and thus the figures being similiar, but never congruent.

A bag has 7 blue and 4 green m&m's. If two m&m's are randomly selecte one after the other, what is the probability that they both are green? a. With Replacement.

Answers

The probability that they both are green is 13.22%. If the selection is done with replacement, then the probability of selecting a green M&M on the first draw is 4/11 (since there are 4 green out of 11 total M&Ms).

The probability of selecting another green M&M on the second draw is also 4/11, since the first M&M is replaced before the second selection is made, so the number of green and blue M&Ms remains the same. Therefore, the probability of selecting two green M&Ms with replacement is the product of the probabilities of selecting a green M&M on the first and second draws:

P(two green with replacement) = P(green on first draw) * P(green on second draw)
= (4/11) * (4/11)
= 16/121
≈ 0.1322
or about 13.22%.

The box plot represents the number of tickets sold for a school dance.

Tickets Sold for A Dance

Numbers 7-32 are shown on the box plot. The line on the left sides length is on the number 8, while it ends on the right side on number 31. A full rectangle is shown, distributed into two parts. One part of the rectangle is 15 to 19. The other part is smaller, 19 to 21. The bottom of the box plot labeled number of tickets shown.

Which of the following is the appropriate measure of center for the data, and what is its value?

The mean is the best measure of center, and it equals 19.
The median is the best measure of center, and it equals 19.
The mean is the best measure of center, and it equals 6.
The median is the best measure of center, and it equals 6.

Answers

The appropriate measure of center for the data is The median is the best measure of center, and it equals 19.

What are mean and median?

In statistics, both the mean and the median are measures of central tendency, which describe where the center of a distribution of data is located.

The mean, also called the arithmetic mean, is calculated by adding up all the values in a dataset and dividing by the total number of values. It is often used when the data is normally distributed and does not have extreme outliers that could significantly affect the value. The mean is sensitive to extreme values because they can have a large impact on the overall average.

The median is the middle value in a dataset when the values are ordered from smallest to largest. If there is an even number of values, the median is the average of the two middle values. The median is often used when the data has outliers or is skewed, as it is not affected by extreme values in the same way as the mean.

Both measures have their advantages and disadvantages, and the choice between using mean or median as a measure of central tendency depends on the nature of the data and the research question being addressed.

Based on the given information, the box plot shows the distribution of the number of tickets sold for a school dance. The box represents the middle 50% of the data, with the bottom of the box indicating the 25th percentile and the top of the box indicating the 75th percentile. The line inside the box represents the median, which is the middle value when the data is arranged in order. The "whiskers" extending from the box indicate the range of the data outside of the middle 50%.

In this case, the box plot shows that the middle 50% of the data falls within the range of approximately 15 to 21 tickets sold. The median value, indicated by the line inside the box, falls within this range, and based on the given information, it is not possible to determine whether the mean value would be higher or lower than the median. Therefore, the appropriate measure of center for the data is the median, and its value is 19.

So, the appropriate measure of center for the data is The median is the best measure of center, and it equals 19.

A snowmobile manufacturer produces three models, the XJ6, the XJ7, and the XJ8. The final testing bay is available for 40 hours in any given production planning week.

For each snowmobile model, a certain amount of testing time is required. The XJ6 requires 1 hour of testing, the XJ7 requires 1.5 hours of testing, and the XJ8 requires 2 hours of testing. To determine how many of each model can be produced in a week, linear programming techniques. We need to set up an equation using the available testing time. Let x, y, and z be the number of XJ6, XJ7, and XJ8 models produced in a week, respectively. Then, we have the following equation:[tex]1x + 1.5y + 2z[/tex][tex]\leq 40[/tex]

This equation represents the constraint that the total testing time required by all the snowmobile models cannot exceed the available testing time of 40 hours. We can use linear programming techniques to find the optimal values of x, y, and z that maximize the company's profits or minimize its costs, subject to this constraint and any other constraints that may be relevant.

given the following information for sample sizes of two independent samples, determine the number of degrees of freedom for the pooled t-test. n1 = 26, n2 = 15

Answers

The number of degrees of freedom for the pooled t-test for these two independent samples with n1 = 26 and n2 = 15 is 36.

How to determine the number of degrees of freedom for the pooled t-test?

We first need to calculate the degrees of freedom for each individual sample. The formula for degrees of freedom for an independent sample t-test is (n1-1) + (n2-1), which gives us:

(26-1) + (15-1) = 24 + 14 = 38

Next, we need to calculate the pooled degrees of freedom, which is simply the sum of the degrees of freedom for each sample minus the number of groups being compared (in this case, 2). So the formula is:

(df1 + df2) - k = (24 + 14) - 2 = 36

Therefore, the number of degrees of freedom for the pooled t-test for these two independent samples with n1 = 26 and n2 = 15 is 36.

The histogram of the distribution of the variable would have one peak and a long tail to the rightD. The histogram of the distribution of the variable would depend on the values of the data.E. There is insufficient information to determine the shape of the histogram of the distribution of the variable.

Answers

A. The histogram of the distribution of the variable would be roughly bell shaped.

If a variable is approximately normally distributed, its histogram will have a bell shape. This means that the majority of the data points will be clustered around the mean, with fewer and fewer data points as you move further away from the mean. The bell shape is symmetrical, which means that the left and right halves of the histogram will be mirror images of each other. The standard deviation of the data will determine how spread out the bell shape is.

The bell-shaped curve is commonly referred to as the normal distribution or Gaussian distribution. This distribution is widely used in statistics because many natural phenomena follow this pattern. For example, the heights of a population, the weights of a population, and the IQ scores of a population all tend to follow a normal distribution. This distribution is important because it allows us to make predictions and draw conclusions about a population based on a sample of data.

Your friend agrees to loan you $200 with an interest rate of 3%. what is the total amount paid back after one year. use the simple interest formula to find.

Answers

We will have to pay back $206 after one year for the loan of $200 with a 3% interest rate.

Explain interest rate

The interest rate is the amount of money charged by a lender to a borrower for the use of funds or the return earned on an investment. It is usually expressed as a percentage of the principal amount and is paid or earned annually. Interest rates are influenced by various factors such as inflation, economic conditions, and government policies. Higher interest rates lead to increased borrowing costs and higher returns on investments, while lower interest rates encourage borrowing and spending but reduce returns. Interest rates play a crucial role in shaping the economy and financial markets.

According to the given information

The simple interest formula is:

Interest = Principal x Rate x Time

In this case:

Principal = $200Rate = 3% = 0.03 (expressed as a decimal)Time = 1 year

So, the interest charged on the loan after one year is:

Interest = $200 x 0.03 x 1 = $6

Therefore, the total amount paid back after one year will be:

Total amount = Principal + Interest = $200 + $6 = $206

The two parallel sides, given the perimeter of the trapezium, can be found to be 9 cm and 18 cm.

The two parallel sides of the second trapezium can be found to be 10 cm and 20 cm.

How to find the parallel sides ?

Let's denote the parallel sides of the trapezium MUST as TS (shorter side) and MU (longer side), and the non-parallel sides as MS and UT.

TS + 2 * TS + MS + UT = 48

3 x TS + MS + UT = 48

Since MS + UT = 21, we can substitute this into the above equation:

3 x TS + 21 = 48

Now, solve for TS:

3 x TS = 27

TS = 9 cm

Now, find MU using equation (3):

MU = 2 x TS = 2 x 9 = 18 cm

So, the two parallel sides are 9 cm and 18 cm.

Let's denote the parallel sides of the trapezium as a (shorter side) and b (longer side), and the height as h.

The area of a trapezium can be calculated using the formula:

Area = (1/2) x (a + b) x h

180 = (1/2) x (a + 2a) x 12

180 = 3a x 6

180 = 18a

a = 10 cm

Now, find b using equation (3):

b = 2 * a = 2 * 10 = 20 cm

So, the two parallel sides are 10 cm and 20 cm.
