Find the distance traveled by a particle with position (x, y) as t varies in the given time interval. x = 3 sin^2 (t), y = 3 cos^2 (t); 0 less than or equal to

Answers

Answer 1

From distance formula, the distance covered by a particle with position (x, y) as time, t is equals to the [tex] 18\sqrt{2}[/tex].

The distance d, traveled by the particle with position vector, r(t) = <x(t), y(t) > over the interval [a,b] is calculated by following

[tex]d = \int_{a}^{b} ( (\frac{dx}{dt})² +(\frac{dy}{dt})² )dt[/tex]. We have a particle with position value (x, y) as t varies in the time interval. The parametric equations are, x = 3 sin² (t), y = 3 cos²(t), on the

time interval [0,3π]. Now the derivative of above parametric equations with respect to time t are [tex]\frac{dx}{dt} = 6 sin(t)cos(t) [/tex] = 3 sin(2t)

[tex]\frac{dy}{dt} = -6 sin(t)cos(t) [/tex]

= - 3 sin(2t)

Therefore, the required distance travelled by particle in the interval [0,3π] is written as [tex]d = \int_{0}^{3π} \sqrt{( (3 sin(2t))² + (-3 sin(2t))²) dt} \\ [/tex]

[tex]= \int_{0}^{3π} \sqrt{ ( 9 sin²(2t) + 9sin²(2t))}dt \\ [/tex]

[tex]= \int_{0}^{3π} \sqrt{18sin²(2t)dt}[/tex]

[tex]= 3\sqrt{2}\int_{0}^{3π} |sin(2t)|dt[/tex]

[tex]= 3\sqrt{2}[ \int_{0}^{\frac{π}{2}} sin(2t)dt - \int_{\frac{π}{2}}^{π} sin(2t)dt + \int_{π}^{\frac{3π}{2}} sin(2t)dt - \int_{\frac{π}{2}}^{2π}sin(2t)dt + \int_{2π}^{\frac{5π}{2}}sin(2t)dt - \int_{\frac{5π}{2}}^{3π}sin(2t)dt \\ [/tex]

[tex]= 3\sqrt{2}([ \frac{cos(2t)}{2}]_{0}^{\frac{π}{2}} - [\frac{cos(2t)}{2}]_{\frac{π}{2}}^{π} + [\frac{cos(2t)}{2}]_{π}^{\frac{3π}{2}} - [\frac{cos(2t)}{2}]_{\frac{3π}{2}}^{2π} + [\frac{cos(2t)}{2}]_{2π}^{\frac{5π}{2} }- [ \frac{cos(2t)}{2}]_{\frac{5π}{2}}^{3π})\\ [/tex]

[tex]= 3\sqrt{2}([ \frac{1}{2} +{\frac{1}{2}] - [\frac{-1}{2}- \frac{1}{2}}] + [\frac{1}{2}+ \frac{1}{2}] - [\frac{-1}{2} - \frac{1}{2}] + [\frac{1}{2} + \frac{1}{2}]- [ \frac{-1}{2} - \frac{1}{2}])\\ [/tex]

[tex]= 3\sqrt{2}(6)[/tex] =[tex]= 18\sqrt{2}[/tex]

Hence, the required distance is [tex] 18\sqrt{2}[/tex].

Answers

The satellite should be insured for 98 months (rounded up to the nearest month) to be 96% confident that the microchip will last beyond the insurance date.

To answer this question, we need to find the number of months for which we can be 96% confident that the microchip will not malfunction. This means we want to find the value of x such that P(X > x) = 0.04, where X is the random variable representing the life expectancy of the microchip.

We know that X follows a normal distribution with mean μ = 92 months and standard deviation σ = 3.6 months. Therefore, we can standardize X to the standard normal distribution Z ~ N(0, 1) using the formula

Z = (X - μ) / σ

We can then rewrite the probability P(X > x) as

P(X > x) = P(Z > (x - μ) / σ)

1.75 = (x - 92) / 3.6

Solving for x, we get

x = 98 months

Answers

To find an expression for P(t), we can use the two given data points to create a system of equations. We can assume that the population is growing exponentially, which means that the population at time t is given by:

P(t) = a(b)^t

where a and b are constants that we need to determine.

Using the first data point, we have:

840,000 = a(b)^1

which simplifies to:

840,000 = ab

Using the second data point, we have:

882,000 = a(b)^2

We can solve for a in terms of b by dividing the second equation by the first equation:

882,000/840,000 = (a(b)^2)/(ab)

Simplifying, we get:

1.05 = b

Substituting this value of b into the first equation, we get:

840,000 = a(1.05)

Solving for a, we get:

a = 800,000

Therefore, the expression for P(t) is:

P(t) = 800,000(1.05)^t

This means that the city's population t years from now can be calculated by multiplying the initial population of 800,000 by 1.05 raised to the power of t.

When Gina first started working for a pro football player, he had 4,125 followers and she was able to increase his followers by 9% per month. How long would it take the football player to double his current online following of 105,326? Round answer to two decimal places

Answers

It would take about 8.59 months for the football player to double his current following, assuming that his follower count continues to increase at a rate of 9% per month.

To find out how long it would take for the football player to double his current online following of 105,326, we need to find the distance from his starting point to the doubling point. In other words, we need to find out how many followers he needs to gain in order to have 2 times his current following.

To do this, we can use the formula for exponential growth:

A = P(1 + r)ⁿ

where A is the final amount, P is the initial amount, r is the rate of growth (in decimal form), and t is the time (in months).

In this case, we want to find t, the time it would take for the football player to double his current following. So we can rewrite the formula as:

2P = P(1 + 0.09)ⁿ

Simplifying this equation, we can divide both sides by P:

2 = (1 + 0.09)ⁿ

Taking the natural logarithm of both sides, we get:

ln(2) = t ln(1 + 0.09)

Solving for t, we divide both sides by ln(1 + 0.09):

t = ln(2) / ln(1 + 0.09)

Using a calculator, we get t ≈ 8.59 months.

Regularly depositing the same amount into a savings account can lead to a large rise in the account balance over time with the appropriate plan and dedication.

What is amount?

An undefined number or quantity of something is referred to as an amount and can be used in a variety of different settings. Any number, quantity, length of time, or amount of data can be referred to as an amount. Amount in terms of money refers to the total amount being paid or received. The quantity of physical items is the total number of those items. The length or duration of a work or event can be referred to as the amount in terms of time. The entire quantity of data points or pieces of information is referred to as the amount in terms of data.

Here in the question:

Month | Amount Deposited | Account Balance

1           | 150                           | 150

2          | 150                           | 300

3          | 150                           | 450

4          | 150                           | 600

5          | 150                           | 750

As seen in the table above, after five months, a 150 initial deposit into a savings account can grow to a balance of 750 with monthly deposits of the same amount for the next four months. This demonstrates that consistent saving can have a considerable impact on a savings account's overall balance.

Since interest is calculated using the compounding principle, regular deposits can enhance the amount that can be earned over time. This indicates that interest may be accumulated on both the initial deposit and any prior interest in the account. So, by consistently contributing the same amount of money to a savings account, it is feasible to dramatically raise the account's overall balance.

In conclusion, it is clear that consistent contributions to a savings account can be an excellent strategy to build wealth. Regularly depositing the same amount into a savings account can lead to a large rise in the account balance over time with the appropriate plan and dedication.

Answers

Answer:

Step-by-step explanation:

Visualize the scenario for a second. If the ladder is leaning against the wall, we can assume that it is the hypothenuse of the triangle that is forming here. The angle of elevation in this scenario is the angle formed by the ladder and ground.

Next, recall each trig function and determine which best belongs. We have the hypothenuse and we need the side opposite the angle. Therefore, we use sine. (probably using a calculator for trig questions)

Therefore, we can now set up our equation and solve. (x is the height of the wall)

sin 56 = [tex]\frac{x}{12}[/tex]         Initial equation

12 sin 56 = x     Multiply each side by 12 so that we get x by itself.

Therefore, the answer is about 9.9 inches. (If you got something different, make sure that your calculator is in degrees and not radians! Some calculators abbreviate it as DEG and RAD respectively.)

at how many points on the interval is the line tangent to parallel to the secant line connecting the function endpoints?

Answers

The line tangent to f(x) = x + sin(x) is parallel to the secant line connecting the endpoints at x = π on the interval [-2π, 2π].

Let's begin by finding the slope of the secant line connecting the endpoints of the function. The endpoints of the function on the interval [-2π, 2π] are (-2π, -2π + sin(-2π)) and (2π, 2π + sin(2π)), which evaluate to (-2π, 0) and (2π, 0), respectively.

The slope of the secant line is

m = (0 - 0)/(2π - (-2π)) = 0

Since we want the tangent line to be parallel to the secant line, the slope of the tangent line should also be 0. We can find the equation of the tangent line using the point-slope form

y - (x + sin(x)) = 0

y = x + sin(x)

To find the points on the interval where the tangent line is parallel to the secant line, we need to find the values of x where the derivative of f(x) is equal to 0 (i.e., where the slope of the tangent line is 0). The derivative of f(x) is

f'(x) = 1 + cos(x)

Setting this equal to 0 and solving for x, we get

If you know the length of the short leg of a 30-60-90 triangle, how do you find the length of the other, longer leg?

Answers

The length of the longer leg of this 30-60-90 triangle is 6.93 units.

In a 30-60-90 triangle, the length of the shorter leg is opposite to the 30-degree angle. The longer leg is opposite to the 60-degree angle, and the hypotenuse is opposite to the 90-degree angle.

The ratio of the sides in a 30-60-90 triangle is always the same. The length of the shorter leg is half of the length of the hypotenuse. The longer leg is the square root of three times the length of the shorter leg.

Let's use this information to solve a problem. Suppose you have a 30-60-90 triangle with a shorter leg of length 4 units. We can use the ratio to find the length of the longer leg.

The length of the hypotenuse is twice the length of the shorter leg, which is 2 times 4 units = 8 units.

The longer leg is the square root of three times the length of the shorter leg, which is the square root of three times 4 units = 6.93 units.

Draw a coordinate plane. Plot the points: A(3, 4), B(2, 2), C(5, 8), D(7, 12), and E(9, 14). All but one of the points are on the same line. Which one is not?

Answers

The point that is not on the same line as the others is E(9, 14).

How to find the point ?

The point that is not on the same line as the others would not have the same slope as the others.

Slope between A ( 3, 4) and B (2, 2):

= (4 - 2) / (3 - 2) = 2 / 1

= 2

Slope between B (2 , 2) and C (5, 8):

= ( 8 - 2 ) / (5 - 2)

= 6 / 3

= 2

Slope between C ( 5, 8) and D(7, 12):

= (12 - 8) / (7 - 5)

= 4 / 2

= 2

Slope between D ( 7, 12) and E ( 9, 14):

= ( 14 - 12) / (9 - 7)

= 2 / 2

= 1

We can therefore see that E ( 9, 14) is the odd one out and is not on the same line.

The mean and the standard deviation of the sample of 100 bank customer waiting times are x⎯⎯ = 5.33 and s = 2.207. Calculate a t-based 95 percent confidence interval for µ, the mean of all possible bank customer waiting times using the new system. Are we 95 percent confident that µ is less than 6 minutes?. Assume normality.

Answers

95% confidence that the population mean is less than 6 minutes since the upper limit of the confidence interval is below 6 minutes.

95% confidence that the population mean is within the range of 4.897 to 5.763 minutes.

The t-based 95 percent confidence interval for the population mean:

CI =[tex]\bar x\pm t\alpha/2 \times (s/\sqrt n)[/tex]

[tex]\bar x[/tex]  is the sample mean, s is the sample standard deviation, n is the sample size, tα=/2 is the t-value corresponding to the desired level of confidence and (s/√n) is the standard error of the mean.

The sample size is 100, the sample mean is 5.33, and the sample standard deviation is 2.207, the standard error of the mean is:

s/√n

= 2.207/√100

= 0.221

The t-value corresponding to a 95% confidence level with 99 degrees of freedom (100 - 1), look it up in a t-distribution table or use a calculator.

The t-value is approximately 1.984.

The 95% confidence interval for the population mean is:

CI = 5.33 ± 1.984 × 0.221

= [4.897, 5.763]

six integers have a range of 13. The integers are 5,9,7,12,3,x. Find the value of x

Answers

Thus, for the given range of data of six integers the value of x is found as: x = 16.

Explain about the range of data:

The difference here between maximum and smallest values in a data set is known as the range. Employing the exact same units as the data, it measures variability. More variability is shown by larger values.

Take the highest value and deduct the lowest value from it to determine the range in statistics.

A data set's range

Range is equal to the highest and lowest values.

Since the formula subtracts any smaller value from the larger one, it is impossible for it to be negative.

Given data:

six integers:  5,9,7,12,3,x.

Range = 13

The formula for the range ;

Range  = maximum value - minimum value

x - 3 = 13

x = 13 + 3

x = 16

Thus, for the given range of the data of six integers the value of x is found as: x = 16.

The length of a rectangle is
double its width and the area of
the rectangle is 288 cm². What is
the perimeter of the rectangle?

Answers

The perimeter of the rectangle is 72 cm.

what you mean by perimeter?

Perimeter is the total distance around the boundary of a two-dimensional shape. It is the sum of the lengths of all sides or edges of the shape.

The perimeter is usually measured in units such as centimeters (cm), meters (m), feet (ft), or inches (in), depending on the unit of measurement used for the sides or edges.

Let's start by assigning variables to the length and width of the rectangle.

Let x be the width of the rectangle in cm.

Then, the length of the rectangle is double the width, which is 2x cm.

We know that the area of the rectangle is 288 cm², so we can set up an equation:

Area = Length x Width

288 = 2x * x

Simplifying the equation, we get:

288 = 2x²

Dividing both sides by 2, we get:

144 = x²

Taking the square root of both sides, we get:

x = ± 12

Since x cannot be negative (as it represents a length), we take x = 12 cm as the width of the rectangle.

The length of the rectangle is 2x, which is 24 cm.

Now we can find the perimeter of the rectangle, which is given by the formula:

Perimeter = 2(Length + Width)

Substituting the values we found, we get:

Perimeter = 2(24 + 12) = 72 cm

Therefore, the perimeter of the rectangle is 72 cm.
