Please Help. I Don't Quite Understand This. Approximate The Area Under The Function Between A And B Using

Answers

Answer 1

Using a right-hand sum with three intervals, the approximate area under the curve of the function f(x) = x³ between the limits of integration a=0 and b=3 is 36 square units.

What is function?

Numbers and their variants, equations and related structures, forms and their arrangements, and the places where they might be found are all topics covered in mathematics. The term "function" describes the relationship between a collection of inputs, each of which has a corresponding output.

To estimate the area under the curve of the function f(x) = x3 between the limits of integration a=0 and b=3, we must divide the interval [0, 3] into three subintervals of equal width.

Each subinterval's width, x, may be calculated as follows:

Δx = (b - a) / n = (3 - 0) / 3 = 1

So, the three subintervals are:

[0, 1], [1, 2], [2, 3]

To compute the right-hand total, we evaluate the function at each subinterval's right endpoint and multiply it by the breadth of the subinterval. Then we add these products together to calculate the area under the curve. The right-hand sum may be stated mathematically as follows:

RH = Δx * [f(1) + f(2) + f(3)]

where x represents the width of each subinterval, f(x) = x3 represents the function we are integrating, and f(i) represents the function's value at the right endpoint of the i-th subinterval.

RH = 1 * [f(1) + f(2) + f(3)]

= 1 * [(1³) + (2³) + (3³)]

= 1 * [1 + 8 + 27]

= 36

Using a right-hand sum with three intervals, the approximate area under the curve of the function f(x) = x³ between the limits of integration a=0 and b=3 is 36 square units.

Find the interquartile range of the given data set.
8.4, 7.1, 6.3, 6.8, 9.2, 7.3, 8.8, 7.9, 5.3, 8.2

Answers

Thus, the interquartile range of the given data set. are -

1st quartile (Q1) = 6.8 ; 2nd quartile (Q2) = 7.6 and 3rd quartile (Q3) = 8.4 .interquartile range = 1.60.

Explain about the interquartile range:

The interquartile range in descriptive statistics reveals the spread of your distribution's middle half.

Each distribution that is sorted from low to high is divided into four equal portions using quartiles. The third and second quartiles, or the centre half of your data set, are contained in the interquartile range (IQR).

The interquartile range provides the range of a middle half of a data set, whereas the range provides the spread of the entire data set.

Given data set:

8.4, 7.1, 6.3, 6.8, 9.2, 7.3, 8.8, 7.9, 5.3, 8.2

arrange the data set in ascending order:

5.3, 6.3, 6.8, 7.1, 7.3, 7.9, 8.2, 8.4, 8.8, 9.2

Total term = 10 (even)

2nd quartile (Q2) 50% quartile - (5th + 6th) /2 = (7.3 + 7.9) /2 = 7.6

Now:

1st quartile (Q1) 25% quartile - 3rd term = 6.8

3rd quartile (Q3) 75% - 8th term = 8.4

Thus, the  interquartile range of the given data set. are -

1st quartile (Q1) = 6.8 ; 2nd quartile (Q2) = 7.6 and 3rd quartile (Q3) = 8.4 .

interquartile range = maximum  - minimum

interquartile range = 8.4 - 6.8 = 1.60.

Given the function f(x) = x, what is the effect of f(x) - 8?

A. The new line is parallel to the original

B. The new line has a smaller rate of change

C. The x intercept decreases

C. The y intercept increases

Answers

If the function f(x) = x, the effect of f(x) - 8 is: is (D) The y intercept decreases.

What is the effect of f(x) - 8?

The function f(x) = x is a linear function with a slope of 1, which means that for every increase of 1 in the x-value, the y-value also increases by 1.

If we subtract 8 from the function, we get:

f(x) - 8 = x - 8

This is still a linear function with a slope of 1, but it has been shifted downwards by 8 units.

Therefore, the effect of f(x) - 8 is that the y-intercept decreases by 8 (since the y-intercept of f(x) is 0 and the y-intercept of f(x) - 8 is -8), while the slope remains the same.

So the correct answer is (D) The y intercept decreases.

Using the following set of data, calculate the lower quartile, the upper quartile, and the interquartile range.

20, 22, 25, 28, 29, 30, 32, 33, 34

Be sure to show your work for finding:

the lower quartile
the upper quartile
the interquartile range

Answers

Answer:

To find the lower and upper quartiles and the interquartile range, we first need to order the data from smallest to largest:

20, 22, 25, 28, 29, 30, 32, 33, 34

Next, we find the median (middle value) of the entire dataset:

Median = (29 + 30) / 2 = 29.5

This median value divides the data into two halves. We then find the median of the lower half of the data, which includes all values less than or equal to 29.5:

Lower half: 20, 22, 25, 28, 29

Median of lower half = (25 + 28) / 2 = 26.5

This value, 26.5, is the lower quartile (Q1).

Similarly, we find the median of the upper half of the data, which includes all values greater than or equal to 29.5:

Upper half: 30, 32, 33, 34

Median of upper half = (32 + 33) / 2 = 32.5

This value, 32.5, is the upper quartile (Q3).

Finally, we can calculate the interquartile range (IQR) as the difference between the upper and lower quartiles:

IQR = Q3 - Q1 = 32.5 - 26.5 = 6

Therefore, the lower quartile is 26.5, the upper quartile is 32.5, and the interquartile range is 6.

Solve the systems of equations shown below.

2x- 6y = -12
X + 2y = 14

Answers

To solve the system of equations:

2x - 6y = -12
x + 2y = 14

We can use the elimination method by multiplying the second equation by 2 so that the coefficient of x becomes the same as the coefficient of x in the first equation:

2x - 6y = -12
2x + 4y = 28

We can now subtract the first equation from the second equation to eliminate x:

2x + 4y - (2x - 6y) = 28 - (-12)

10y = 40

y = 4

Substituting y = 4 into the second equation, we get:

x + 2y = 14

x + 2(4) = 14

x + 8 = 14

x = 6

Therefore, the solution to the system of equations is x = 6 and y = 4.

The relationship between tickets earned and points earned in a game is

• 3 tickets earned for every 27 points earned
If the pattern continues, how many tickets are earned when 54 points are earned?
Show your work.

Answers

The total number of 6 tickets will be earned when 54 points are earned.

Given that the total number of tickets earned for 9 points was earned = 1 ticket

the tickets earned when every 18 points are earned = 2 tickets

the tickets earned when every 27 points are earned = 3 tickets

Let's divide the points by tickets to find out how many points are earned for each ticket.

9/1 = 18/2 = 27/3 = 9

This shows for every ticket 9 points are earned. So, to find out the no. of tickets for 54 points, we can divide the 54 by 9.

no. of tickets earned for 54 points = 54/9 = 6 tickets.

From the above analysis, we can conclude that the 6 tickets are earned for 54 points.

Composite shape formed by a rectangle and two semicircles. Each semicircle has a diameter of 15 feet and is aligned with the length of the rectangle. The rectangle has a width of 4 feet.

perimeter: about
ft

area: about
ft²

Answers

The answer of the given question based on the circle and rectangle is , the perimeter of the shape is approximately 83.8 feet, and its area is approximately 148.4 feet².

What is Perimeter?

Perimeter is a measurement of the distance around the edge of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape. The perimeter is often measured in units of length, such as centimeters, meters, or feet.

To find the perimeter and area of the composite shape formed by a rectangle and two semicircles, we can break it down into its individual components and then add them up.

First, let's find the perimeter. The shape consists of two semicircles, each with a diameter of 15 feet, and a rectangle with a width of 4 feet and a length equal to the diameter of the semicircles, which is 15 feet. The perimeter can be calculated as:

Perimeter = 2 × (semicircle circumference) + rectangle perimeter

The circumference of circle is by the formula 2πr, where r is the radius. Since each semicircle has a diameter of 15 feet, its radius is 7.5 feet. Therefore, the circumference of each semicircle is:

C = 2πr = 2π(7.5) = 15π feet

The perimeter of the rectangle is simply the sum of its four sides, which is:

P = 2(length + width) = 2(15 + 4) = 38 feet

Putting it all together, we have:

Perimeter = 2 × 15π + 38 ≈ 83.8 feet

Now let's find the area. The shape consists of two semicircles, each with a diameter of 15 feet, and a rectangle with a width of 4 feet and a length equal to the diameter of the semicircles, which is 15 feet. The area can be calculated as:

Area = (semicircle area) + rectangle area

The area of a circle is given by the formula πr². Since each semicircle has a diameter of 15 feet, its radius is 7.5 feet. Therefore, the area of each semicircle is:

A = (1/2)πr² = (1/2)π(7.5)² = 44.18 feet²

The area of the rectangle is simply its length multiplied by its width, which is:

A = length × width = 15 × 4 = 60 feet²

Putting it all together, we have:

Area = 2 × 44.18 + 60 = 148.4feet²

Therefore, the perimeter of the shape is approximately 83.8 feet, and its area is approximately 148.4 feet².

The mass of the tree trunk is about
kilograms.

Question 2

b. For each of the next 5 years, the trunk puts on a growth ring 4 millimeters thick. In the first year, the height increases by 0.2 meter. The tree produces the same amount of wood each year. What is the height of the trunk after 5 years?
The height of the trunk is about
meters after 5 years.

Answers

Answer:

 a.  1492 kg

  b.  20.8 m

Step-by-step explanation:

Given a tree is initially 20 m high and has a diameter of 0.5 m, you want the mass of the trunk if its density is 380 kg/m³. If it adds a growth ring of 4 mm per year and adds height of 0.2 m in the first year, you want the height of the tree after 5 years, assuming the same amount of wood is added each year.

a. Mass

The volume of the tree trunk is that of a cylinder. The formula is ...

  V = (π/4)d²h

  V = (π/4)(0.5 m)²(20 m) ≈ 3.9270 m³

The mass is the product of volume and density:

  M = Vρ

  M = (3.9270 m³)(380 kg/m³) ≈ 1492 kg

The mass of the tree trunk is about 1492 kg.

b. Height

In the first year, the diameter of the tree increases by 8 mm, and the height increases by 0.2 m,. This means the volume of the tree increases to ...

  V = (π/4)(0.508 m)²(20.2 m) ≈ 4.0942 m³

The volume increase is the same each year for 5 years, so after 5 years, the volume is ...

  3.9270 m³ + 5(4.0942 -3.9270) m³ ≈ 4.7630 m³

At that time, the diameter is about 0.540 m. Solving the volume equation for the height, we find it to be ...

  h = 4v/(π·d²)

  h = 4(4.7630 m³)/(π·(0.54 m)²) ≈ 20.797 m

The height of the trunk after 5 years is about 20.8 m.

__

Additional comment

We note that the wood added in the first year includes the cylindrical shell represented by the tree ring, and a cylindrical "plug" that is 0.2 m high and equivalent in diameter to the rest of the tree. This seems an odd way for the tree to grow, but may be a reasonable approximation to the actual growth.

The height, diameter, and growth are all given to 1 significant figure. Hence the 4- and 3-significant figures used in the answers may be unsupported by the precision of the given numbers. Keeping 2 significant figures, we might report the initial mass as 1500 kg, and the final height as 21 m.

The graph is drawn by a function formulated to have the correct height at the x-intercept: v(d, h) - (final volume) = 0.

What is distance ?

Distance is an object's total, aimless movement. Without regard to whether an object represents a starting or finishing point, distance can be defined as the total distance travelled. Distance is referred to as the breadth or height of the difference between two locations. It should be highlighted that the distance between each of the vantage points as well as the distance travelled from one to the other are not the same thing. The total length of a path connecting two locations counts as the distance travelled. Distance is the real distance that a body travels. It also goes by the name "path length." For instance, the length of the route for an object moving from point O to point P would be OP = 360 m.

given,

To find the distance between the points (1, 5) and (3, 8), we can use the distance formula:

distance = √[(x2 - x1)² + (y2 - y1)²]

Substituting the given values, we get:

distance = √[(3 - 1)² + (8 - 5)²]

distance = √[4 + 9]

distance = √13

The expression that can be used to find out the amount of time it would take Sal to finish the remaining homework is C. 4 / 9 x 3 / 5 .

How to find the expression ?

To find the expression that would show the time it would take for Sal to finish his homework, the formula would be:

= Proportion of questions remaining x Time taken to finish one question

Proportion of questions remaining:

= 1 - 5 / 9

= 4 / 9

Time taken to finish one question:

= 3 / 5 minutes

The expression is therefore:

4 / 9 x 3 / 5

r=−5sinθ+4θ
Which of the following types of symmetry is demonstrated in the equation above based on the three symmetry tests for polar equations?
θ=π/2
polar axis
pole
none

Answers

Answer: Correct answer is pie/2 or A

Step-by-step explanation:

r = -5sinθ + 4θ has symmetry with respect to the line θ = π/2.

To demonstrate this, we can apply the third symmetry test for polar equations:

Symmetry with respect to the line θ = π/2: Replace θ by π - θ and see if the equation remains the same. If it does, the equation has symmetry with respect to the line θ = π/2.

r = -5sin(π/2 - θ) + 4(π/2 - θ) = 5cosθ + 2π - 4θ

r = 5cosθ + 2π - 4θ is the same as the original equation, so there is symmetry with respect to the line θ = π/2.

Therefore, the correct answer is θ = π/2.

Using the functions, we can find the graphs for each function as follows:

Graph 3 is: g (x) = [tex]4^{x}[/tex]

Graph 4 is: h (x) = [tex]-4^{x}[/tex]

Graph 2 is: f (x) = [tex]-(\frac{1}{4})^{x}[/tex]

Graph 1 is: k (x) = [tex](\frac{1}{4})^{x}[/tex]

Define functions?

A function is a procedure or a relation that links each element of a non-empty set A, at least one element of another non-empty set B, to another element of the first non-empty set A. In mathematics, a relation f between two sets, A and B, is referred to as the function's domain and co-domain. For all values of a and b, f = (a,b)|

Based on elements like the domain and range of a function, as well as the function expression, the function y = f(x) is categorised into many categories of functions. The domain x value is referred to as input for the functions. The domain value can be a fraction, decimal, angle, integer, or decimal. The range is also represented by the y value or the f(x) value.

Graph 3 is: g (x) = [tex]4^{x}[/tex]

Graph 4 is: h (x) = [tex]-4^{x}[/tex]

Graph 2 is: f (x) = [tex]-(\frac{1}{4})^{x}[/tex]

Graph 1 is: k (x) = [tex](\frac{1}{4})^{x}[/tex]

Based on the intersecting chords, the calculated value of x on the circle is 11

Calculating the value of x in the circle

The given shape in the question is a circle

As a general rule, a circle is a shape with all points on its boundary equidistant from a central point called the center

In this case, the center is point W

The sum of angles on the circumference is 360

So, we have

17x - 20 + 75 + 2 * 59 = 360

Evaluating the like terms, we have

17x = 187

Divide by 17

x = 11

Hence. the value of x is 11

The piecewise function graphed is defined as follows:

C)

y = 1/2x + 2, x ≤ -1.y = 1/2x² - 1, x > -1.

What is a piecewise function?

A piecewise function is a function that is defined by multiple equations, each of which applies to a specific interval or set of inputs. The equations are pieced together to form a single function that describes the behavior of the function over its entire domain.

The intervals for this problem are given as follows:

x ≤ -1.x > 1.

For the first interval, we have a linear function with a slope of 1/2 and an intercept of 2, hence:

y = 1/2x + 2, x ≤ -1.

For the second interval, we have a quadratic function with a vertex of -1, hence:

y = 1/2x² - 1, x > -1.

r=7/8cosθ+2sinθ
Which of the following gives the Cartesian form of the equation above?
Select the correct answer below:


x2+y2=7/10
y=−1/4x+7/8
y=−4x+7/2
8x2+2y2=7

Answers

Answer: 8x^2 + 2y^2 = 7

Step-by-step explanation:

The equation R = 7/8cosθ + 2sinθ can be rewritten in terms of x and y using the conversions x = Rcosθ and y = Rsinθ.

Substituting R = 7/8cosθ + 2sinθ into these equations, we get:

x = (7/8)cosθ cosθ + 2sinθ cosθ

y = (7/8)cosθ sinθ + 2sinθ sinθ

Simplifying these expressions using trigonometric identities, we get:

x = (7/8)cos^2θ + (4/8)sin2θ

y = (7/8)sinθ cosθ + (4/8)sin2θ

Multiplying both sides of the x equation by 8/7 and simplifying, we obtain:

8x^2 + 2y^2 = 7cos^2θ + 8sin^2θ

Using the identity cos^2θ + sin^2θ = 1, we get:

8x^2 + 2y^2 = 7(1)

Therefore, the Cartesian form of the equation is 8x^2 + 2y^2 = 7.

Answer:y=−4x+7/2

Step-by-step explanation:

Multiply each side of the equation by 8cosθ+2sinθ to get 8rcosθ+2rsinθ=7. Using the relationships x=rcosθ and y=rsinθ, the equation becomes 8x+2y=7. Solving this equation for y shows that y=−4x+7/2.
