Step-by-step explanation:

The volume of a tennis ball is about 8.65 cubic inches

The volume of the space within the cylinder not taken up by the tennis balls is about 25.44 cubic inches

From the question, we are to determine the volume of a tennis ball

From the given information,

The circumference of a tennis ball is 8 inches

That is,

C = 2πr (C is circumference)

8 = 2πr

∴ r = 8/2π

r = 4/π inches

This the radius of a tennis ball

Now, for the volume of a tennis ball

Using the formula for calculating the volume of a sphere

\(V = \frac{4}{3}\pi r^{3}\)

Then, the volume of a tennis is

\(V = \frac{4}{3}\pi \times (\frac{4}{\pi})^{3}\)

\(V = \frac{4}{3}\pi \times \frac{64}{\pi^{3}}\)

\(V = \frac{256}{3\pi^{2}}\)

V = 8.64607 cubic inches

V ≅ 8.65 cubic inches

Hence, the volume of a tennis ball is about 8.65 cubic inches

b. To find the amount of space within the cylinder not taken up by the tennis balls

First, we will calculate the volume of the cylinder

Using the formula for calculating the volume of a cylinder

V = πr²h

Where V is the volume

r is the radius

and h is the height

From the given information,

r = 1.43 inches

h = 8 inches

Putting the parameters into the formula, we get

V = π × 1.43² × 8

V = 16.3592π

V = 51.39 cubic inches

This is the volume of the cylinder

Now, for the amount of space within the cylinder not taken up by the tennis balls

Since there are three tennis balls,

The amount of space not taken up will be

51.39 cubic inches - 3(8.65 cubic inches)

51.39 cubic inches - 25.95 cubic inches

= 25.44 cubic inches

Hence, the volume of the space within the cylinder not taken up by the tennis balls is about 25.44 cubic inches

Answer:

Step-by-step explanation:

Answer:

a. h = A/w = 2 ³/₄ ft

b. A'/A = 2/3

Step-by-step explanation:

a. What is the total height of the wall? Write an equation to represent the situation. Then solve.

The wall is a rectangle and its area is A = wh where w = width and h = height of wall.

Making h subject of the formula,

h = A/w

Now, Since the area of the retaining wall, A is 23 ³/₈ ft² and its width is the length of the portion of the wall which is brick w is 8 ¹/₂ ft, then

h = A/w

= 23 ³/₈ ft² ÷ 8 ¹/₂ ft

= 187/8 ft² ÷ 17/2 ft

= 187/8 ft² × 2/17 ft

= 187/4 ft² × 1/17 ft

= 187/68 ft

= 2 ³/₄ ft

b. If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.

Since the area of the brick portion of the wall is A' = 15 ⁷/₁₂ ft²  and the total are of the retaining wall is A =  23 ³/₈ ft²

The fraction of the wall that is brick = A'/A

= 15 ⁷/₁₂ ft² ÷ 23 ³/₈ ft²

= 187/12 ÷ 187/8

= 187/12 × 8/187

= 8/12

= 2/3

Answer with Step-by-step explanation:

a) 2 3/4 ÷ 3 = 11/12 feet

11/12 + 11/12 = 1 5/6

Or, you could write an algebraic equation:

2 3/4 ÷ 3 = x.  (3x = 2 3/4)

x = 11/12

The height of the brick proportion of the wall is 1 5/6

b)

You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.

So, your rounded answer should be 16. Or 16 1/2

c)  

Area = 8 1/2 x 2 3/4.

Use Distributive Property to solve the area.

(8 x 2) + (3/4 x 1/2) = x

8 x 2 = 16

3/4 x 1/2 = 3/8

16 + 3/8 = 16 3/8

x = 16 3/8

I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

(a) The improper integral \(\int(sec^2(\theta) d\theta)\) diverges to +∞.

(b) The improper integral \(\int((5/x) + (2ln(3/2))ln(x) dx)\)diverges to +∞.

(c) The improper integral \(\int (e^{(2x)}dx)\) converges to a finite value.

(a) The improper integral ∫(0 to π/4) tan(x) dx diverges to +∞.

To evaluate this integral, we can rewrite tan(x) as sin(x)/cos(x) and then use the substitution method.

Let u = cos(x), so du = -sin(x) dx.

When x = 0, u = cos(0) = 1, and when x = π/4, u = cos(π/4) = √2/2.

The integral becomes:

∫(0 to π/4) tan(x) dx = ∫(1 to √2/2) (-1/u) du = -∫(1 to √2/2) du/u

Evaluating this integral:

-∫(1 to √2/2) du/u = -[ln|u|] from 1 to √2/2 = -[ln(√2/2) - ln(1)] = -[ln(√2/2) - 0] = -ln(√2/2) = -ln(1/√2) = -ln(√2) = -ln(2)/2

Therefore, the integral ∫(0 to π/4) tan(x) dx diverges to +∞.

(b) The improper integral ∫(0 to 5) (5 + 2ln(3/2)) ln(x) dx diverges to +∞.

Since the integrand is always positive and the limits of integration are finite, the integral does not converge to a finite value but rather goes to +∞.

(c) The improper integral\(\int (2 $ to \infty ) e^x\)dx converges.

To evaluate this integral, we integrate the function \(e^x\) with respect to x and then evaluate the limits of integration.

\(\int (2 $ to \infty ) e^x dx\) = lim(t→∞) ∫(2 to t) \(e^x\) dx = lim(t→∞) \([e^t - e^2]\)

Since the limit of the exponential function \(e^t\)  as t approaches infinity is +∞, the integral ∫(2 to ∞) \(e^x\) dx converges to a finite value, \(e^2 - e^2 = 0.\)

Therefore, the integral ∫(2 to ∞) \(e^x\) dx converges.

The probability that all five balls drawn out of the box at random are white is approximately 0.001082.

To find the probability that all five balls drawn out of the box at random are white, follow these steps:

1. Calculate the total number of balls in the box: 5 white balls + 6 black balls = 11 balls
2. Determine the probability of drawing the first white ball: 5 white balls / 11 total balls = 5/11
3. After drawing the first white ball, there are now 4 white balls and 10 total balls remaining. Determine the probability of drawing the second white ball: 4 white balls / 10 total balls = 4/10
4. After drawing the second white ball, there are now 3 white balls and 9 total balls remaining. Determine the probability of drawing the third white ball: 3 white balls / 9 total balls = 1/3
5. After drawing the third white ball, there are now 2 white balls and 8 total balls remaining. Determine the probability of drawing the fourth white ball: 2 white balls / 8 total balls = 1/4
6. After drawing the fourth white ball, there is now 1 white ball and 7 total balls remaining. Determine the probability of drawing the fifth white ball: 1 white ball / 7 total balls = 1/7

To find the probability of all five events occurring, multiply the probabilities together: (5/11) * (4/10) * (1/3) * (1/4) * (1/7) = 0.00108225108

So, the probability that all five balls drawn out of the box at random are white is approximately 0.001082, or 0.1082%.

Using linear approximation, the value of f(3.01) can be approximated by evaluating the tangent line to the function f(x) = x^2 at x = 3 and using it to estimate the value at x = 3.01.

Linear approximation is a method used to estimate the value of a function near a specific point by considering the tangent line at that point. The tangent line is a linear function that approximates the behavior of the original function in the vicinity of the point.

To approximate f(3.01) using linear approximation, we start by finding the slope of the tangent line at x = 3. This can be done by taking the derivative of f(x) = x^2, which is f'(x) = 2x. Evaluating f'(3) gives us the slope of the tangent line at x = 3.

Next, we use the point-slope form of a linear equation to write the equation of the tangent line. Plugging in the values x = 3, y = f(3) = 9, and the slope from f'(3), we can determine the equation of the tangent line.

Finally, we evaluate the tangent line at x = 3.01 to approximate the value of f(3.01). This can be done by substituting x = 3.01 into the equation of the tangent line and solving for y. The resulting value is an approximation of f(3.01) using linear approximation.

Step-by-step explanation:

subsitude the values into the formula i gave you. you should be able to get the answer.

The system of equations that matches the given graph is:

A. 3x - 6y = 12

9x - 18y = 36

To determine which system of equations matches a given graph, we need to analyze the slope and intercepts of the lines in the graph.

Looking at the options provided:

A. 3x - 6y = 12

9x - 18y = 36

B. 3x + 6y = 12

9x + 18y = 36

Let's analyze the equations in each option:

For option A:

The first equation, 3x - 6y = 12, can be rearranged to slope-intercept form: y = (1/2)x - 2.

The second equation, 9x - 18y = 36, can be simplified to 3x - 6y = 12, which is the same as the first equation.

In option A, both equations represent the same line, as they are equivalent. Therefore, option A does not match the given graph.

For option B:

The first equation, 3x + 6y = 12, can be rearranged to slope-intercept form: y = (-1/2)x + 2.

The second equation, 9x + 18y = 36, can be simplified to 3x + 6y = 12, which is the same as the first equation.

In option B, both equations also represent the same line, as they are equivalent. Therefore, option B does not match the given graph.

When we compute the deviation of the second observation in the data set from the mean, and find that the result is a negative number, this tells us that there is good reason to use the median as opposed to the mean as a measure of central tendency.

In computing deviations, it is important to note that extremely skewed deviations can increase the normal distributions and make it difficult to use the standard deviation as a measure of central tendency.

So, when the deviation of the second observation is a negative number, the distribution will be affected and it may become better to use the median as a measure of central tendency.

Answer:

a. y = 3x + 4.5 & y = 7x + 2

b. x = 0.625 (year)

c. 6.375 feet

Explanation:

Type A starts at 4.5 and Type B starts at 2 ,each year can be marked as x

type A grow 3 inches per year = 3x

type B grows 7 inches per year = 7x

y = the total height

Since they both equal to y, you can set them equal to each other

3x + 4.5 = 7x +2

After solve you get answer for b

Work:  3x + 4.5 = 7x + 2

              4.5 = 4x + 2

               2.5 = 4x

              0.625 = x

Substitute the value of x you got from part b into each equation then you will get 6.375 as your y value which is also your height

If segment BD is congruent to segment BC, and BD = 4x - 18, BC = x + 3, and AC = 34, then AB = 31/x.

Let the equation be AB + BC = AC

substitute the values in the above equation, we get

AB + x + 3 = 34

simplifying the value of x,

Subtract A B from both sides AB + x + 3 - AB = 34 - A B

x + 3 = 34 - AB

Subtract 3 from both sides,

x + 3 - 3 = 34 - AB - 3

x = -AB + 31

Plug in this value of x into the line segments to find BC and AC.

Where, BC = x + 3

substitute the value of x in the above equation, we get

BC = [-AB + 31 ] + 3

BC = -AB + 34

Then, AB + BC = AC

x = -AB + 31

AB = 31/x

Hence, If segment BD is congruent to segment BC, and BD = 4x - 18,

BC = x + 3, and AC = 34, then AB = 31/x.
