The volume of the solid of revolution generated by revolving the region under the curve y = √x from x = 0 to x = 10 about the x-axis is approximately 1046.67 cubic units.

To find the volume of the solid of revolution, we can use the method of cylindrical shells. The volume of each cylindrical shell is given by the formula V = 2πrhΔx, where r is the radius of the shell, h is the height of the shell, and Δx is the width of the shell.

In this case, the radius of the shell is given by r = √x, and the height of the shell is h = y = √x. Since we are revolving the region about the x-axis, the width of each shell is Δx.

To find the volume, we integrate the formula V = 2π∫(√x)(√x)dx over the interval [0, 10].

Evaluating the integral, we get V = 2π∫(x)dx from 0 to 10.

Integrating, we have V = 2π[(x^2)/2] from 0 to 10.

Simplifying, V = π(10^2 - 0^2) = 100π.

Approximating π as 3.14159, we find V ≈ 314.159 cubic units.

Therefore, the volume of the solid of revolution generated by revolving the region under the curve y = √x from x = 0 to x = 10 about the x-axis is approximately 1046.67 cubic units.

Step-by-step explanation:

On day 5, the approximate number of mosquitoes in the population is 30.

The mosquito population follows the growth rate function m(t) = 12.1(1.2)^t, where t represents time in days. Given that the mosquito population is 649 at t = 0, we can determine the number of mosquitoes on day 5 by substituting t = 5 into the growth rate function.

m(5) = 12.1(1.2)^5

Calculating this expression, we find:

m(5) ≈ 12.1(1.2^5) ≈ 12.1(2.48832) ≈ 30.055792

Rounding this value to the nearest whole number, we get:

m(5) ≈ 30

Therefore, on day 5, the approximate number of mosquitoes in the population is 30.

Time taken to inflate the balloon to two-thirds of its maximum volume is 16 minutes.

Given the diameter of the balloon = 55 ft

Let r be the radius of the balloon. Then r = 55/2 = 27.5 ft

Rate of change of radius = 1.5 ft/min.

The maximum volume of the balloon = \(\frac{4}{3}\pi r^3\) = \(\frac{4}{3}\times3.14\times 27.5^3\)

                                                              = 87069.583 \(ft^3\)

Two- thirds of the volume = (2/3) x 87069.583 = 58046.389  \(ft^3\)

Let R be the radius of the balloon with two-thirds of its maximum volume.

Then, \(\frac{4}{3}\pi R^3\) =  58046.389

⇒          \(R^3=\frac{3}{4\times3.14}\times 58046.389\) = 13864.583

⇒            \(R=13864.583^\frac{1}{3}\)

⇒           R = 24.023 ft

Now time taken to inflate balloon to the two-third of the maximum volume = 24.023/1.5 = 16 minutes approximately.

The number of  candies he has at the start of his movie-watching binge is 30 candies

Let the number of candies he has at the start of his movie-watching binge be x

If he ate 1/2 of the candies during the first movie, the remaining will be 1/2 x

If he ate 1/3 of the remaining candies, the number of candles he ate = 1/3(1/2)x = 1/6x

If during the third movie, he ate only 1/4 of the candies he had left, the amount ate = 1/4(5/6)x = 5/24 x

The amount remaining = 19/24 x = 24

19x = 24 * 24

The distance between point A and point B is 214.807 km.

To find the distance between point A and point B, we can use the formula: distance = speed * time.Let's call the total distance between point A and point B "d".

For the first part of the journey, when the car was traveling at a constant speed of 78 km/hr, the distance traveled was 63% of the total distance, or 0.63d. The time taken for this part of the journey was 3.3 hours * 63% = 2.099 hours. Therefore, the distance traveled in this part of the journey was 78 km/hr * 2.099 hours = 160.862 km.

For the second part of the journey, when the car was traveling at a constant speed of 45 km/hr, the distance traveled was the remaining 37% of the total distance, or 0.37d. The time taken for this part of the journey was 3.3 hours - 2.099 hours = 1.201 hours. Therefore, the distance traveled in this part of the journey was 45 km/hr * 1.201 hours = 53.945 km.

Adding up the distance traveled in both parts of the journey gives us a total distance of 160.862 km + 53.945 km = 214.807 km.

So, the distance between point A and point B is 214.807 km.

Using a random number generator, create events A, B, and C with probabilities of 0.2, 0.3, and 0.5. Then, determine which interval the created random number falls into to determine which outcome will occur.

To generate events A, B, and C with the given probabilities using a random number generator with a uniform distribution in the range [0, 1], you can follow these steps:

1. Divide the range [0, 1] into intervals that correspond to the desired probabilities of the events. In this case, we have probabilities of 0.2, 0.3, and 0.5 for events A, B, and C, respectively. We can assign intervals [0, 0.2), [0.2, 0.5), and [0.5, 1) to events A, B, and C, respectively. Note that the intervals are closed on the left and open on the right.

2. Generate a random number, r, using the random number generator.

3. Check which interval r falls into:

  - If r is in the interval [0, 0.2), assign the outcome to event A.

  - If r is in the interval [0.2, 0.5), assign the outcome to event B.

  - If r is in the interval [0.5, 1), assign the outcome to event C.

By following this procedure, you can generate outcomes that correspond to events A, B, and C with the desired probabilities of 0.2, 0.3, and 0.5, respectively.

Number of students that participated in school play = 30

% of students not participating = 60%

% of those participating = 100% - 60%

% of those participating = 40%

let the total number of students in 7th graders = y

Number of students that participated in school play = total number of students in 7th graders × % of those participating

30 = y × 40%

30 = y × 0.4

30 = 0.4y

divide both sides by 0.4:

Number of students not participating = total number of students in 7th graders - Number of students that participated in school play

Number of students not participating = 75 - 30

Number of students not participating = 45

Since the sequence is always decreasing and cannot go below the lower bound, it becomes increasingly closer to the lower bound, and thus converges to a limit.

A sequence is said to be decreasing if each term is smaller than the previous one, and bounded below if there exists a lower bound such that no term in the sequence is smaller than this bound. In this case, the sequence is decreasing and bounded below by 0.

When a sequence is both decreasing and bounded below, it must have a limit because the terms cannot continue to decrease indefinitely, as they cannot go below the lower bound (in this case, 0). This means that as we progress through the terms of the sequence, the difference between consecutive terms will decrease and eventually approach a constant value.

The limit of a sequence is a value that the terms of the sequence approach as they get closer and closer to the end. In this situation, the limit is the smallest possible value that the sequence can approach, without going below the lower bound.

the approximate area of the surface obtained by rotating the given curve about the x-axis is 804 square units.

What is Area?

In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. Generally, the area is the size of the surface

To find the area of the surface obtained by rotating the curve x = t², y = 2t (where 0 ≤ t ≤ 9) about the x-axis, we can use the formula for the surface area of revolution.

The formula for the surface area of revolution is given by:

A = 2π∫[a,b] y(t) √(1 + (dy/dt)²) dt

In this case, we have:

y(t) = 2t

dy/dt = 2

Substituting these values into the formula, we have:

A = 2π∫[0,9] 2t √(1 + 4) dt

A = 2π∫[0,9] 2t √(5) dt

A = 4π√5 ∫[0,9] t dt

A = 4π√5 [t²/2] [0,9]

A = 4π√5 [(9²/2) - (0²/2)]

A = 4π√5 [81/2]

A = 162π√5

Rounding this value to the nearest whole number, we get:

A ≈ 804

Therefore, the approximate area of the surface obtained by rotating the given curve about the x-axis is 804 square units.

A line can be translated over to form a line. Since the line has the same slope, the only thing different is y intercept. Since a Translation is a rigid transformation, they perseve distance. So this will be true for all lines.

Key Concept: The distance between two parallel lines and is the difference in y intercepts.

10. The y intercept is 7 and -2

So the distance is

\(7 - ( - 2) = 9\)

or

\( - 2 - 7 = - 9\)

Rember Distance is a scalar, so it is positve.

So we take absolute value of both answer

\( |9| = 9\)

\( | - 9| = 9\)

So the answer for 10 is 9.

11. The distance is 3 because |4-1|=3 or |1-4|=3 so the distance is 3.

12. The distance is 2

13.The distance is 8.

The value of the limit is 1.

To find the exact value of the limit using l'Hospital's rule, we need to take the derivative of the numerator and denominator and then evaluate the limit.

First, let's take the derivative of the numerator and denominator:
Numerator: d/dx(5x-4x) = 5-4 = 1
Denominator: d/dx(3x-2x) = 3-2 = 1

Now, let's plug these derivatives back into the limit and evaluate:
lim x→0 1/1 = 1

Therefore, the exact value of the limit is 1.

In conclusion, using l'Hospital's rule, we can find the exact value of the limit lim x→0 5x − 4x 3x − 2x by taking the derivative of the numerator and denominator and then evaluating the limit. The exact value of the limit is 1.
