Answer: a) Write an equation that represents the amount of water in the first pool after t minutes, assuming water is only being added and not removed.

We can use the formula for uniform motion to represent the amount of water in the first pool after t minutes:

amount of water = initial amount + rate * time

The initial amount of water in the first pool is 872 liters. The rate at which water is being added to the first pool is 18.25 liters per minute. Therefore, the equation that represents the amount of water in the first pool after t minutes is:

A(t) = 872 + 18.25t

b) Write an equation that represents the amount of water in the second pool after t minutes, assuming water is only being added and not removed.

Similar to part (a), we can use the formula for uniform motion to represent the amount of water in the second pool after t minutes:

amount of water = initial amount + rate * time

The initial amount of water in the second pool is 0 liters, since it is initially empty. The rate at which water is being added to the second pool is 45.5 liters per minute. Therefore, the equation that represents the amount of water in the second pool after t minutes is:

B(t) = 0 + 45.5t

c) How long will it take until the two pools have the same amount of water?

To find the time when the two pools have the same amount of water, we can set the two equations from parts (a) and (b) equal to each other:

A(t) = B(t)

872 + 18.25t = 45.5t

Subtracting 18.25t from both sides, we get:

872 = 27.25t

Dividing both sides by 27.25, we get:

t ≈ 32 minutes

Therefore, it will take approximately 32 minutes until the two pools have the same amount of water.

A work covers the connections between various variable that all work together to produce the same result. A utility is made up of a variety of distinctive components that cooperate to create distinct results for each input.

Here,

We must first determine the derivative f'(x) and then solve for f'(x) = 0 in order to determine the critical spots of the function f(x) = 4x - 12ln(9x), where x > 0.

=> f(x) = 4x - 12ln (9x)

=> f'(x) = 4 - 12(1/x) = 4 - 12/x

Now, in order to determine the critical spots, we must solve f'(x) = 0:

=> 4 - 12/x = 0

When we multiply both parts by x, we obtain:

=>4x - 12 = 0

After finding x, we obtain:

=> x = 3

Consequently, the sole turning point is x = 3.

We can use the Second Derivative Test to determine whether this crucial point relates to a maximum, minimum, or neither.

=> f''(x) = 12/x^2

f"(3) = 4, which is positive, when x = 3. This suggests that at x = 3, f(x) has a local minimum.

Step-by-step explanation:

Let's assume that the width of the floral mosaic flag is "x" ft.

According to the problem, the length of the flag is 320 ft greater than the width. So, the length will be x+320 ft.

The perimeter of the flag is given as 2,400 ft.

As the perimeter of a rectangle is given by the formula 2(length + width), we have:

2(x + x+320) = 2400

Simplifying the equation:

2(2x+320)=2400

4x+640=2400

4x=1760

x=440

So, the width of the floral mosaic flag is 440 ft.

And the length of the flag is x+320 = 440+320 = 760 ft.

Therefore, the width of the floral mosaic flag is 440 ft and the length is 760 ft.

Answer:

Since the point (-3, 2) lies on the terminal side of the angle theta in standard position, we can use the Pythagorean theorem to find the length of the hypotenuse:

h = sqrt((-3)^2 + 2^2) = sqrt(9 + 4) = sqrt(13)

Then we can use the definitions of sin and cot:

sin(theta) = opposite/hypotenuse = 2/sqrt(13)

cot(theta) = adjacent/opposite = -3/2

The length of the arc intercepted by a central angle of pi/16 radians in a circle of diameter 24 feet is given by:

L = r * theta

where r is the radius of the circle, which is half the diameter: r = 12 feet. So we have:

L = 12 * (pi/16) = 3pi/4 feet

To approximate to the nearest hundredth, we can use 3.14 for pi:

L ≈ 2.36 feet

So the length of the arc intercepted by the central angle is approximately 2.36 feet.

We can use the law of sines to solve for the remaining angle and side lengths of the triangle:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, c are the side lengths and A, B, C are the opposite angles. We are given a = 9 and b = 10, and A = 42°. We can solve for sin(B) using the equation above:

10/sin(B) = 9/sin(42°)

sin(B) = 10*sin(42°)/9 ≈ 0.742

This means that angle B is acute, and we can solve for it using the inverse sine function:

B = sin^(-1)(0.742) ≈ 47.7°

Now we can find the remaining angle C by subtracting A and B from 180°:

C = 180° - A - B ≈ 90.3°

Finally, we can use the law of sines again to find the remaining side length c:

c/sin(C) = a/sin(A)

c/sin(90.3°) = 9/sin(42°)

c ≈ 11.1

So the solution for the triangle is: a = 9, b = 10, c ≈ 11.1, A = 42°, B ≈ 47.7°, C ≈ 90.3°.

The number of chairs sold must be a non-negative integer, we can round up -10 to 0. Therefore, the minimum number of chairs the store must sell is 0.

Given the constraints in the problem, we can set up the following system of inequalities:

c + t ≤ 30 (the store can ship no more than 30 pieces of furniture)

Rc + Rt ≥ 6500 (the store must sell a minimum of $6500 worth of chairs and tables)

Rc = 150c (the price of a chair is $150)

Rt = 400t (the price of a table is $400)

We know that 10 tables were sold, so we can substitute t = 10 into the first two inequalities:

c + 10 ≤ 30

150c + 4000 ≥ 6500

Simplifying the first inequality, we get c ≤ 20. So the store can sell at most 20 chairs in addition to the 10 tables.

We can set up the following optimization problem:

Maximize 150c

Subject to c + t ≤ 30

Rc + Rt ≥ 6500

Rt = 400t

t = 10

Using substitution, we can rewrite the second constraint as:

150c + 4000 + 400t ≥ 6500

150c + 4000 + 400(10) ≥ 6500

The answer of the given question based on finding the length of EF from the triangle is, the length of EF is approximately 1.2. The answer is (d).

The Law of Sines is a trigonometric rule that relates the angles and sides of a triangle. Specifically, it states that for any triangle ABC, the ratio of the length of a side of the triangle to the sine of the angle opposite that side is equal to the same ratio for any other side and its opposite angle:

a/sin(A) = b/sin(B) = c/sin(C) ,where a, b, and c are the lengths of the sides of the triangle, and A, B, and C are the opposite angles, respectively. This law is useful in solving problems involving triangles, such as finding the length of a side or the measure of an angle when given certain other information about the triangle.

To find the length of EF, we can use the Law of Sines,

Let x be the length of EF. Then we have:

sin(75°)/3 = sin(50°)/x

Solving for x, we get:

x = 3*sin(50°)/sin(75°) ≈ 1.2

Therefore, the length of EF is approximately 1.2. The answer is (d).

Answer:

100%

Step-by-step explanation:

A percentage is a ratio or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

The percentage increase can be found by finding the difference between the two numbers, dividing that difference by the original number, and then multiplying by 100 to get a percentage.

In this case, the difference between the two numbers is:

Dividing this by $100,000:

Multiplying 1 by 100 gives a percentage.

1 × 100 = 100 (100%)

Therefore, the percentage increase is 100%.

The percentage increase in the value is 100%

Percentage is a way to express a number as a fraction of 100. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".

To find the percentage increase, we need to calculate the difference between the old and new values, divide it by the old value, and then multiply by 100 to convert it to a percentage.

The difference between the new value and old value is:

$200,000 - $100,000 = $100,000

To calculate the percentage increase, we divide this difference by the old value:

$100,000 / $100,000 = 1

Finally, we multiply by 100 to convert to a percentage:

1 x 100% = 100%

Therefore, the percentage increase in production value is 100%.
