The rate of change for the water level between Weeks 2 and 3 is: D. 3 7/8.

In Mathematics and Geometry, the gradient, rate of change, or slope of any straight line can be determined by using the following mathematical equation;

Rate of change (slope) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change (slope) = rise/run

Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points into the formula for the slope of a line, we have the following;

Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)

Rate of change (slope) = (1 5/8 + 2 1/4)/(3 - 2)

Rate of change (slope) = (13/8 + 9/4)/(1)

Rate of change (slope) = 3 7/8

Based on the table, the rate of change is the change in y-axis with respect to the x-axis and it is equal to 3 7/8.

Using the composition of functions, if the two functions are inverses of each other, therefore, we cannot conclude if f(x) and g(x) are inverses of each other.

To check if the two functions f(x) and g(x) are inverses of each other, we need to verify if their composition f(g(x)) and g(f(x)) results in the identity function f(x) = x.

Let's first find the composition f(g(x)):

f(g(x)) = f(x^2 - 4)

= sqrt(x^2 - 4) + 4

Now, let's find the composition g(f(x)):

g(f(x)) = g(sqrt(x) + 4)

= (sqrt(x) + 4)^2 - 4

= x + 16 + 8sqrt(x)

To check if f(x) and g(x) are inverses of each other, we need to check if f(g(x)) = x and g(f(x)) = x for all x in the domain of the functions.

For f(g(x)):

f(g(x)) = sqrt(x^2 - 4) + 4

This function is only defined for x > 2, since the square root of a negative number is not real. Therefore, the domain of f(g(x)) is (2, infinity).

For g(f(x)):

g(f(x)) = x + 16 + 8sqrt(x)

This function is only defined for x >= 0, since the square root of a negative number is not real. Therefore, the domain of g(f(x)) is [0, infinity).

Since the domains of f(g(x)) and g(f(x)) do not overlap, we cannot check if they are inverses of each other. Therefore, we cannot conclude if f(x) and g(x) are inverses of each other.

The area inside the square and outside the circle is 0.86 square units.

To find the area inside the square and outside the circle, we need to first find the area of the square and the area of the circle.

Let's assume that the square has sides of length 2 units, which means its area is:

Area of square = side^2 = 2^2 = 4 square units

Now, let's assume that the circle has a radius of 1 unit, which means its area is:

Area of circle = pi * radius^2 = 3.14 * 1^2 = 3.14 square units

To find the area inside the square and outside the circle, we need to subtract the area of the circle from the area of the square:

Area inside square and outside circle = Area of square - Area of circle

                                     = 4 - 3.14

                                     = 0.86 square units

The approximate area that is watered by the sprinkler, we need to use the formula for the area of a circle, which is A = πr^2, where A is the area, π is a constant equal to approximately 3.14, and r is the radius of the circle.

In this case, we are given that the distance from the sprinkler to the outer edge of the circle is 2.5 m, which is the radius of the circle. Therefore, we can substitute this value into the formula and get:

A = [tex]3.14 x 2.5^2[/tex]

A =[tex]19.625 m^2[/tex]

So, the approximate area that is watered by the sprinkler is 19.625 square meters. This means that any plants, grass or other vegetation within this area will receive water from the sprinkler.

It is important to note that this is only an approximation since the shape of the watered area may not be a perfect circle and the sprinkler may not spray water evenly in all directions.

Additionally, the amount of water sprayed by the sprinkler and the time it takes to water the area will also affect the actual amount of water received by the plants.

Janice's monthly payment for her 5-year, 4% APR car loan would be $626.38.

To calculate Janice's monthly payment, we first need to use the formula for calculating loan payments:

Loan Payment = Loan Amount / Discount Factor

The discount factor can be calculated using the following formula:

Discount Factor = [(1 + r)ⁿ] - 1 / [r(1 + r)ⁿ]

Where r is the monthly interest rate (4% divided by 12 months = 0.00333) and n is the total number of payments (5 years x 12 months = 60).

Plugging in the values, we get:

Discount Factor = [(1 + 0.00333)⁶⁰] - 1 / [0.00333(1 + 0.00333)⁶⁰] = 55.8389

The probability of Dai ordering a regular, medium milk is 1/18.

There are 2 types of milk (regular and chocolate), and 3 sizes (small, medium, and large), and 3 levels of fat content (skim, 2%, and whole). So the total number of possible milk orders is:

2 (types of milk) x 3 (sizes) x 3 (fat content) = 18

Dai needs to choose regular milk and medium size, so there is only one way she can order this combination.

The probability of Dai ordering a regular, medium milk is the number of ways she can order a regular, medium milk divided by the total number of possible milk orders:

1 (number of ways to order a regular, medium milk) / 18 (total number of possible milk orders) = 1/18

The AA Similarity Theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. We can complete the figure by drawing a line segment of length 10.5 from point A to point H.

Using this theorem, we can write the following if-then statement to describe the given illustration:

If angle RH is congruent to angle A and angle NH is congruent to angle E, then triangle PHN is similar to triangle AHE.

This means that the corresponding sides of these triangles are proportional to each other. We can use this information to complete the figure by finding the length of side AH.

Since triangle PHN is similar to triangle AHE, we can set up the following proportion:

PH/AH = HN/HE

We know that PH = 6 and HN = 8, and we want to find AH. Let x represent the length of AH.

6/x = 8/14

Cross-multiplying gives us:

6 * 14 = 8 * x

Simplifying:

84 = 8x

Dividing both sides by 8:

x = 10.5

The absolute maximum value on (0, ∞) for f(x) = 4x - 2x ln x is approximately 2e (5.436), which occurs at x = e.

To find the absolute maximum value on (0, ∞) for the function f(x) = 4x - 2x ln x, we need to follow these steps:
1. Determine the critical points of the function by finding its first derivative and setting it equal to zero.
2. Check the critical points for the maximum value.
3. Verify the behavior at the boundary of the interval (0, ∞).

Step 1: Find the first derivative of f(x).
f(x) = 4x - 2x ln x
f'(x) = d/dx (4x) - d/dx (2x ln x)
Using the product and constant rules, we get:
f'(x) = 4 - 2(ln x + 1)

Step 2: Set the first derivative equal to zero to find the critical points.
4 - 2(ln x + 1) = 0
2(ln x + 1) = 4
ln x + 1 = 2
ln x = 1
Solving for x:
x = e^1
x = e (approximately 2.718)

Step 3: Check the behavior at the boundaries.
As x approaches 0 from the right, ln x approaches negative infinity, making the term -2x ln x approach infinity. Since the interval is (0, ∞), we only need to consider the behavior as x approaches ∞. As x goes to infinity, both 4x and -2x ln x will also go to infinity. However, -2x ln x will increase at a slower rate compared to 4x, so f(x) will approach infinity.

Now, we need to check the value of f(x) at the critical point x = e:
f(e) = 4e - 2e ln e
f(e) = 4e - 2e(1)
f(e) = 2e (approximately 5.436)

Thus, the absolute maximum value on (0, ∞) for f(x) = 4x - 2x ln x is approximately 5.436, which occurs at x = e.

The possible dimensions of the rectangular prism are (2x + 3) cm, (x + 4) cm, and 4 cm, or (2x + 3) cm, 4 cm, and (x + 4) cm, where x is a measure in centimeters.

The polynomial 8x² + 44x + 48 represents the volume of a rectangular prism in cubic centimeters, where x is a measure in centimeters.

To find the possible dimensions of the box, we need to factor the polynomial into three factors that represent the length, width, and height of the rectangular prism.

First, we can factor out the greatest common factor of the polynomial, which is 4:

8x² + 44x + 48 = 4(2x² + 11x + 12)

Next, we can factor the quadratic expression inside the parentheses:

2x² + 11x + 12 = (2x + 3)(x + 4)

Therefore, the polynomial can be factored as:

8x² + 44x + 48 = 4(2x + 3)(x + 4)

This means that the dimensions of the rectangular prism could be (2x + 3), (x + 4), and 4, where x is a measure in centimeters. Alternatively, the dimensions could be (2x + 3), 4, and (x + 4).

tan(angle) = opposite side/adjacent side

Step 3: Plug in the known values and solve for the unknown.
tan(35º) = 50 m / shadow length

Step 4: Rearrange the equation to isolate the shadow length.
shadow length = 50 m / tan(35º)
