The height of the rectangular recycling bin is 7 ft.

To find the height of the rectangular recycling bin, we can use the formula for the surface area of a rectangular box:

Surface Area = 2lw + 2lh + 2wh

Given:

Length (l) = 16 ft

Width (w) = 9 ft

Surface Area = 638 ft²

Substituting these values into the surface area formula, we have:

638 = 2(16)(9) + 2(16)h + 2(9)h

638 = 288 + 32h + 18h

638 = 288 + 50h

350 = 50h

h = 350 / 50

h = 7

Therefore, the height of the rectangular recycling bin is 7 ft.

The given sequence does not follow a simple arithmetic or geometric pattern, making it challenging to determine an explicit rule based on the given terms.

To identify the type of sequence and write the explicit rule, we need to examine the pattern of the given sequence: -39, -45, 51, 57, ...

By observing the differences between consecutive terms, we can determine if it follows an arithmetic or geometric pattern.

Arithmetic sequences have a common difference between each term, meaning that by adding (or subtracting) the same value repeatedly, we can generate the sequence. Geometric sequences, on the other hand, have a common ratio between each term, meaning that by multiplying (or dividing) by the same value repeatedly, we can generate the sequence.

Let's calculate the differences between consecutive terms:

-45 - (-39) = -6

51 - (-45) = 96

57 - 51 = 6

From the differences, we can see that the sequence is not arithmetic since the differences are not constant. However, the differences alternate between -6 and 6, indicating a possible geometric pattern.

Let's calculate the ratios between consecutive terms:

-45 / (-39) ≈ 1.1538

51 / (-45) ≈ -1.1333

57 / 51 ≈ 1.1176

The ratios are not constant, indicating that the sequence is neither geometric nor arithmetic.

The cruise ship's resultant velocity is approximately 22.67 mph, and its direction is approximately 10.2 degrees south of east.

To find the resultant direction, we can use vector addition. Let's represent the southward velocity of the cruise ship as vector A and the eastward velocity of the Gulf Stream as vector B.

Given:

Magnitude of vector A (southward velocity of the cruise ship) = 22 mph

Magnitude of vector B (eastward velocity of the Gulf Stream) = 4 mph

To find the resultant velocity, we add the two vectors together. Since the vectors are perpendicular to each other, we can use the Pythagorean theorem to find the magnitude of the resultant vector:

Resultant velocity = √(A^2 + B^2) = √(22^2 + 4^2) ≈ 22.67 mph

Now, to find the direction of the resultant vector, we can use trigonometry. The angle between the resultant vector and the south direction can be calculated as:

b. g(x) = x + 2

a) To find two functions f and g such that (fog)(x) = 1/(x + 2), we need to determine how the composition of the two functions f and g produces the given expression.

Let's start by assuming g(x) = x + a, where a is a constant. This means that g(x) adds the constant a to the input x.

Next, let's determine the function f(x) such that (fog)(x) results in the desired expression. We have:

(fog)(x) = f(g(x)) = f(x + a)

b) To simplify the expression 1/(x + 2) and make it match f(g(x)), we can consider f(x) = 1/x.

Substituting the expressions for f(x) and g(x) into (fog)(x), we have:

(fog)(x) = f(g(x)) = f(x + a) = 1/(x + a)

Comparing this with the desired expression 1/(x + 2), we see that a = 2. Therefore, the functions f and g are:

a. f(x) = 1/x

b. g(x) = x + 2

Using these functions, we can verify the composition (fog)(x):

(fog)(x) = f(g(x)) = f(x + 2) = 1/(x + 2)

The amount that B gets.

Let's suppose the amount B gets is x.

Now, we can proceed as given below:

Given that the total amount = $5000

Amount received by A = (1/4) * (Amount received by B and C)

Amount received by B = (1/3) * (Amount received by A and C)

Amount received by C = (Amount received by B and A) - (Amount received by B)

Now, we have,Amount received by B + Amount received by C = 3 * Amount received by B/3 + Amount received by A/3

Amount received by A = (1/4) * [Amount received by B + Amount received by C]

Amount received by B = (1/3) * [Amount received by A + Amount received by C]

Amount received by C = [Amount received by B + Amount received by A] - [Amount received by B]

Let's solve this problem in detail: Amount received by A = (1/4) * (Amount received by B + Amount received by C)

Now, Amount received by A = (1/4) * ($5000 - Amount received by A)

By solving the above equation,

Amount received by A = $1000Amount received by B = (1/3) * (Amount received by A + Amount received by C)

Also, Amount received by B + Amount received by C = 3 * Amount received by B/3 + Amount received by A/3

Again, $5000 - Amount received by A = 2 * (Amount received by B + Amount received by C)

By substituting the value of Amount received by A in the above equation,Amount received by B + Amount received by C = $3000

These are two linear equations with two unknowns, P (price of pants) and S (price of socks). You can solve them by using either substitution or elimination methods.

Let's use the elimination method.

First, let's subtract the second equation from the first:

1P + 2S - (1P + 3S) = 60 - 75

After simplifying this, we get:

-1S = -15

Dividing both sides by -1, we find:

S = 15

Now, we can substitute S = 15 into the first equation to find the price of pants (P):

1P + 2(15) = 60

1P + 30 = 60

Subtract 30 from both sides to get:

1P = 60 - 30

1P = 30

So, the price of one pair of pants (P) is $30.

The price that should be charged to maximize profits:  $80.5 (option a).

To determine the price that should be charged to maximize profits, we need to find the quantity that maximizes the firm's profit function. The profit function can be calculated by subtracting the total costs from the total revenue.

First, let's find the total revenue function. The demand equation given is P = 78 − 15Q, where Q = Q1 + Q2. We can rearrange this equation to express Q in terms of P: Q = (78 - P) / 15.

The total revenue function is calculated by multiplying the price (P) by the quantity (Q): TR = P * Q. Substituting Q, we get TR = P * [(78 - P) / 15].

Next, we need to find the total cost function. The marginal costs associated with producing in the two plants are MC1 = 3Q1 and MC2 = 2Q2. The total cost is the sum of the costs in both plants: TC = MC1 + MC2. Substituting the respective marginal cost equations, we get TC = 3Q1 + 2Q2.

Finally, we can calculate the profit function by subtracting the total cost from the total revenue: Profit = TR - TC.

Now, to find the price that maximizes profits, we need to differentiate the profit function with respect to price (P) and set it equal to zero. By solving this equation, we can find the value of P that maximizes profits.

Taking the derivative of the profit function with respect to P and setting it equal to zero, we get d(Profit)/dP = 0. Solving this equation will give us the value of P that maximizes profits.

After solving the equation, we find that P = $80.5 maximizes profits. Therefore, the price that should be charged to maximize profits is A) $80.5.

Answer: Assuming that you're asking what the y-intercept is, 11.2.

Step-by-step explanation:

y = mx + c,

where m is the slope and c is the y-intercept.

To calculate the slope, we use the formula:

m = (y2 - y1) / (x2 - x1),

where (x1, y1) and (x2, y2) are the coordinates of points A and B, respectively.

Using the coordinates of points A and B, we have:

m = (7 - 0) / (3 - 8)

m = 7 / (-5)

m = -7/5

Now we can substitute the values of the slope (m) and the coordinates of one point (A) into the slope-intercept form to solve for the y-intercept (c):

0 = (-7/5)(8) + c

0 = -56/5 + c

To isolate c, we can add 56/5 to both sides:

56/5 = c

Therefore, the y-intercept of the line passing through points A (8, 0) and B (3, 7) is (0, 56/5) or 11.2 when expressed as a decimal.
