In general, to evaluate the function f(x) at a specific value of x, we substitute that value into the expression for f(x) and simplify.

In mathematics, a function is a relation between two sets, where for every element in the first set (called the domain), there is exactly one element in the second set (called the range) that the function maps to. In simpler terms, a function is a rule that assigns each input value from the domain to exactly one output value in the range. Functions are usually represented by a formula or equation that describes the relationship between the input and output values. For example, the function f(x) = 2x + 1 maps every input value of x to an output value that is twice the input value plus 1.

Here,

To evaluate the function f(x) = 4x - 6, we substitute the given values of the independent variable into the expression for f(x) and simplify.

For example:

f(0) = 4(0) - 6 = -6

f(1) = 4(1) - 6 = -2

f(2) = 4(2) - 6 = 2

f(-1) = 4(-1) - 6 = -10

f(3a) = 4(3a) - 6 = 12a - 6

The total cost of producing 500 items is $52,800. The marginal cost of producing the 501st item is $16.60.

The given function for the total cost of producing q items is C(q) = 44,000 + 16.60q. To find the total cost of producing 500 items, we substitute q = 500 into the function and evaluate C(500). Thus, the total cost is C(500) = 44,000 + 16.60 * 500 = 44,000 + 8,300 = $52,800.

To find the marginal cost of producing the 501st item, we need to determine the additional cost incurred by producing that item. The marginal cost represents the change in total cost resulting from producing one additional unit. In this case, to find the cost of producing the 501st item, we can calculate the difference between the total cost of producing 501 items and 500 items.

C(501) - C(500) = (44,000 + 16.60 * 501) - (44,000 + 16.60 * 500)

= 44,000 + 8,316 - 44,000 - 8,300

= $16.60.

Hence, the marginal cost of producing the 501st item is $16.60. It represents the increase in cost when producing one additional item beyond the 500 items already produced

The resulting triangle after reflecting ∆PQR in the line y = -1 and rotating it 90° counterclockwise about the point R is ∆P''Q''R'' with vertices P''(5, 2), Q''(5, 2), and R''(6, -2).

To reflect the triangle ∆PQR in the line y = -1, we can find the images of each vertex by reflecting them across the line.

The reflection of a point (x, y) across the line y = -1 can be obtained by keeping the x-coordinate the same and negating the y-coordinate.

For vertex P(2, 4):

The image of P after reflection will be P' with coordinates (2, -3).

For vertex Q(2, 2):

The image of Q after reflection will be Q' with coordinates (2, -3).

For vertex R(6, 2):

The image of R after reflection will be R' with coordinates (6, -2).

Now, to rotate the reflected triangle 90° counterclockwise about the point R(6, -2), we can use the rotation formulas.

The rotation of a point (x, y) counterclockwise by 90° about the point (a, b) can be obtained using the following formulas:

x' = a + (y - b)

y' = b - (x - a)

Applying these formulas to each vertex of the reflected triangle:

For vertex P', which is (2, -3):

x' = 6 + (-3 - (-2)) = 6 + (-1) = 5

y' = -2 - (2 - 6) = -2 - (-4) = 2

The image of P' after rotation will be P'' with coordinates (5, 2).

For vertex Q', which is (2, -3):

x' = 6 + (-3 - (-2)) = 6 + (-1) = 5

y' = -2 - (2 - 6) = -2 - (-4) = 2

The image of Q' after rotation will be Q'' with coordinates (5, 2).

For vertex R', which is (6, -2):

x' = 6 + (-2 - (-2)) = 6 + (0) = 6

y' = -2 - (6 - 6) = -2 - (0) = -2

The image of R' after rotation will be R'' with coordinates (6, -2).

Therefore, the resulting triangle after reflecting ∆PQR in the line y = -1 and rotating it 90° counterclockwise about the point R is ∆P''Q''R'' with vertices P''(5, 2), Q''(5, 2), and R''(6, -2).

Solution :

For the bigger rectangle

Width of bigger rectangle = W

Length of bigger rectangle, L = 2W

For the smaller rectangle

Width , w = W+4

Length, l = L = 2W

Area, a =120 \(m^2\)

Now we know,

Area = length x width

\($a=l \times w$\)

\($120=(2W) \times (W+4)$\)

\($120=2W^2 + 8W$\)

\($2W^2+8W-120=0$\)

\($W^2+4W-60=0$\)

\($(W+10)(W-6) = 0$\)

We get, either \(W=-10\)   (rejecting)

                or     \(W=6\)

∴ length of the bigger rectangle, \($L=2W $\)

                                                          = 2(6)

                                                           = 12 m

The inverse operation of squaring a number is finding the square root of that number. The square root of a number "x" is the value that, when squared, gives the original number.

When a number is squared, it is multiplied by itself. For example, squaring the number 4 gives 4^2 = 16.

The inverse operation undoes the effect of squaring and returns you to the original number. In this case, finding the square root of a number is the inverse operation of squaring.

The square root of a number "x" is a value that, when squared, gives the original number. It is denoted by the symbol √x.

For example, if you have the number 25 and you want to find its square root, you calculate:

√25 = 5

5 is the square root of 25 because when you square 5 (5^2), you get 25.

To find the sum of the digits of all possible values of 'a', we need to add the sum of the digits of each value of abc. The sum of the digits for all possible values of a would be 8 + 7 + 15 + ... + 27, which can be calculated further.

The divisibility rule for 125 states that a number is divisible by 125 if the last three digits are divisible by 125. In the case of 24687abc, we know that the last three digits (abc) must be divisible by 125. This means that abc must be a multiple of 125. The smallest multiple of 125 is 125, and the largest is 999, so the possible values of abc are 125, 250, 375, 500, ..., 999.

The sum of the digits of each possible value of a can be calculated by adding the individual digits of each value of abc. For example, for the value 125, the sum of the digits is 1 + 2 + 5 = 8. For the value 250, the sum of the digits is 2 + 5 + 0 = 7. For the value 375, the sum of the digits is 3 + 7 + 5 = 15.

Returning, her average speed was 55 mph.

Time taken =  1/3 of an hour longer on the return trip

We have to Find total distance between Detroit and Columbus

So, Let the distance between Detroit and Columbus be "x" miles

Average speed = 60

So, time taken by her to cover distance of x miles with speed of 60 mph

Time = Distance / speed

=> t = x / 60

She Took x/60 hours to reach Columbus

While returning her speed was 55 mph.

So, time taken by her to cover the same distance but at a speed of 55 mph :

=> t = x / 55

Now we are given that she took 1/3 of hour more while returning .

So, \(\frac{x}{55} - \frac{x}{60} = \frac{1}{3}\)

The measure of arc LP is approximately 391.75 degrees.

The sum of the measures of arcs LM and NP is equal to the measure of the entire circumference, which is 360 degrees for a full circle. So we can set up an equation:

LM + NP = 360

Substituting the given expressions for LM and NP, we get:

(8x-56) + (5x+22) = 360

Simplifying and solving for x, we get:

13x - 34 = 360

13x = 394

x ≈ 30.31

Now that we have the value of x, we can find the measure of arc LP by adding the measures of arcs LM and NP:

On average, a customer spends approximately 1.16 minutes waiting time on hold before they can start speaking to a representative.

To find the average waiting time for a customer on hold before they can start speaking to a representative, we need to consider both the arrival rate of calls and the average service time of the staff members.

Given:

9 staff members taking calls.

On average, one call arrives every 5 minutes (standard deviation of 5 minutes).

Each staff member spends on average 18 minutes with each customer (with a standard deviation of 27 minutes).

To calculate the average waiting time, we need to use queuing theory, specifically the M/M/c queuing model. In this model:

"M" stands for Markovian or memoryless arrival and service times.

"c" represents the number of servers.

In our case, we have an M/M/9 queuing model since we have 9 staff members.

The average waiting time for a customer on hold is given by the following formula:

Waiting time = (1 / (c * (μ - λ))) * (ρ / (1 - ρ))

Where:

c = number of servers (staff members) = 9

μ = average service rate (1 / average service time)

λ = average arrival rate (1 / average interarrival time)

ρ = λ / (c * μ)

First, let's calculate the average arrival rate (λ):

λ = 1 / (average interarrival time) = 1 / 5 minutes = 0.2 calls per minute

Next, calculate the average service rate (μ):

μ = 1 / (average service time) = 1 / 18 minutes = 0.0556 customers per minute

Now, calculate ρ:

ρ = λ / (c * μ) = 0.2 / (9 * 0.0556) ≈ 0.407

Finally, calculate the waiting time:

Waiting time = (1 / (c * (μ - λ))) * (ρ / (1 - ρ))

= (1 / (9 * (0.0556 - 0.2))) * (0.407 / (1 - 0.407))

≈ 1.16 minutes

Therefore, on average, a customer spends approximately 1.16 minutes waiting on hold before they can start speaking to a representative.
