The derivative of f(x) = 4 ln(8 + 9x) is f'(x) = 36/(8 + 9x).

To find the derivative of f(x), we use the chain rule and the derivative of ln(u) = 1/u. Let u = 8 + 9x, then f(x) = 4 ln(u). Using the chain rule, we have:

f'(x) = (d/dx)(4 ln(u)) = 4 (d/dx)ln(u) = 4(1/u) (du/dx)

To find du/dx, we take the derivative of u with respect to x, which is simply 9. Therefore:

f'(x) = 4(1/u) (du/dx) = 4(1/(8 + 9x)) (9) = 36/(8 + 9x)

Therefore, the derivative of f(x) is f'(x) = 36/(8 + 9x).

The expected number of customers in the system is 0.96.

Given that the arrivals to the drive-up teller window occur at a rate of 0.4 customers per minute, and the service times are exponentially distributed, we can use queuing theory to determine the operating characteristics of the system.

What is the expected number of customers waiting in line?

We can use the queuing formula Lq = (λ^2) / (μ(μ-λ)), where λ is the arrival rate and μ is the service rate. Here, λ = 0.4 and μ is the reciprocal of the average service time, which we need to calculate.

Assuming the bank tellers can serve customers in an average of 2 minutes, then μ = 1/2 = 0.5.

Plugging these values into the formula, we get:

Lq = (0.4^2) / (0.5(0.5-0.4)) = 0.16 customers

Therefore, the expected number of customers waiting in line is 0.16.

What is the expected time a customer spends in the system?

We can use the queuing formula W = (1/μ) + (Lq/λ), where μ is the service rate and λ is the arrival rate, and Lq is the expected number of customers waiting in line.

Using the same values of λ and μ as before, we can calculate Lq as 0.16 customers. Plugging these values into the formula, we get:

W = (1/0.5) + (0.16/0.4) = 2.4 minutes

Therefore, the expected time a customer spends in the system is 2.4 minutes.

What is the expected number of customers in the system (i.e., both waiting and being served)?

We can use the queuing formula L = λW, where λ is the arrival rate and W is the expected time a customer spends in the system.

Plugging in the values of λ and W that we calculated earlier, we get:

L = 0.4 x 2.4 = 0.96 customers

Therefore, the expected number of customers in the system is 0.96.

Step-by-step explanation:

The car will travel 30 2/3 miles in 45 minutes.Oct

Answer:

m = 600 feet/minute

Step-by-step explanation:

In this scenario, the elevation of the hot air balloon can be represented as a linear function of time. Let's use t to denote time in minutes and h(t) to denote the elevation of the balloon in feet at time t.

We know that the balloon starts at an elevation of 300 feet, so we can write the equation of the line as:

h(t) = 600t + 300

The slope of the line represents the rate of change of the elevation with respect to time, which is the same as the rate at which the balloon is ascending. Therefore, the slope of the line is equal to the ascent rate of the balloon, which is 600 feet per minute.

So the slope of the line is:

m = 600 feet/minute

The basic yearbook option costs $80, and the deluxe yearbook option costs $120.

To find the cost of each yearbook option, we can set up a system of equations based on the given information. Let's denote the cost of a basic yearbook as 'B' and the cost of a deluxe yearbook as 'D'.

From Mrs. Lane's class:

27B + 28D = 4135 (equation 1)

From Mr. Burton's class:

16B + 8D = 1720 (equation 2)

To solve this system of equations, we can use either substitution or elimination. Let's use the elimination method:

Multiplying equation 2 by 2, we have:

32B + 16D = 3440 (equation 3)

Now, subtract equation 3 from equation 1 to eliminate 'D':

(27B + 28D) - (32B + 16D) = 4135 - 3440

Simplifying, we get:

-5B + 12D = 695 (equation 4)

Now we have a new equation relating only 'B' and 'D'. We can solve this equation together with equation 2 to find the values of 'B' and 'D'.

Multiplying equation 4 by 8, we have:

-40B + 96D = 5560 (equation 5)

Adding equation 2 and equation 5:

16B + 8D + (-40B + 96D) = 1720 + 5560

Simplifying, we get:

-24B + 104D = 7280

Dividing the equation by 8, we have:

-3B + 13D = 910 (equation 6)

Now we have a new equation relating only 'B' and 'D'. We can solve this equation together with equation 2 to find the values of 'B' and 'D'.

Now, we have the following system of equations:

-3B + 13D = 910 (equation 6)

16B + 8D = 1720 (equation 2)

Solving this system of equations will give us the values of 'B' and 'D', which represent the cost of each yearbook option.

Solving the system of equations, we find:

B = $80 (cost of a basic yearbook)

D = $120 (cost of a deluxe yearbook)

Therefore, the basic yearbook option costs $80, and the deluxe yearbook option costs $120.

Step-by-step explanation:

The payback period for the auto is approximately 8 years.

Buy-Rite Pharmacy has purchased an auto for delivering prescriptions. The auto was purchased for $26,000, and it has a useful life of 6 years with a $5,500 salvage value. By delivering prescriptions, the pharmacy aims to increase gross revenues by at least $33,500 per year. The pharmacy will incur a cost of $28,000 per year for these prescriptions.

Using the straight-line method, the annual depreciation of the auto is ($26,000 - $5,500) / 6 = $3,917. This means that the total cost of the auto over 6 years will be $26,000 - $5,500 + ($3,917 x 6) = $43,502.

To calculate the payback period, we need to determine how long it will take for the increased gross revenues to cover the cost of the auto.

The net increase in revenues will be $33,500 - $28,000 = $5,500 per year. Therefore, the payback period is $43,502 / $5,500 = 7.9 years, which is rounded to 8 years.

Step-by-step explanation:

other answer is cryptic so here is a full explaination

To find the regular price of the hat, we need to determine the amount of the discount and then add that amount to the discount price.

The discount on the hat is 20% of the regular price, or 20/100 * regular price. The discount price is $18, so we can set up the equation:

discount price = regular price - (20/100 * regular price)

Substituting the known values into the equation, we get:

$18 = regular price - (20/100 * regular price)

Solving for the regular price, we find that the regular price is $22.50. This is the price of the hat before the discount.

We can conclude that there is no profit-maximizing level of production, and the correct option is e.

None of the above.

Part A The given demand function of a commodity is Q = 20 - 0.01P, and the given cost function is C(Q) = 60 + 6Q.

We need to find out the total revenue function TR in terms of P.

Now, the total revenue is calculated by the multiplication of price and quantity.

Therefore, we can write that TR = P × QSubstituting the value of Q from the demand function, we get;TR = P (20 - 0.01P)TR = 20P - 0.01P²

Therefore, the correct option is c. TR = 20P - 0.01P².

Part BWe are given a production function that is Q = 300L - 4L, where L denotes the size of workforce.

We need to find out the value of the marginal product of labor when L = 9.

Marginal product of labor (MPL) can be calculated as the derivative of the production function with respect to L.

Therefore, we get;MPL = dQ/dL= 300 - 8LNow, substituting the value of L = 9, we get;MPL = 300 - 8(9)MPL = 300 - 72MPL = 228Therefore, the correct option is d. 228Part C

The given total revenue function is TR = 20Q - 4Q², and the given total cost function is TC = 16 - Q²/3.

We know that profit (π) can be calculated as π = TR - TC

Substituting the given values, we get;π = 20Q - 4Q² - (16 - Q²/3)π = -4Q² + (20 - Q²/3)π = -4Q² + 60/3 - Q²/3π = -13Q²/3 + 20Now, we can find the optimal value of Q by differentiating the profit function with respect to Q and equating it to zero.

Therefore, we get;dπ/dQ = -26Q/3 = 0Q = 0

Therefore, we can conclude that there is no profit-maximizing level of production, and the correct option is e.

Answer:

f(2) = -6

f inverse of 1/2 is 17/2

Step-by-step explanation:

We are given a function \(\displaystyle \large{f(x) = \frac{6}{2x-5}}\)

To solve for part (a), we have to substitute x = 2 in f(x).

\(\displaystyle \large{f(2)=\frac{6}{2(2)-5} \\\displaystyle \large{f(2)=\frac{6}{4-5}=\frac{6}{-1}=-6\)

Therefore, f(2) is -6.

Now we solve for part (b), we see the notation which is a minor different similar to f(x). We see that there is exponent of -1 between f and 1/2. The part (b) indicates that the function is an inverse of f(x).

\(\displaystyle \large{y=f^{-1}(x) \longrightarrow x=f(y)}\)

To solve for part (b), first we solve for x in the function. Let f(x) = y.

\(\displaystyle \large{y=\frac{6}{2x-5}}\)

Multiply both sides by 2x-5.

\(\displaystyle \large{y(2x-5)=\frac{6}{2x-5}(2x-5)}\\\displaystyle \large{y(2x-5)=6}\)

Divide both sides by y-term.

\(\displaystyle \large{\frac{y(2x-5)}{y}=\frac{6}{y}}\\\displaystyle \large{2x-5=\frac{6}{y}}\\\displaystyle \large{2x=\frac{6}{y}+5}\\\displaystyle \large{x=\frac{6}{2y}+\frac{5}{2}}\\\displaystyle \large{x=\frac{3}{y}+\frac{5}{2}}\)

Then swap x and y which we receive \(\displaystyle \large{y=\frac{3}{x}+\frac{5}{2}}\)

Therefore, \(\displaystyle \large{f(x)=\frac{6}{2x-5} \longrightarrow f^{-1}(x)=\frac{3}{x}+\frac{5}{2}}\)

Thus, \(\displaystyle \large{f^{-1}(\frac{1}{2})=\frac{3}{\frac{1}{2}}+\frac{5}{2}}\\\displaystyle \large{f^{-1}(\frac{1}{2})=6+\frac{5}{2}}\\\displaystyle \large{f^{-1}(\frac{1}{2})=\frac{17}{2}}\)

Answer:

A = 72, P = 38

Step-by-step explanation:

Area can be found by getting the area of the overall figure, and then subtracting the blank space in the corner

12 * 7 = 84

3 * 4 = 12(invisible rectangle in top right)

84 - 12 = 72

Perimeter can be found by adding all of the sides

12 + 7 + (12-4) + 3 + 4 + (7-4)

The numbers in brackets are the unlabeled sides on the top and left.

Answer:

\(P=38\\ A=72\)

Step-by-step explanation:

To find the perimeter (P), add up all of the side lengths of the figure:

(numbers in parenthesis are the unlabeled values in the figure).

\(12+7+(8)+3+4+(4)=38\)

To find the area of the figure (A), multiply the length and width of the original rectangle \((12*7=84)\). Then, subtract this amount (84) minus the area of the missing rectangle in the top left corner \((4*3=12)\).

Subtract the required values: \(84-12=72\).

Therefore, the perimeter of the figure is 38 units, and the area of the figure is 72 units.
