A truck driver operates a delivery service in a southern city. His​ start-up costs amounted to ​$2500. He estimates that it cost

s him​ (in terms of​ gasoline, wear and tear on his​ truck, etc.)​$3.00 per delivery. He charges ​$5.50 per delivery. Let x represent the number of deliveries he makes. ​(a) Express the cost C as a function of x. ​(b) Express the revenue R as a function of x. ​(c) Determine analytically the value of x for which revenue equals cost. ​(d) Graph y1equals​C(x) and y2equals​R(x) on the same​ xy-axes and interpret the graphs.

Answer:

(a)C(x) = 2500 + 3x

(b)R(x) = 5.5x

(c)x = 1000

Step-by-step explanation:

(a)His cost function as a function of x

C(x) = 2500 + 3x

(b)His revenue R function as a function of x

R(x) = 5.5x

(c)When revenue R equals to Cost C

C(x) = R(x)

2500 + 3x = 5.5x

2.5x = 2500

x = 1000

(d) Refer to attachment. We can see that the 2 lines intercepts at x = 1000 and y = 2500. That's the point of turning to profit.

Someone can help me Pleaseee
Morgarella [4.7K]

Answer:

a. Compressed f toward the x-axis, and then translated it left 4 units.

Step-by-step explanation:

General equation for this is:

 y = a√(x - h) + k

  • a is how much it's being compress or stretched
  • h is how much it's shifted in the x-direction
  • k is how much it's being shifted in the y-direction

We're given:

g(x) = 1/2√(x + 4)

g(x) = 1/2√(x - (-4))

My a-value is 1/2, so the original function f(x) is being compressed by 1/2 toward the x-axis.

My h value is -4 so it's being shifted by 4 units. It's shifted to the left because it's negative.

There is not k-value so nothing is shifted in the y-direction.

Explicit and Recursive Functions:

In this problem we need to find the value of a and b. So given that t<span>he function should be in the form f(n) = an + b and we know each value of n, then out goal is to find a and b.

For getting this purpose, we need to find a system of two equations (given that we have two unknown variables)

Therefore:

(1) f(0) = a(1) + b = 18
</span>∴ a + b = 18
<span>
(2) f(1) = a(2) + b = 24
</span>∴ 2a + b = 24<span>

Solving for a and b we have:

a = 6
b = 12

Finally:

f(n) = 6n + 12</span>

Roshanda was curious if students in her class would complete a maze faster if fast-paced music was playing in the background. Sh
ch4aika [34]

Answer: (E) Not necessarily, because this wasn't an experiment

Step-by-step explanation:

As much as the results would suggest that the fast-paced music was responsible for the faster finishing time, this conclusion cannot be authoritatively made because this was not technically an experiment but rather a test to satisfy curiosity.

An experiment is planned and is scientific. It has more stringent requirements that ensure causation that Roshanda did not meet before she engaged in this trial so we cannot say for a fact that her findings are objective.
