The total cost (in dollars) for a company to manufacture and sell x items per week is C(x)=50x+400. If the revenue brought in by

Vedmedyk [2.9K]

Answer:

$720

Step-by-step explanation:

Given the following functions

Cost function C(x)=50x+400

Revenue function R(x)=80x-0.05x^2

P(x)=R(x)−C(x).

Profit function P(x) = 80x-0.05x^2 - (50x+400)

P(x) = 80x-0.05x^2 - 50x - 400

Substitute x = 40

P(40) = 80(40)-0.05(40)^2 - 50(40) - 400

P(40) = 3200-80-2000-400

P(40) =3200-2480

P(40) = 720

Hence the amount of profit made is $720

Help look at picture!

Luda [366]

Answer:

Step 1: Set x to 0

$-2(0) + y = 3$

$y = 3$

(0, 3)

Step 2: Set x to 1

$-2(1) + y = 3$

$-2 + y + 2 = 3 + 2$

$y = 5$

(1, 5)

Step 3: Set x to 2

$-2(2) + y = 3$

$-4 + y + 4 = 3 + 4$

$y = 7$

(2, 7)

Step 4: Set x to 3

$-2(3) + y = 3$

$-6 + y + 6 = 3 + 6$

$y = 9$

(3, 9)

Answer:

$f(x)\rightarrow 1\ \text{as}\ x\rightarrow\pm\infty$

Step-by-step explanation:

"End behavior" generally refers to the behavior as the independent variable (x) gets large in the positive or negative directions. Here, the curve for large magnitude x flattens out and approaches 1. So, we say ...

$f(x)\rightarrow 1\ \text{as}\ x\rightarrow\pm\infty$
