For a certain company, the cost function for producing x items is C(x)=30x+150 and the revenue function for selling x items is R

olga55 [171]

Profit, revenue and cost are related, and can be calculated from one another.

The profit function is $\mathbf{P(x) =-0.5(x -90)^2 - 30x + 3900}$
The domain of the profit function is x > 0
The profit when producing 60 items is 1650
The profit when producing 70 items is 1600

The cost function is given as:

$\mathbf{C(x) =30x + 150}$

The revenue function is given as:

$\mathbf{R(x) =-0.5(x -90)^2 + 4050}$

(a) Calculate the profit function

This is calculated using:

$\mathbf{P(x) = R(x) - C(x)}$

So, we have:

$\mathbf{P(x) =-0.5(x -90)^2 + 4050 - 30x - 150}$

Evaluate like terms

$\mathbf{P(x) =-0.5(x -90)^2 - 30x + 3900}$

(b) The domain of the profit function

When profit is 0 or less, then it becomes no profit.

Hence, the domain of the profit function is x > 0

(c) The profit for 60 and 70 items

Substitute 60 and 70 for x in P(x)

$\mathbf{P(60) =-0.5(60 -90)^2 - 30 \times 60 + 3900}$

$\mathbf{P(60) =1650}$

The profit when producing 60 items is 1650

$\mathbf{P(70) =-0.5(70 -90)^2 - 30 \times 70 + 3900}$

$\mathbf{P(70) = 1500}$

The profit when producing 70 items is 1600

(d) Why producing 10 more units less profit

When a function reaches the optimal value, the value of the function begins to reduce.

This means that, producing 10 more units takes the profit function beyond its maximum point.

Y=f(x)=(-3)^x find f(x) when x=0

chubhunter [2.5K]

This one would be just 1, because any number that had 0 as an exponent would result in 1.

Margie has a $50 budget to purchase a $45 pair of boots if there is an 8% sales tax rate then how much under budget will Marjori

Lynna [10]

Boots + (Boots * Tax %) < $50 budget

$45 + ($45 * 8%) < $50
45 + (45 * 0.08) < 50
45 + 3.60 < 50
48.60 < 50

Subtract the total boot cost from the total budgeted amount.

= 50 - 48.60
= $1.40 under budget

ANSWER: She will be $1.40 under budget.

Hope this helps! :)
