Let C(x) be the cost to produce x batches of widgets, and let R(x) be the revenue in thousands of dollars. R(x) = − x² + 6x, C

Musya8 [376]

Answer:

Step-by-step explanation:

Let C(x) be the cost to produce x batches of widgets, and let R(x) be the revenue in thousands of dollars.

$R(x) = -x^2 + 6x,\\ C(x) = x + 4.$

Profit function = Revenue - cost

So we get profit function by subtracting C(x) from R(x) using algebraic method of subtraction.

Profit function of x

= $Pr(x) = R(x) -C(x)\\= -x^2+6x-x-4\\=-x^2+5x-4$

AleksandrR [38]

Answer

given,

pears that weighs 6.78 pounds.

statement

$1.41 (6.78) - $1 * 7 = $7

on solving the left hand side of the statement

$1.41 (6.78) - $1 * 7 = 9.5598 - 7

= $ 2.5598

Left hand side and right hand side is not equal

the estimate is wrong

the exact product is equal to $ 2.5598

so, we can say that the exact product is less than $7
