Suppose a baby food company has determined that its total revenue R for its food is given by R = − x 3 + 39 x 2 + 945 x where R

Paraphin [41]

Answer:

35,000 units

Step-by-step explanation:

Total revenue is:

$R = -x^3+39x^2+945x$

The maximum revenue is attained at the production level for which the derivate of the revenue function is zero:

$R = -x^3+39x^2+945x\\R'=0=-3x^2+78x+945\\x=\frac{-b\pm\sqrt{78^2-(4*(-3)*945)} }{-6}\\x_1=35\\x_2=-9$

Since production cannot be negative, revenue will be at a maximum when x = 35, or when the production level is 35,000 units.

The length of a rectangle is 6 meters more than its width. If the area is 135 square meters, what is its width?

Novay_Z [31]

Length = width +6

L * (L - 6) = 135

L^2 - 6L = 135

L^2 - 6L -135 = 0

Length = 15
Width = 9
