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.

Solve for h.<br><br> –0.62 + 8.35 + 3.9h = –6.55 + 1.1h

stepan [7]

Answer:

$- 0.62 + 8.35 + 3.9h = - 6.55 + 1.1h \\ \\ 3.9h - 1.1h = - 6.55 + 0.62 - 8.35 \\ \\ 2.8h = - 14.28 \\ \\ h = \frac{ - 14.28}{2.8} \\ \\ h = \frac{ - 142.8}{28} \\ \\ h = - 5.1$

I hope I helped you^_^
