Question
The number of units Q of a particular commodity that will be produced with K thousand dollars of capital expenditure is modeled by Q(K) = 500 K^2/3.
Suppose that capital expenditure varies with time in such a way that t months from now there will be K(t) thousand dollars of capital expenditure, where
K(t) = 2t4 + 3t + 149/ t + 2
(a) What will be the capital expenditure 3 months from now? How many units will be produced at this time?
(b) At what rate will production be changing with respect to time 5 months from now? Will production be increasing or decreasing at this time?
