For a business using just-in-time inventory, a delivery of Q items arrives just as the last item is shipped out. Suppose that items are shipped out at a nonconstant rate such that $f(t)=Q-r \sqrt{t}$ gives the number of items in inventory. Find the time T at which the next shipment must arrive. Find the average value of f on the interval [0, T].

A manufacturer of lightbulbs wants to produce bulbs that last about 700 hours but, of course, some bulbs burn out faster than others. Let $F ( t )$ be the fraction of the company's bulbs that burn out before t hours, so $F ( t )$ always lies between 0 and 1. What is the meaning of the derivative $r ( t ) = F' ( t )$ ?
