Suppose the population P of rainbow trout in a fish hatchery is modeled by the differential equation where P is measured in thousands of trout and t is measured in years. Suppose P(0) = 1. (a) How many trout are initially in the hatchery? trout. (b) Find a formula for the population at any time. P(t) = thousands of trout. (c) What is the size of the trout population after a very long time? lim P(t) = thousands of trout. 00+7 (d) At what time is the trout population increasing most rapidly? t = years. dP = P(6 - P), dt
