A model that describes the population of a fishery inwhichharvesting takes place at a constant rate is given by (dP/dt)= kP- h where k and h are positive constants. (a). Solve the DEsubject to P(0) = P0. (b). Describe the behavior of the populationP(t) forincreasing time in three cases P0>h/k P0=h/kand00 such that P(t) = 0. Ifthepopulation goes extinct then find T.
