Consider a population P at time t with net relative growth rate k and constant emigration rate m. 2. a) Show that the time rate of change of P is modeled by the differential equation dP = kP – m dt where k and mare positive constants. b) Find the general solution of this differential equation, given that P = P, when (= 0. Show that c) (i) if m = kP, , then the population P(t) is constant (ii) for m > kP,, the population P(t) is declining.
