Consider a Population P=P(t)P = P ( t ) With Constant Relative Birth and Death Rates

question 71

Short Answer

Consider a population P=P(t)P = P ( t ) with constant relative birth and death rates aa and β\beta , respectively, and a constant emigration rate mm , where α=0.8,β=0.7\alpha = 0.8 , \beta = 0.7 and m=0.5m = 0.5 . Then the rate of change of the population at time tt is modeled by the differential equation
dPdt=kPm\frac { d P } { d t } = k P - m
where
k=αβk = \alpha - \beta
Find the solution of this equation with the rate of change of the population at time t=6t = 6 that satisfies the initial condition P(0)=2900P ( 0 ) = 2900 .
