The population of Cook island has always been modeled by a logistic equation P′=????(????−P) with growth rate ????=4 and carryin

g capacity ????=9000 with time t in years. Starting in 2000, 4 citizens of Cook island have left every year to become a mathematician, never to return.

Answer:

P = Ke^{(ln Pr^{c}-t) }

Step-by-step explanation:

The differential equation is modeled as follows:

P = r (C-P)

then

\frac{dP}{dt}  = r(C-P)

arranging gives:

dP = Cr - Pr

Arranging the equation gives:

\frac{dP}{P}  = \frac{C}{P}r - 1

solving:

P = e^{(lnPr^{c} -t)} K\\P = Ke^{(lnPr^{c} -t) }
