rates of change- population growth
The population of fish is modeled by the differential equation
dP/dt = 2p -0.01P^2
Where P is the nuber of fish after t years...
a) What is the maximum number of fish the tank can support ?
Ans : dP/dt= 0 hence P=0 or P=200 .... therefore @ P=200 its a maximum point...
b) Find P for which the population is increasing most rapidly... ?
Ans: I have no clue.. is it when d^2t/dP^2 =0 where there is a horizontal point of inflexion.. i.e when p=100 ??
can some one correct me on part b) ... Thanks :)
