Biologists have stocked a lake with 1,000 trout. They estimate that the maximum capacity for this lake is 5,000 trout. After 4 years, they noticed that the trout population had quadrupled.

(i) Assuming the population conforms to the logistic model, calculate its relative growth rate k for an unconstrained environment.

k= (round out the number to 3 decimals)

(ii) Aprs combien d'annes y avait-il 3,0003,000 truites dans le lac?

Answer =

years. (round out to 2 decimals)
