The number of fish tripled in the first year. [SCalcCC2 7.5.08.] (a) Assuming that the size of the fish population satisfies the logistic equation, find an expression for the size of the population after t years. P(t) = 10000/(1+A*e^(-1.5*t)) [10000/ (1+24*(11/36)^t)] (b) How long will it take for the population to increase to 5000? 10.593 [2.68] years Home My Assignments ...
