Question:

When a reservoir is created by a new dam, 50 fish are introduced into the reservoir, which has an estimated carrying capacity of 8000 fish. A logistic model of the fish population isimagewhere t is measured in years.


a. Graph P using a graphing utility. Experiment with different windows until you produce an S-shaped curve characteristic of the logistic model. What window works well for this function? 


b. How long does it take for the population to reach 5000 fish? How long does it take for the population to reach 90% of the carrying capacity?c. How fast (in fish per year) is the population growing at t = 0? At t = 5?d. Graph P' and use the graph to estimate the year in which the population is growing fastest.
