Alright, my teacher the sadist gave us an assignment over the holidays, and so far, everyone in my class has gotten all but this. The equation is representative of the population growth of fish in a fish pond. p= m / 1+ae to the -kt p is the intial population, m the carrying capacity of the pond, t is time, k is a constant of 0.9, and nobody knows what a is. The question is basically, is a a constant, or what? I'm not worried about solving everthing, just whether a is a constant, or whatever, I think a is the number of additional fish every year, but I'm not sure. If it's any help, I've found the carrying capacity to be 53869 fish, and the intial population is 1000.
