The number of individuals N in a population of a certain species is given by the following function of time, t:
N(t)= 100/(1+9e^t), t>=0
a.)how many ppl are in the population initially(at t=0)
b.)determine the size ofa the populations as tgoes towards infiniti?
c. what is the growth rate of the pop. at time t? what is the growth rate at t=0?

A 100/(1+9*1)=10
b lim as t>infinity is 100
c the growth rate at time 0 is 9
