the size P of a certain insect population at time T (in days) obeys the function P(t)=900e^0.04t
A) number of insects at t=0 days.
B)What is the population after 10 days
C) when will the population reach 1260?
To learn how to do this on your own:
They have given you a formula for the number P at time t (not "T"), and have here given you a value for t and have asked for the number P. So plug the number in for t, and simplify to find the value of P.
You are given a value of 10 for t, and asked for the value of P. So plug the number in for t, and simplify to find the value of P.
They have given you a value for P and asked for the time t. So plug the value in for P, and solve the resulting equation for the value of t.
