The size P of a certain insects population at time t in days
     The size P of a certain insects population at time t (in days) obeys the function P(t) = 600.  (a) Determine the number of insects at t = 0 days.  (b) What is the growth rate of the insect population?  (c)What is the population after 10 days?  (d) When will the insect population reach 840?  (e) When will the insect population double?  (a) What is the number of insects at t = 0 days?  Insets 
  
  Solution
A) the number of insects at t =0 is 600
Since p(t) = 600e^0.07t = 600*e^0.07*0=600(1) =600
