A bacteria culture grows with a constant relative growth rate. After 2 hours there are 600 bacteria and after 8 hours the count is 75,000.
(a) Find the initial population.
P(0) =
bacteria
(b) Find an expression for the population after t hours.
P(t) =
(c) Find the number of cells after 7 hours. (Round your answer to the nearest integer.)
P(7) =
bacteria
(d) Find the rate of growth after 7 hours. (Round your answer to the nearest integer.)
P'(7) =
bacteria/hour
(e) When will the population reach 200,000? (Round your answer to one decimal place.)
