Question

Suppose that the number of bacteria in a certain population increases according to an exponential growth model. A sample of bacteria selected from this population reached the size of bacteria in three hours. Find the continuous growth rate per hour.


Write your answer as a percentage. Do not round any intermediate computations, and round your percentage to the nearest hundredth.

Answer 1

P = P(%) e^(3r) maybe

Answer 2

whole = sample e^(3r)

whole
----- = e^(3r)
sample

ln(w/s)
------ = r ; might want to throw on a constant of variation ???

Answer 3

this is hard to parse:

"A sample of bacteria selected from this population reached the size of bacteria in.."
