Question 1061954: The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate parameter of
9.3%
per hour. How many hours does it take for the size of the sample to double?
Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
let p be the population size, then
:
2p = p * e^(0.093 * t)
:
2 = e^(0.093 * t)
:
0.093 * t = ln(2)
:
Note use definition of logarithm
:
t = ln(2) / 0.093 = 7.4532
:

Population doubles in approximately 7.45 hours
