Problema Solution
Bacteria cultivated in a laboratoy have exponential growth. if a population of 500 bacteria increases to 900 after 1 hour how may bacteria are present after 7 hours?
Answer provided by our tutors
Solution:
Because the Bacteria have exponential growth
So the pupulation P(t) = P0*a^t
When t =1, a = 900/500 =1.8
So
P(7)/P0 = 1.8^7 = 61.22
So
P(7) = 61.22*500 = 30611
SO 7 hours later there are 30611 bacteria
