Question 664121: if someone could help me that would be great! =)
the population of a bacteria colony starts at 100 & grows by 28% per hr.
a) find a formula for the number of bacteria P after t hrs
b) what is the doubling time for this population so how long does it take the population to double in size

thank you idk where to start....

the population of a bacteria colony starts at 100 & grows by 28% per hr.
After each hour, it's 1.28 times what it was.
-----
a) find a formula for the number of bacteria P after t hrs
P = 100*1.28^t, t in hours
-------------------
b) what is the doubling time for this population so how long does it take the population to double in size
200 = 100*1.28^t
1.28^t = 2
t*log(1.28) = log(2)
t = log(2)/log(1.28)
t =~ 2.808 hours
c) what is the continuous growth rate of the colony
