<PRE><B>Question 1028763</B>
For a certain strain of bacteria, the number of bacteria present after t hours is given by the equation
Q = Qo*e^(0.23t_
where Qo represents the initial number of bacteria. How long will it take 600 bacteria to increase to 6000 bacteria?
------
6000 = 600*e^(0.23t)
----
e^(0.23t) = 10
------
0.23t = ln(10)
------
t = ln(10)/0.23
------
time = 10.01 hours
