Question

Last question of the day!! Please help me!?!
The generation time G for a particular bacteria is the time it takes for the population to double. The bacteria increase in population is shown by the formula G= (t)/(3.3log(base a)P)
where t is the time period of the population increase, a is the number of bacteria at the beginning of the time period, and P is the number of bacteria at the end of the time period. If the generation time for the bacteria is 4.5 hours, how long will it take 4 of these bacteria to multiply into a colony of 7,525 bacteria? Round to the nearest hour.

Answer 1

A. 95 hours
B. 132 Hours
c. 2 hours
D. 57 hours

Answer 2

OK, you know that in 6 hours they will double. Take the log base 2 of 7681 and subtract the log base 2 of 8 (which is three) and you know how many doublings there are. Then, multiply that by 6 hours.

Answer 3

Okay, I got that wrong. I had the wrong quiz. But it should still be the same.

Answer 4

Same basic concept, yes.

Answer 5

Thanks so much!
