Question

Multiple Choice
The generation time G for a particular bacterium is the time it takes for the population to double. The bacteria increase in population is shown by the formula G = t over 3.3log 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 7525 bacteria? Round to the nearest hour.
A) 95 hours
B) 132 hours
C) 2 hours
D) 57 hours

Answer 1

I may be wrong but i say A my math is all over the place

Answer 2

your right (: thank you ! :)

Answer 3

No problem

Answer 4

I can't read the formula, but i guess that's okay since you got the answer :P

Answer 5

Sorry

Answer 6

Was it a guess? Because I don't see how you choose an answer w/o knowing what the formula is.

Answer 7

Well no i kinda know the formula but i solve it a different way then what i should have done and i don't want her to get confused on my way.

Answer 8

But you didn't show anything to show how you got the answer...

The formula, after plugging in given numbers, looks like this (but i'm not sure what the formula should look like, without seeing it)

4.5 = t over 3.3log 4 7525

Answer 9

Ya well sorry I didn't want to confuse her

Answer 10

But... Telling her the answer doesn't help her to learn how to do it :P
