MEDAL!!!

A biologist is researching a newly-discovered species of bacteria. He puts 1,000 bacteria into what he has determined to be a favorable growth medium. Twelve hours later, he measures 12,500 bacteria. Assuming exponential growth, find the growth equation and use it to determine the number of bacteria after twenty hours.
A. 20,167
B. 20,864
C. 67,326
D. 78,324

@trantom I got B as my answer, is that correct?

trantom · Answer

First of all, in rebuke to my common but unexpected absences, I have a cold and am drinking a lot of water and thereof travel to the lavatory quite often.
Second, in answer to your third question of which I have graciously replied, may I inquire the specific "growth equation" thee hath useth?

anonymous · Answer

lol huh?

trantom · Answer

what is your growth equation XD

anonymous · Answer

A = 1000e^(20*0.2148)

trantom · Answer

meh why exponential growth xD so you mean A = 1000 x 10^4.296?

anonymous · Answer

yea, from what im getting

trantom · Answer

I don't think it can be a or b because it says exponential and a and b don't even add as much as the first 12 hours did.

trantom · Answer

I think it's C but it could be D... its not a or b though I know that

anonymous · Answer

its c:)
