The count in the bactoria culture blems (a) What was the initial size of the cuture? (b) Find the population after 95 minutes. (c) How many minutes after the start of the experiment will the population reach 13000 y Options tions as: Note: You can earn partial credit on this problem.

Explanation / Answer

P(t)=P0ekt

500=P0e10k

1000=P0e30k

Solving the above two equations, we get

a. Initial size, P0= 354 , k=0.035

b .P(95)=354e0.035(95)=9514

c .13000=354e0.035t

t=72 mins
