This poblem Involves bacteria...
there are initially 4000 bacteria per mililiter in a sample. after one hour their concentration increases to 6000 bacteria per mililiter.
a) what is the general exponetial equasion?
b) How many bacteria will there be after 2.5 hours
c) how many hours does it take to reach 8000 bacteria per mililiter.
so far i have isolated that the equasion N(t)=N e^kt is used to solve it
with N(t) being the final number
N being the initial number (4000)
k being a positive constant
and t being the number of hours
from here I have 6000= 4000 e^k*1
any help would be greatly apreciated thank you
