You solve for them. That is why you are given two pieces of information.
y = Ce^kt
2 hours there are 600 bacteria
600 = Ce^k(2)
after 8 hours the count is 75,000.
75000 = Ce^k(8)
Use those two equations to solve for C and k.
1) A bacteria culture grows with constant relative growth rate. After 2 hours there are 600 bacteria and after 8 hours the count is 75,000.
a) find the initial population
b)find the rate of growth after 5 hours
I know that the formula is y = Ce^kt
how do i do this problem when im not given a K and i have to solve for C, the initial value..
