general exponential models , where is the time from the starting moment and is some arbitrary base
if the count in a bacteria culture was after minutes,we have
............eq.1........solve for
..........eq.1a
if the count in a bacteria culture was after minutes,we have
............eq.2, sustitute
............simplify
then
..........eq.1a
if =>=>
general exponential models
What was the initial size of the culture?
the initial population "" was
The doubling period equation is
Find the population after minutes.
When will the population reach
