The count in a bacteria culture was 400 after 15 minutes and 1200 after 35 minutes. Assuming the count grows exponentially, What was the initial size of the culture?    Find the doubling period.    Find the population after 80 minutes.    When will the population reach 10000.    You may enter the exact value or round to 2 decimal places.

Q: Because of a virus introduced into a bacterial culture, the population of the bacteria decreased…

A: Exponential decay is N = 50000e-λt Therefore, 30000 at t= 54 min Therefore 30000 = 50000e-λ54…
