Math Problem Statement
The count in a bacteria culture was 200 after 20 minutes and 1900 after 35 minutes. Assuming the count grows exponentially, What was the initial size of the culture? Find the doubling period. Find the population after 120 minutes. When will the population reach 11000. You may enter the exact value or round to 2 decimal places.
