The count in a bacteria culture was 800 after 10 minutes and 1500 after 40 minutes. Assuming the count grows exponentially,

What was the initial size of the culture? __________________________

Find the doubling period?______________________

Find the population after 75 minutes?________________________________

.

When will the population reach 13000? _________________________________

You may enter the exact value or round to 2 decimal places.
