neil was growing a culture of bacteria for a biology experiment. he noticed that the population doubled after 90 minutes. if the population grows exponentially, how many times the original population will there be after six hours?

Answer 1

Looks like base 2 numerals:

90min. = 1.5h,

6h / 1.5h = 4.

Po = 2^0 = 1 = Initial pop.

P = 2^4 = 16 times Po.
