Question

It is known that a certain kind of algae in the Dead Sea can double in population every 2 days. Suppose that the population of algae grows exponentially, beginning now with a population of 1,000,000. (a) How long it will take for the population to quadruple in size?

Answer 1

Answer:

4 days

Explanation:

1,000,000*4=4,000,000(total size after quadrupling)

1,000,000*2=2,000,000(after 2 days.)

2,000,000*2=2,000,000(after 4 days.)

therefore it will take 4 days to quadruple in size
