Question

A= pe^rt formul

the population on island x in year 2000 is 10 million, and was 16 million in 2015 find the doubling time of the population

Answer 1

16 = 10e^5r

1.6 = e^5r

ln 1.6 = 5r

0.47000 ≈ 5r

0.09400 ≈ r

 

0.5a₀ = a₀e^0.09400t

0.5 = e^0.09400t

ln 0.5 = 0.09400t

 

Can you solve for t and answer?
