Question

A population of bacteria is growing according to the function below, where t is in hours. How many hours will it take for the population to grow to 1,000 bacteria? Round your answer to the nearest integer. Do not include units in your answer.

Answer 1

\[B(t) = 50 \times e ^{2.5t}\]

Answer 2

So 1000 = 50e^2.5t

e^2.5t = 20 and ln both sides to find t

Answer 3

1.1982= 1?

Answer 4

yes (I assume you mean 1.19 rounded to nearest integer is 1)
