Question

the bacteria in a culture increases at the rate proportional to the number present at that time the number doubles in 10 years find the time in which the number becomes four times of the original number​

Answer 1

Answer:

32 times

Step-by-step explanation:

Let P0 be the initial population and let the population after t years be P. Then dP/dt = kP ⇒ dP/P = kdt On integrating, we have logP = kt + c At t = 0, P = P0 Therefore, logP0 = 0 + c. So, When t = 25h,
