A population of kangaroos is growing at a rate of 2% per year, compounded continuously. If the growth rate continues, how many y
antoniya [11.8K]

Answer:

The correct answer is 20 years.

Explanation:

It is given that the growing rate is 2% or 2/100 = 0.02

This rate got increased to 150%

The formula for exponential growth is:  

A = Pe^rt

Let the initial population be 100%

150 = 100.e^0.02*t

3/2 = e^0.02t

1.5 = e^0.02t

After taking log from both the sides:  

ln(1.5) = 0.02t * ln(e) [ln(e) = 1]

ln(1.5) = 0.02t

t = ln(1.5)/0.02

t = 20.27

Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.
