Answer:
4 square root of 5
Step-by-step explanation:
The exponential growth rate is approximately 1.56% per year for a population to double in 45 years.
To calculate the annual growth rate for a population that doubles in a specific time period, we can use the rule of 70, which is a formula for estimating the time it takes for an investment or population to double given a constant growth rate. The rate of growth (r) can be calculated as r=70/t, where t is the time in years.
In this case, the country's population doubled in 45 years. So, the annual growth rate would be r=70/45
= 1.56%.
Therefore, the exponential growth rate that caused the country's population to double in 45 years is approximately 1.56% per year.
