Question

A nation of 100 million people is growing at a rate of 5% per year. What will its population be in 20 years?

Calculate the doubling times found with the approximate and exact doubling time.

The approximate doubling time is years and the exact doubling time is years.

(Round to two decimal places as needed.)

Compare the doubling times found with the approximate and exact doubling time. Choose the correct answer below.

O A. The approximate doubling time is more than a year less than the exact doubling time.

OB. The approximate doubling time is more than a year greater than the exact doubling time.

OC. The approximate doubling time is less than the exact doubling time.

OD. The approximate doubling time is greater than the exact doubling time.

What will its population be in 20 years?

The population would be million people

(Round to the nearest integer as needed.)

Answer 1

Step-by-step explanation:

The doubling time is time it takes for a population to double in size/value. It is applied to population growth, inflation, resource extraction, consumption of goods, compound interest, the volume of malignant tumours, and many other things that tend to grow over time.

divide the number 70 by the percentage growth rate.
