If the world population is 7.0 billion in 2012, and the growth rate is constant at 1.4%, calculate the population in 2030. if the growth rate is constant for another 30 years, what will be the population in 2060

The world population in 2030 will be of 9.0062 billion.

The would population in 2060 will be of 13.71 billion.

Step-by-step explanation:

The exponential model for population growth is as follows.

In which P(t) is the population in t years from now, P(0) is the population in the current year and r(decimal) is the growth rate.e = 2.71 is the Euler number.

If the world population is 7.0 billion in 2012.

2012 is the initial year, so P(0) = 7.

P(t) will be measured in billions of people.

The growth rate is constant at 1.4%.

This means that

Calculate the population in 2030.

2030 is 2030-2012 = 18 years after 2012, so this is P(18).

So the world population in 2030 will be of 9.0062 billion.

What will be the population in 2060.

This is 2060-2012 = 48 years after 2012. So this is P(48).

The would population in 2060 will be of 13.71 billion.
