Question

It is estimated that the population of the world is increasing at an average rate of 1.09%. The population was about 7,632,819,325 in the year 2018. What equation represents the world population for t years after 2018? Group of answer choices

Answer 1

The equation that represents the population after T years is

`P_(t) = 7,632,819,325 [1 +(1.09)/(100) ]^(T)`

Explanation:

Population in the year 2018 ( P )= 7,632,819,325

Rate of increase R = 1.09 %

The population after T years is given by the formula

`P_(t) = P [1 +(R)/(100) ]^(T)` -------- (1)

Where P = population in 2018

R = rate of increase

T = time period

Put the values of P & R in above equation we get

`P_(t) = 7,632,819,325 [1 +(1.09)/(100) ]^(T)`

This is the equation that represents the population after T years.
