Suppose the population of a small town is 567 in 2011. the population decreases at a rate of 1.5% every year. what will be the population of the town in 2020? round your answer to the nearest whole number.

Using an exponential function, it is found that the population of the town in 2020 will be of 495.

A decaying exponential function is modeled by:

In which:

In this problem:

Then:

2020 is 9 years after 2011, hence:

The population of the town in 2020 will be of 495.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
