Look on the given website (https://www.worldometers.info/world-population/) under the "Growth Rate"heading to find the current growth rate of the world's population. Note that this is the growth rate r,and you will need to convert it from a percentage to a decimal before you use it in your model.Since the population in the year 1800was just under 1billion,use 1as your starting population (in billions)in 1800.

Write the exponential model P, where t is years since 1800and P is the population in billions, using the growth rate and starting population.

P =______(_________)^t
