Question

The exponential model A=831.1 e^0.022t describes the population,A, of a country in millions, t years after 2003. Use the model to determine the population of the country in 2003

Answer 1

831.1 million

Explanation:

If the exponential model describes the population after 2003 and we must determine the population of the country in 2003 then t=0 because the time only starts after 2003:

`A=831.1\cdot{e^(0.022\cdot{0})}`

e to the power of 0 is equal to 1:

`A=831.1\cdot{e^(0.022\cdot{0})}=831.1\cdot{1}=831.1`

The population in 2003 is 831.1 million
