The population of a region is growing exponentially. There were 10 million people in 1980 (when t= 0) and 60 million people in 1990. Find an exponential model for the population (in millions of people) at any time t, in years after 1980. (Note: if you use decimal approximations for the mumerical constants in your work, be sure to retain enough significant figures through your work to ensure that subsequent answers are correct.) P(t)= What population do you predict for the year 2000? Predicted population in the year 2000 = million people. What is the doubling time? Doubling time = years.

The population of a region is growing exponentially. There were 10 million people in 1980 (when t= 0) and 60 million people in 1990.
Find an exponential model for the population (in millions of people) at any time t, in years after 1980.
(Note: if you use decimal approximations for the numerical constants in your work, be sure to retain enough significant figures through your work to
ensure that subsequent answers are correct.)
P(t)=
What population do you predict for the
Predicted population in the year 2000 =
year 2000?
million people.
What is the doubling time?
Doubling time :
years.
