The population of a region is growing exponentially. There were 35 million people in 1980 (when t=0) and 70 million people in 1990.

Find an exponential model for the population (in millions of people) at any time t, in years after 1980. 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 the world was about 5.3 billion in 1990 (t = 0) and about 6.1 billion in 2000 (t = 10). Assuming that the carrying capacity for the world population is 50 billion, the logistic differential equation dP =kP(50−P)dt models the population of the world P(t) (measured in billions), where t is the number of years after 1990. Solve this differential equation for P(t) and use this solution to predict what the population will be in 2050 according...
