In 2010, (when t = 0), the population of a country was 1.16 billion people and increasing at a rate proportional to its population. If the population is measured in billions of people and time is measured in years since 2010, the constant of proportionality is 0.0138.

(a) Define the variables.

Let P be the population, in trillions of people, in year t, where t represents the number of years before 2010.

Let P be the population, in billions of people, in year t, where t represents the number of years before 2010.    

Let P be the population, in billions of people, in year t, where t represents the number of years since 2010.Let P be the population, in billions of people, in month t, where t represents the number of years before 2010.

Let P be the population, in billions of people, in year t, where t represents the current year.

dP
dt

=

with initial condition P(0) = _____________

(c) Solve the differential equation.
P = _________________________

Scientists often use a different function to model population growth when there are limited resources, as is the case with our planet. To do this, we will model the world population (in billions of people) in year t by the function L(t) = P0K / P0 + (K − P0)e-rbt , where P0 and...
