The following function gives the population of a town (in thousands of people), t years after it was founded: P(t) = 20(1 + e^{10-t})^{-1} What is the instantaneous rate of change of the population, 6 years after the town was founded? Choose 1 answer: A 0.06 people per year B 0.06 thousand people per year C 0.35 people per year D 0.35 thousand people per year

At a certain time (in years), the population (in thousands) of a small city is given by the function p(t) = 225 + (320t)/(t^2 + 15). Find the rate of change of the population after 6 years, rounded to 2 decimals.

The population of a town starts at 1,000 and doubles every decade. The graph below shows the growth in population of the town modeled by the function d=P, where P is the population in thousands and d is the time in decades. What is the approximate rate of change of the function over the interval 250 ≤ P ≤ 500?

Let $P(t)$ be the population (in millions) of a certain city $t$ years after 2015, and suppose that $P(t)$ satisfies the differential equation $$P^{\prime}(t)=.03 P(t), P(0)=4$$ (a) Use the differential equation to determine how fast the population is growing when it reaches 5 million people. (b) Use the differential equation to determine the population size when it is growing at the rate of 400,000 people per year. (c) Find a formula for $P(t).$
