The population of a town grows at a rate of r(t) people per year (where t is time in years). At t=3, the town's population was 1000 people.What does 1000+∫38r(t)dt=1500 mean?Choose 1 answer:(A) The town's population grew at a rate of 1500 people per year at t=8.(B) The town's population grew by 1500 people between t=3 and t=8.(C) The average rate at which the population grew between t=3 and t=8 is 1500 people per year.(D) At t=8, the town's population was 1500 people.
Q. The population of a town grows at a rate of r(t) people per year (where t is time in years). At t=3, the town's population was 1000 people.What does 1000+∫38r(t)dt=1500 mean?Choose 1 answer:(A) The town's population grew at a rate of 1500 people per year at t=8.(B) The town's population grew by 1500 people between t=3 and t=8.(C) The average rate at which the population grew between t=3 and t=8 is 1500 people per year.(D) At t=8, the town's population was 1500 people.
Evaluate Integral Meaning: Evaluate the meaning of the integral in the context of population growth. The integral ∫38r(t)dt represents the total change in population from time t=3 to t=8.
Interpret Equation: Interpret the equation 1000+∫38r(t)dt=1500. The initial population at t=3 is 1000 people. The integral adds the total population change from t=3 to t=8 to this initial population. The result, 1500, is the population at t=8.
Determine Correct Answer Choice: Determine which answer choice correctly describes the equation.(A) Incorrect - The equation does not describe the rate of population growth at t=8.(B) Correct - The equation indicates that the population grew by 500 people (1500−1000) between t=3 and t=8.(C) Incorrect - The equation does not provide information about the average rate of growth.(D) Incorrect - The equation states that the population is 1500 at t=8, not that it grew by 1500 people.
