Final answer:
The equation N(t) = 450 models the number of people in a town who have heard a rumor after t days. As t increases without bound, N(t) approaches infinity. There is no limit to the number of people who have heard the rumor in the town.
Step-by-step explanation:
The equation N(t) = 450 models the number of people in a town who have heard a rumor 1 + 49e^(0.7t) after t days. As t increases without bound, N(t) approaches a specific value. This value can be found by taking the limit as t approaches infinity. In this case, the limit is found by evaluating the expression 49e^(0.7t) as t approaches infinity. Since the base of the exponential function (e) is a positive number greater than 1, the exponential function will approach infinity as t approaches infinity. Therefore, N(t) approaches infinity as t increases without bound.
Interpretation: As time goes on, the number of people who have heard the rumor will continue to increase without limit. This means that there will be no limit to the number of people who have heard the rumor in the town. It is not possible to determine the number of people who started the rumor based on the given equation.
