One model of Earth's population growth is

P(t)=641+11e−.08t

, where t is measured in years since 1990, and P is measured in billions of people. Which of the following statements are true? Check all that apply.

AThe population of Earth is increasing by a steady rate of 8% per year.

BThe carrying capacity of Earth is 64 billion people.

CThe population of Earth will grow exponentially without bound.

DIn 1990, there were 5.33 billion people.

we are given the function adn we can see that when t is increased, P(t) is decreasing because of the negative sign. This means the value of the population which is the original of 64 billion will have to decrease.The answer that makes sense here is D. D. In 1990, there were 5.33 billion people.

The true statement is that; In 1990, there were 5.33 billion people.

What is an exponential function?

The term exponential function refers to a function which increases or decreases exponentially.

Let us consider the function, P(t)=641+11e−.08t; we can see that the true statement is that; In 1990, there were 5.33 billion people. This is because, the negative sign shows that the population of the earth is decreasing and there were more people in 1990 than there is today.
