One model of Earth's population growth is P(t)= 64/(1+11e^0.8t)
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.

A. In 1991, there were 5.74 billion people, according to this model.

B. The population of Earth will grow exponentially for a while but then start to decrease.

C. The population of Earth is growing at a rate of just under 8% per year.

D. The carrying capacity of Earth is 64 billion people.

The total population in 1991 were 5.74 billion and the population grow exponentially but then start decreasing so option (A) and (B) both will correct.

What is a function?

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

Given that the expression P(t)= 64/(1+11[tex]e^{0.8}[/tex]t)

if you put t =1 for the year 1991 then it comes out to be around 5.74 billion.

And if you look at the nature of this graph then it will grow exponentially for a while but then start to decrease.

Hence A and B both will be correct.
