A number changed to 12.6 after it was rounded. To what place was the number rounded? Explain how you know.

Anton [14]

If 12.6 was rounded, that means that it was rounded to the tenths place.
You know this because the number has one decimal place, so that must be what it was rounded to.

The human population of the earth can be modeled by p(T)=3.1(1.016)^t , where T represents the number of year since 1963 , and p

Mkey [24]

Answer:

See below

Step-by-step explanation:

Given function:

p(t)=3.1(1.016)^t

The base of the growth rate is:

1.016 = 1 + 0.016

It represent a 1.6% of growth per year.

Increasing

p(55) = 7.42 means:

55 years after 1963, in the year 2018, the population of Earth is 7.42 billions
