At the beginning of 1990, 21.7 million people lived in the metropolitan area of a particular city, and the population was growing exponentially. The 1998 population was 26 million. If this trend continues, how large will the population be in the year 2011?

The population in 2011 will be of 34.88 million people.

Step-by-step explanation:

The population after t years is modeled by an exponential function is the following format:

In which P(0) is the initial population and r is the growth rate.

At the beginning of 1990, 21.7 million people lived in the metropolitan area of a particular city.

This means that

The 1998 population was 26 million.

1998 is 8 years after 1990. So

We use this to find the value of r.

So

If this trend continues, how large will the population be in the year 2011?

2011 is 21 years after 1990. So this is P(21).

The population in 2011 will be of 34.88 million people.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
