Chapter 3.6, Problem 20PE
The populations of two countries are given for January 1, 2000, and for January 1, 2010.
a. Write a function of the form
b. Use the models from part (a) to approximate the population on January 1, 2020 for each country. Round to the nearest hundred thousand.
c. Israel had fewer people than Switzerland in the year 2000, yet from the result of part (b), Israel would have more people in the year 2020? Why?
d. Use the models from part (a) to predict the year during which each population would reach 10 million if this trend continues.

3. We'd like to know the first time when the population reaches 7000 people. First, graph the
function from part (a) on your calculator or Desmos. In the same window, graph the line y =
7000. Notice that you will need to adjust your window so that you can see values as big as
7000! Investigate the intersection of the two graphs. (This video shows you how to find the
intersection on your calculator, or in Desmos just hover the cursor over the point.) At what
value t> 0 does the line intersect with your exponential function? Round your answer to two
decimal places. (You don't need to show work for this part.) (2 points)

A house was valued at $95,000 in the year 1988. The value appreciated to $170,000 by the year 2007.
A) If the value is growing exponentially, what was the annual growth rate between 1988 and 2007?
Round the growth rate to 4 decimal places.
r =
B) What is the correct answer to part A written in percentage form?
r = 3
