Australia experienced approximately linear population growth from 1960 to 2010. On the other hand, Afghanistan was torn by warfare in the 1900s and did not experience linear or near-linear growth.1 Year 1960 1970 1980 1990 2000 2010 9.00 11.12 13.21 12.07 19.70 27.96 Population of Country A Population of Country B 10.29 12.90 / 14.71 17.10 19.11 22.16 (a) The table above gives the population of these two countries, in millions. Which of these two countries is A and which is B? Explain. The population of Country A m at an approximately constant rate. Thus, Country Ais The population of Country B at an approximately constant rate. Thus, Country B is The population of Country B at an approximately constant rate. Thus, Country B is (b) What is the approximate rate of change of the linear function? What does the rate of change represent in practical terms? Round your answer to two decimal places. Approximate average rate of change = i The rate of change tells us (c) Using the value from part (b), estimate the population of Australia in 1998. Use the closest date before 1998 as the starting point. Round your answer to one decimal place. million people. The population of Australia in 1998 was approximately i cion 19 of 50 ne table above gives the population of these two countries, in millions. Which of these two countries is in. opulation of Country A at an approximately constant rate. Thus, Country A is opulation of Country B did change at an approximately constant rate. Thus, Country B is did not change That is the approximate rate of change of the linear function?
