5.1.3 Rate of Change and Slope - Practice
1. The table shows the deer population in a forest over a 15-year period. Year 1 4 7 11 15 Population 50 100 150 250 300 Complete the following table by finding the rate of change in the population for each time interval (to the nearest hundredth). Year 1-4 4-7 7-11 11-15 Rate of Change During which time interval did the population increase at the greatest rate? 3. The table shows the height of a lake in different years. Graph the data from the table and show the rates of change from 2-4 years and 4-5 years. Number of Years 2 4 5 Height (feet) 100 80 50
2. The table shows the number of toys sold at a game store in different years. Year 1990 1993 1995 2000 2006 # of Toys Sold 20,000 32,000 42,000 57,000 63,000 Complete the following table by finding the rate of change in the number of toys sold for each time interval.
1990- 1993
1993- 1995
1995- 2000
2000- 2006
