3. An altimeter is attached to a model rocket 5. The table shows the data for a before it is launched . The table shows the bouncing ball . recorded data from the rocket's flight. Bounce 3 Time (s) 5 6 Number Height (m) 230 310 0 350 360 350 300 220 Rebound Height (cm) 270 180 120 25 a) Make a scatter plot of the data . a) Make a scatter plot of the data . 6) Describe the relation . b) Describe the relation c) Draw a curve of best fit. c) Draw a curve of best fit. d) Use your model to predict the height d) How would the relationship change of the rocket after 8 s. for a ball that was bouncinr ? 4. The table shows the average fuel economy 6. Chapter Problem A city opened a new of a car at a test track landfill site in 2000 . The table shows Speed (km/h) Fuel Economy (L/100 km) how much garbage was added to the 10 14.26 landfill in each year from 2000 to 2007 20 12.85 Year Garbage Added (1000s of tonnes) 40 10.65 2000 200 60 10.10 2001 230 70 10.24 2002 258 80 10.84 2003 287 100 12.14 2004 317 120 15.64 2005 347 130 16.88 2006 376 150 22.50 2007 406 a) Make a scatter plot of the data . a) Determine the total mass of garbage b) Describe the relation . in the landfill at the end of each year. c) Draw a curve of best fit. b) Make a scatter plot of the total mass d) Use your model to predict the fuel of garbage versus the year. Draw a economy at 200 km /h. curve of best fit. e) This car does not get very good fuel c) What problems do you predict if economy. How would a graph of a car growth continues at its current rate ? with better fuel economy look ? Why ? 7. A rectangle has a width of x centimetres Did You Know ? and its length is double its width . New vehicles have an EnerGuide label that shows the city a) Create a table comparing the length and and highway fuel-consumption ratings and an estimated area of a rectangle for widths up to 8 cm. annual fuel cost for that vehicle. The fuel-consumption b) Make a scatter plot of the data . ratings are provided by vehicle manufacturers and are based c) Draw a curve of best fit. on standardized testing procedures and driving cycles performed under controlled conditions. d) Explain why the graph of this relation is non-linear
