b. Find an exponential regression equation that models this situation (Round to the nearest hundredth). Reminder: this will be listed under Epreg in the [STATHCALC] eld in your calculator. You might want to review regression from lesson 11. c. What is the value of the exponential appreciation rate? 8. if a car is traveling at 65 MPH, calculate how many feet per second this equals. (Round to the nearest tenth) 9. Cedric is driving at 38 MPH on a one-lane gravel road. He must make a quick stop because he sees a cow in the road ahead. a. What is his approrrimate reaction distance? b. What is his approximate braking distance? c. About how many feet does the car travel to come to a complete stop when he rst sees the cow? 10. The following measurements from yaw marks left at the scene of an accident were taken by authorities. Using a 31ft length chord. the middle ordinate measured approximately 3 ft. The drag factor for the road surface is 1.02. Project 3 331 MTHH 04? a. Determine the radius of the yaw mark to the nearest tenth of a tool. b. Determine the minimum speed that the car was going when the skid occurred to the nearest tenth. Thle project can be submitted electronically. Check the instructions In the online course for more Information. Project 3 332 MTHH 047 7. The July 2008 issue of Hemmings Motor News included a feature story on the 1957 Cadillac Eldorado Brougham. When sold as a new car in 1957. the price was $13,074. It depreciated over the next few years. Then. in 1967. something interesting began to happen as seen in this table of values. 8. Construct a scatterplot on your calculator for the data. Let 1967 be year 1. 1977 be year 11. 1937 be year 21 . and so on. What do you notice about the trend? Project 3 380 MTHH 047
