Suppose that the speed of a car, measured in miles per hour (mph), is monitored for some short period of time after the driver applies the brakes. The following table and graph relate the speed of the car to the amount of time, measured in seconds (sec), elapsed from the moment that the brakes are applied. ELAPSED TIME (sec) 2 4 6 8 10 SPEED of CAR (mph) 47 32 22 12 7 mph 30 40 30 20 10 12 What general trend do the data reflect? In which of the time intervals does the speed change the most? The table below shows lead emissions L in millions of metric tons from 1970 to 1990. Here tis years since 1970. 10 15 20 |199.1 143.8 68.0 18.3 5.1 Use exponential regression to find an exponential model for the data.
