Running Speed Versus Length The table on the next page gives the length L, in inches, of an animal and its maximum speed R, in feet per second, when it runs. (For comparison, 10 feet per second is about 6.8 miles per hour.)
Animal | Length
|
Speed
|
Deermouse | 3.5 | 8.2 |
Chipmunk | 6.3 | 15.7 |
Desert crested lizard | 9.4 | 24.0 |
Grey squirrel | 9.8 | 24.9 |
Red fox | 24.0 | 65.6 |
Cheetah | 47.0 | 95.1 |
a. Does this table support the generalization that larger animals run faster?
b. Plot the data points.
c. Find the equation of the regression line for
d. Judging on the basis of the plot in part c, which is faster for its size, the red fox or the cheetah?

EBK FUNCTIONS AND CHANGE: A MODELING AP
- Power Consumption: The figure shows the power consumption in San Francisco for a day in September (P is measured in megawatts; t is hours stating at midnight). (a) What was the power consumption at 6:00 A.M? At 6:00 P.m.? (b) When was the power consumption the lowest? (c) Find the net change in the power consumption from 9:00 A.M. to 7:00 P.M/arrow_forwardAverage Speed A truck driver travels at an average speed of 55 miles per hour on a 200-mile trip to pick up a load of freight. On the return trip (with the truck fully loaded), the average speed is 40 miles per hour. What is the average speed for the round trip?arrow_forwardRunning Speed A man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runner’s time at the each of each lap, obtaining the data in the following table. (a) What was the man’s average speed (rate) between 68 s and 152 s? (b) What was the man’s average speed between 263 s and 412 s? (c) Calculate the man’s speed for cadi lap, Is he slowing down, speeding up, or neither?arrow_forward

It shows rates for 30-year fixed-rate mortgages since 1970. y=Year r=Mortgagerate 1975 9.05 1980 13.74 1985 12.43 1990 10.13 1995 7.93 2000 8.05 2005 5.87 2010 4.69 2015 3.84 a. Explain in practical terms the meaning of r(2003). b. Use the table to estimate the value of r(2003).arrow_forwardRunning Speed A man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runners time at the end of each lap, obtaining the data in the following table. aWhat was the mans average speed rate between 68 s and 152 s? bWhat was the mans average speed between 263 s and 412 s? cCalculate the mans speed for each lap. Is he slowing down, speeding up or neither?

Find the radius of the billiard ball.arrow_forwardLIFE SCIENCE APPLICATIONS Body Surface Area The surface area of a human in square meters has been approximated by A(h,m)=0.024265h0.3964m0.5378, where h is the height in cm and m is the mass in kg. Find A for the following data. Source: The Journal of Pediatrics. a. Height, 178cm; mass, 72kg b. Height, 140cm; mass 65kg c. Height, 160cm; mass, 70kg d. Using your mass and height, find your own surface area. e. f.arrow_forwardWork The work W required to lift an object varies jointly with the object’s mass m and the height h that the object is lifted.
