Miguel Indurain, a five-time winner of the Tour de France, has the lowest recorded resting heart rate, 28 beats per minute (bpm). This is less than half the normal rate, which is about 66 bpm.
Which of the following equations, where t represents time in minutes and B the number of beats, represents a
heart rate greater than Indurain's?
Choose all answers that apply:
B = 2.8t
B= 20t
B = 27t
B = 297

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

a
