problem:
A pin is secured to the inside of the right front wheel of a car. This pin registers one unit on a counter with each complete revolution of the wheel. The counter connects to a timer and a transmitter. The transmitter sends the total count (the number of revolutions of the wheel) to a reader each second; the counter is then set back to 0. The reader converts each count into a recorded speed and displays the speed on a digital speedometer.
The wheel has a radius of 7 inches and the center of the wheel is 12 inches from the road surface.
a) Find a rule for a function that has as its input(domain) the real speed of the car and that has as its output (range) the count that would appear on the counter each second for a car traveling at that speed. Draw the graph of this function; limit the domain of your graph to the interval [50,60].
Please Help!
