A car tire is spinning a complete revolution every 0.60 seconds. The valve stem is 2 inches above ground at its lowest point and 26 inches at it's highest. Describe the height of the valve stem as a function of time (seconds) if it begins at the bottom.

Answer:

Step-by-step explanation:

What is the amplitude, ||, of the height and co-height functions for this car tire

|| = 6

Let () represent the co-height function after rotation by radians, and let () represent the height function after rotation by radians. Write functions for the co-height and for the height in terms of .

() = ()

() = ()  

The co-height graphs are the same but translated 2 inches upward

so our function is:

() = ()  + 2 or

() = ()  + 2
