Alright, I have my textbook in front of me now. It has what I drew, and it wants me to find the following:
a) Determine the rpm of the saw
b) Let L be the total length of the belt. Write L as a function of x, where x is measured in radians. What is the domain of the function? (Hint: Add the lengths of the straight sections of the belt and the length of the belt around each pulley)
c) Use the function from b to finish the table (Don't need help for this so long as there's an equation to use)
d) As x increases, do the lengths of the straight sections of the belt change faster or slower than the lengths of the belts around each pulley?
So apparently the value of x is unnecessary, but still needed as a group of values. Still unsure of what to do there.
