At Orange County Choppers, Paul Teutul Junior needs to make a circular metal disk with area 1100 in². 0₁ The radius of such a disk is To keep Paul Senior from blowing a gasket, Paul Junior must deviate from the ideal area of the disk, which is 1100 in², by less than ±5 in². Let a be the actual radius of the disk and f(x) the actual area of the disk. What is the formula for the function f(x)? inches. What is the number represents the target input? What is the number represents the target output? What value of output tolerance, or €, is given? What is the smallest acceptable radius? What is the largest acceptable radius? What is the corresponding value of the input tolerance, or d? How close to the ideal radius must the Flowjet (the machine that cuts the disk) be to maintain tranquility at OCC? Answer= inches.
