The tolerance in inches for the diameter of a piston is described by the absolute value inequality |d-5| , or equal to 0.01. What is the desired diameter of the piston? By how much can the actual diamer of the piston vary from the desired diameter?

|d-5} < .01
d-5 <.01 and d-5>-.01
d < 5.01 and d > 4.99
the desired diameter would be when |d-5| = 0
d = 5
