A company manufactures nails that are meant to be precisely 10 cm long. The company devalues nails that differ in length from 10 cm. The amount a nail is devalued, in cents, is given by the function \(D(x)=6\sqrt{|x-10|}\), where \(x\) represents the nail’s length in centimeters and D represents the amount of the devaluation in cents. How much is a nail measuring 9.91 cm devalued?
