A company manufactures industrial laminates thin nylonbased

A company manufactures industrial laminates (thin nylon-based sheets) of thickness 0.023 in., with a tolerance of 0.001 in.

(a) Find an inequality involving absolute values that describes the range of possible thickness for the laminate. (Use h for the thickness.)


(b) Solve the inequality that you found in part (a). (Enter your answer using interval notation.)

Solution

theickness = 0.023 inch

Tolerance = + /- 0.001 inch

So, maximum thicknes = 0.023 + 0.001 = 0.024 inch

Min. thickness = 0.023 -0.001 = 0.022

So,Let the theickness be h

Inequaltity defining thickness :

0.022<= h < 0.024

b) h = [ 0.022, 0.024]
