A company manufactures industrial laminates (thin nylon-based sheets) of thickness 0.021 in., with a tolerance of 0.002 in

Question

(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.)

 

 

 

there should be 2 answers (a&b)

Answer 1

One way of reading the width and the tolerance is 0.021, plus or minus 0.0002 inches.

 

The range of widths is from 0.0210 - 0.0002 to 0.0210 + 0.0002.

 

0.0208 < h < 0.0212 inches.  (a)

 

Using interval notation,

 

[0.0208, 0.0212].  (b)
