Using absolute value, it is found that:
- The situation is described by the following equation: [tex]|l - 47| = 1.5[/tex]
- The markings should be between 45.5mm and 48.5mm.
---------------------------
The definition of the absolute value function is as follows:
[tex]|x| = x, x \geq 0[/tex]
[tex]|x| = -x, x < 0[/tex]
----------------------------
The length should be set to 47mm with an allowance of 1.5mm, which means that the absolute value of the difference between the length and 47 should be 1.5, thus:
[tex]|l - 47| = 1.5[/tex]
----------------------------
The solutions are:
[tex]l - 47 = -1.5 \rightarrow l = 45.5[/tex]
[tex]l - 47 = 1.5 \rightarrow l = 48.5[/tex]
The markings should be between 45.5mm and 48.5mm.
