Question

anonymous · Answer

A quality control inspector is in charge of inspecting drill bits that are produced on an assembly line. The diameter of a drill bit can be modeled by the equation |x − 0.525| = 0.01. Show your work in solving the equation to determine the minimum and maximum diameters of the drill bits.

anonymous · Answer

You sure it's a equal sign and not a  < sign?

unklerhaukus · Answer

consider two cases
I
 (x − 0.525) = 0.01
II
 -(x − 0.525) = 0.01

anonymous · Answer

If so, you need to functions, one explain the range of x when x<0.525, and one when x> 0.525,

anonymous · Answer

so how do i solve this?

unklerhaukus · Answer

take one case at a time, solve for x

anonymous · Answer

i tried that, but im so confused im not getting it

unklerhaukus · Answer

lets look at the first case
I
 (x − 0.525) = 0.01
  x − 0.525  = 0.01

add  0.525 to both sides of the equation 

                    =

anonymous · Answer

x − 0.525 - 0.0525 = 0.1, right?

anonymous · Answer

No, there are  two equations.

One is x-0.525=0.01

The other one is 0.525-x=0.01

You are expected to get two values of x, hence the two equation.

anonymous · Answer

second one? x=0.0425
0.0425 - 0.0525 = -0.01, |-0.01|=0.01

anonymous · Answer

i have no idea where 0.0525 come from... also. The absolute value is the reason we divided the original equation into two, you don't need to apply it again.
Do you know why?
