The specifications for machined parts are given with tolerance limits. For example, if a part is to be 6.8 cm thick, with a tolerance of .01 cm, this means that the actual thickness must be at most .01 cm, greater than or less than 6.8. Between what two thicknesses is the dimension of the part accceptable? Write an absolute value equation using "d" as the variable. Write, as well, the set notation, and interval notation that models this situation and discuss the difference in what absolute value notation shows as opposed to set and interval notations.

One reason it's nice if someone includes whatever work they've already attempted on a problem is to find out where you are having the difficulty. This has several steps - where are you confused?

For instance, do you already have the acceptable range? Do you have any other parts done? Do you not know how to start it?

Hi, LaneyLynnM!

This isn't a site where people simply "plug" in their homework questions and get automatic answers. If that happened, how would that be helping the students to learn how to come up the correct answers on their own?

What I would suggest that you do, is to show on this thread, how you're trying to solve the question. If you do that, you'll be more likely to have someone come along who'll be able to help you to figure out how to come up with the correct answer on your own.

I also want to refer you to the announcement about getting homework help on this site, that can be found via clicking on the following link.

Hi, morgaine300!

Looks like I was formatting my answer while you were posting yours!

Thanks!

Occupational hazard. :-)

Probably so... :)
