Hey everyone, I have a question about hair strand drug testing... Here we go:

I have to take a hair strand drug test to be hired on for a position with a well known insurance company. I will be working in the Federal Employee center, working with people who are federal employees that have insurance with the company. It is a government position.

In the past I have smoked minimal amounts of marijuana and taken some muscle relaxers here and there... It has been quite some time since I have done this.

I have heard that the longer your hair, the farther back they can test, (I have long hair) but how far back do they actually test for employment?

I want to know how far back they test for drugs, and what type of drugs they test for.


Thanks In Advance :)

Some students simplify

2x^2 - 32 / x - 4
as
2x - 8
Choose values of x to show this is not true. Then simplify it correctly.

Thanks for the help.

We can only trace the history of the universe back to the big bang, prior to that there was no time, space or matter. What started it, where did it come from? Who made God? Most importantly, how many licks does it take to get to the center of a tootsie roll tootsie pop? And does knowing or not knowing benefit mankind more?

I'm not sure how to solve for a variable if it is in both the numerator and the denominator.
For example: Solve for y, x=(y+2)/(5y-1)

If you could show how to solve this it would be really helpful. Thanks in advance!

I am having some problems trying to find the inverse formula for this function:

y = (1 + e^x)/(1-e^x).

I was trying to use natural log and ended up here:

ln(y) = (1+x)/(1-x) ----> I am unsure of where to proceed from here.

I am having problems memorizing my multiplication tables for 4th grade. I am very smart and one of top students in my class in all areas except for this one. For some reason I just can't make it stick. I have tried most common methods such as flash cards, games etc.

Does anybody have some different methods or tricks for memorizing.
