A red car moving at 44.7 mph passes a blue car moving at 30.7 mph. (Use 1609 meters = 1 mile when converting to meters/second.) Seeing a stopped car in his lane up ahead, the driver of the red car applies the brakes just as he passes the blue car which causes the red car to slow down to a stop by losing 4.36 m/s every second.

(a) How much time (in seconds) passes before the two cars are side-by-side once again?
s




(b) When the cars are finally side-by-side, how do their average speeds compare for the time you calculated above? Please explain fully.

I really don't understand this concept....all I know is that it has to be written in interval notation...so for example, here is one problem:

f(x)= x/x^2+2x+4

How would I find the domain and range????!!? If anyone could give me an explanation as to how they are found, and WHY they are found, and a method in finding them it would be greatly appreciated!

I have a friend who is now on probabtion, part of his probation stipulations is no alcohol consumption, accompaning random alcohol testing. Is there anyway to rid your system of alcohol so that it is undetectable by a breathalizer or urine test? I know that this is a dumb question, I had to ask however.
