Consider a cube composed of (n^2) unit cubes. If we paint the surface of the composed cube, some of the unit cubes may have no sides colored and some may have more than one side colored. Using (n), classify the cube breaking down how many of each type of unit cubes there are.


NOTE: You have two jobs. The first is to consider different sized cubes, such as for n=1,2, etc. Next for each of these sizes give the categories determined by the unit cubes and determine the number of unit cubes in each category.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Show the solution...

Nature can be awsome in the truest sence. Powerful, dangerous and beautiful. Have you ever been caught in the cusp between safety and danger in the face of something so beatuiful, it was hard to tear yourself away. What did you see, where was it and what happened.

"Define variables and write a function that describes each situation.

a. You drive on an interstate highway with your cruise control set at 65 MPH and do not need to stop or alter your speed.

b. You rent a small moving van to move your belongings to your new apartment. The rental company charges $45 a day plus $0.22 a mile to rent the van."

Please explain too.. thanks!

I know two equations which I was told to use to find the half life. But I am lost as to how I have to use them. So if someone knows the answer or just how to solve this please help. Thanks.

Lortab contains gydrocodone which is a powerful pain killer. The half life of hydrocodone is about 5 hrs, so half of the drug will be out of your system in 5 hrs. Half of the half will be out in another 5 hrs.
If you take 10mg of Lortab, how many days will it take until the amount of hydrocodone in your body is down to 1 nanogram?

ok, so I wondered if anyone knows an easier way to find derivatives for Polynomial functions without using the instantaneous speed formula. I know, the formyla is no big deal... but this would save time...
Thanks,

Got some sherry glasses my wife particularly likes. This type are almost impossible to replace. Only got 3 left from the dozen that I bought from Pub stock. I have heard that tempering this poor quality of glass will increase thier strength. Is this true and if so what is the heating / cooling cycle and temperatures required?
