Answer 1

You have posted several questions all at once. I answered the first one, but these others have a lot of parts to them. Did you even try to answer any of these questions? We are certainly here to offer help, but we frown on doing homework. It is against Wyzant's policies. Please try to answer as much as you can, and then post the parts that you don't understand. We will then help.
