Where did you get the idea that you could drop your whole homework assignment in here and then just walk off expecting someone to do your work for you? Not happening.

1. One question per post.

2. Show the work you have done so far.

3. Describe the difficulty you are having.

4. The more work you do first, the more help you are going to get. The limiting position on the other end is zero.
