Please note that we don't do students' homework for them. Our tutors try to give you the information to help you complete your assignment on your own. If there's not a tutor with this specialty online right now, be sure to go back into your textbook or use a good search engine. ( http://www.sou.edu/library/searchtools/ )
Once YOU have come up with attempted answers to YOUR questions, please re-post, and let us know what you think. Then someone here will be happy to critique your work.
