OK, it is helpful if you post questions individually rather than all together like this. Also, Open Study is a tutoring site, not an answering service. It is helpful to us if you also explain why you don't understand the question, ask a concept question,  or if you post your solution (that is, answer and explanation) and ask us to check it for you.

Clear?
