Please don't post more than two questions in a thread. Otherwise the thread can get convoluted and difficult to follow. Start new threads as necessary for remaining questions. eg. If you have five questions, post two of them in two threads and start a new thread for the remaining one etc.
And if the question has more than two parts to it, it is best to post only that question and its parts in the thread and start a new thread for other questions.
Also, this looks like it's an assignment that counts towards your final grade. MHF policy is to not knowingly help with such questions.
