Please do not repost questions that have been recently asked.  It pushes others down and off the page.  If you need immediate help, there are several paid tutors on the site.  Here's a hint: When you repost the same questions, or a string of questions that appears to be from the same assignment, you tend to get skipped.  If you need help with more than a few questions, a tutor is your best bet.
