This is all I have. Some one please please pleeeeeaaaase check this over and see if I'm in any way on the right track. I haven't had much sleep the past few days and am really stressing over my courses. This is a take home part of our unit test. I hope I did this right because it could really save me from bombing the test. This is my attempt at a solution. All the formulas are there. I really need someone to tell me where I went wrong(if I did) and what to do to correct it. This is due at 10:50 tomorrow morning. I have 10 hours(some of that sleeping time). Thank you so very much to anyone who replies. I've never been this desperate.
