You were supposed to have read the guidelines when you registered for the forum! Thus, you should know that no one is going to do your homework for. That wouldn't help you or us. Try the problem your self so we will know what kind of help you need. (As far as I can see, there is no way to simply "write down" the information in the blanks. You will need to set up two equations and then solve the equations simultaneously to find the information you need.)
