I have scanned my work and uploaded it as a single pdf file as an attachment below.

Complete the problems below. Note that:You must write your full work and solutions on scratch paper you will then upload (as with the homeworks and quizzes).  However, you do not need to rewrite the statements of problems, just make sure each problem number is correctly labelled.  You have 60 minutes to compete the exam. Blackboard will warn you once your 60 minutes is up.  You may then use bonus time.  This bonus time is to be used for scanning and uploading the exam only.  Continuing to work on the exam past the 60 minutes will results in a 10 point penalty per extra minute used.
