MATH 150 HW: CHAPTER 7 SPRING 2009 Write your name and class and clearly separate sections! See the syllabus. You should photocopy your homework for future reference. Show work where appropriate, and use “good form and procedure,” as in class! This is due at the Final, though you should finish it before our last quiz. Graded out of 15 points. “*” denotes “See Hint below.” Read some of the book’s Examples for additional assistance. START DESIGNING YOUR SHEET OF NOTES FOR THE FINAL! 7.1: Skip. 7.2: 1-21 odd, 25, 27, 31-35 all, 39-47 odd*, 56* Note on 39, 41, 43: The back of the book gives simplified answers. Try to get them!
