Day 7 (06-26-2008)    TEST DAY -- In section 4.1 do problems #47, 49, 55, 57.  (Hint: the growth factor for problem 47 is 24/20 = 1.2 and the decay factor for 49 is 96/120 = 0.8  For problems 55 and 57 you first need to calculate the growth factor using the points on the graphs).  Get caught up with the rest of the chapter 4 homework over the weekend.

Day 6 (06-25-2008)    Study for TEST 1 tomorrow.  In section 4.1 do problems #1, 3, 7, 11 (find the percent increase in bees per week), 15, 33, 37, 41, 61, 69.  Your first priority will be to study for the test.  When you study, make sure you can do the assigned chapter one HW problems independently without any help.

Day 5 (06-24-2008)    In section 1.5 do problems #11, 17, 21, 27, 33, 45, 47.  Read the light colored box on page 80. for clues on how to do #11 and 33.  In section 4.1 do problem #11, 12.

Day 3 (06-19-2008)    In section 1.2 do problems #17, 18, 27, 31 (parts a and c only), 45, 59, 68.  In section 1.3 do problems 1, 9, 19 (parts a, b, and c only), 41 (Read the directions for 41 carefully.  You will need to use the TRACE button and the LEFT and RIGHT arrow keys on your graphing calculator). 

Day 2 (06-18-2008)    In section 1.1 do problems #11, 19, 35.  For #35, find the actual equation of the line in slope/intercept form.  In section 1.4 do problems 1, 11, 17 (parts ii. only), 21, 23, 24, 29, 33.  

Day 1 (06-17-2008)    Familiarize yourself with the class website and syllabus.  Read the 4-step procedure as found on page 11.  In section 1.1 do problems 13, 17, 33, 35 (for #33 and 35 just find the two intercepts; don't worry about the equation)
