Homework Monday, 4/16
Pre-Algebra: Pg. 342 - 343 #13 - 32, 40 - 45
Algebra: I gave you a worksheet in class. Recommended that you do at least 4 from the first section, 1 or both of the vertical motion, and at least 2 graphs. Here are the answers:
1. x = 6 or 3
2. x = 6 or -2
3. x = -4 or 3
4. x = -2.35 or -7.65
5. x = 2.5 or -4
6. x = -1/3 or 3
7. x = 1.42 or -8.42
8. x = 0.39 or -6.39
9. x = 0.41 or -7.41
10. x = 6
11a. 9.8175 m
11b. No.
11c. reaches at time t = 0.6 seconds, max height of h = 9.8 m
11d. after 2 seconds
12a. 71.55 m
12b. at 1.89 seconds and 7.31 seconds
12c. at 4.6 seconds, max height 102.8 m above the ground
12d. lands at 9.13 seconds
For 13 - 18, I will give the vertex first, and then the x-intercepts. You need to be able to also construct the actual graph.
13. Vertex: (-1, -4); Intercepts: x = -3, x = 1
14. V: (2.5, -9.25); I: x = 5.54 and x = -0.54
15. V: (0.75, -6.125); I: x = -1 and x = 2.5
16. V: (-0.5, 2.25); I: x = -2 and x = 1
17. V: (-2, 3); I: No x-intercepts.
18. V: (-4, -8); I: x = 1.66 and x = -9.66

Homework Friday, 4/13
Pre-Algebra: None. It would be great if you could have your 3 stocks figured out and "purchased" by Monday, though.
Algebra: Work on what you are weakest on for the test, which is Tuesday. Everyone should have something to do, so we can focus our review on Monday. Here are some recommended sections to take a look at.
Factoring: page 439 #17 - 40
Completing the Square: pages 239 - 240 #1 - 10 (basic); #21 - 30 (the "b" term is odd); #41 - 50 (the "a" term is not equal to 1)
Quadratic Formula: pages 245 - 246 #1 - 20 (basic); #31 - 34 (require some basic transformations first); #34 - 40 (require more complicated transformations first)
Vertical Motion: pages 252 - 257 #4, 6, 10, 17, 18
Graphing: You can practice graphing by setting any of the equations from the above sections equal to "y" instead of 0, and finding the intercepts, vertex, etc.
Also, page 635 #3; page 656 #1 - 10
