HP Precalc Final Review

OK, my regular uploading site, fileden, isn't working, so this is a band-aid and hopefully I can come up with a better link tomorrow. I'd prefer a direct link, but this will have to do.

LImits Review Key

Click your mouse here for key.

Problem with #10 - should be 1/40.
Skip #14-16
Anything with absolute value or any piecewise defined functions can be analyzed with a calculator.

HP Precalc:
Test moved to Thursday.

Here are the worked out solutions for chapter 7. Remember, this is a pretty big file, so be patient and it may work better to right click and "save as."

Precalc Grades Updated

Sorry it took me so long on these. Tests aren't corrected yet, but I'll put those in as soon as I get them corrected. Now you or your parents can look on Schoolview to see how you're doing.

If you handed something in late, however, it may not be in yet because I put those in a special pile at school and didn't bring them home.

Also, GO WILD!!! Big OT winner last night!

Geometry Review (from Study Guide)

Here is a key to the study guide. I've also uploaded answers from the book part of the review here.

1a. 540 degrees
1b. 127 degrees
2. x=56
3. x=18
4. 157.5 degrees
5. 135 degrees
6. 225 degrees
7a. 101 degrees
7b. y=8, x=11
8. p=62, q=9
9. c=6, d=9
10a. 61 degrees
10b. g=8, h=20
11a. g=3.5, f=88
11b. x=2, y=9
12a. v=4, t=9
12b. (0.5, 1) !!!typo - should be D(-3,0)
13a. yes
13b. yes
14. (2)CPCTC, (3)opposite sides in a parallelogram are congruent
15. see #14
16. x=20
17. x=7
18a. Use distance formula
18b. Use slope formula
19. parallelogram, rhombus
20. x=27, y=4
21a. 60 degrees
21b. rectangle & square
22a. 56 degrees
22b. 112 degrees

23. (2)def of rectangle (3)angle RTA is congruent to angle CEA (4)angle RAT is congruent to angle EAC (4) AAS
24. Many different ways to show - AAS, SSS, SAS most common if you use the fact that diagonals bisect each other
25a. RT=15
25b. sometimes
26a. yes
26b. x=5.25
27a. yes
27b. Use CPCTC to show DA=EV, the it is by definition since bases are given parallel

30a. No
30b. trapezoid
30c. (3root13)/2
31a. Isosceles trapezoid
31b. rectangle
32a. no !!!Typo - forget that isosceles trapezoid stuff - look at the specific terms
32b. yes
33. angle B & angle A could be congruent, for example

HP Precalc - Chapter 5 Review Key

Here ya go. As awlays, find an error, get extra credit.

Looks like I didn't quite finish the last problem (sorry), but I got you far enough. You get the idea...

Also, a couple of you have requested the formulas powerpoint. While this isn't the focus of the test, you may want to look it over.
