Happy Monday! We spent today in class getting more ready for tomorrow's chapter 13 test. We went over the review sheet from Friday and answered any questions that students had. We then went over a few sample test questions together before getting started on the 2nd review sheet. The answers to the review sheet are posted below.
Assignment: Chapter 13 Review #2
1. pt on graph
2. pt. on graph
3. pt. on graph
4. pt. on graph
5. quadrant III
6. x - axis
7. 5 radical 2
8. (x + 2)2 + y2 = 49
9. undefined
10. (-5, -12)
11. 13
12. show that AB is congruent to CD; both have length = 7
show that AB is parallel to CD; both have undefined slope
13. 3 radical 5
14. (-3/2 , 1)
15. (-6, -8)
16. 2
17. a. (-4, -1); b. 10
18. (x-1)2 + (y - 5)2 = 1
19. (a + 1, b)
20. a. 3/5 b. -5/3
21. (4, 17)
22. y = -5/8 x - 39/4
23. y = 4x - 3
24. y = -5x + 2
25. ( 1, 3)
26. a. (b, radical a squared - b squared)
b. (a + b, radical a squared - b squared)
27. Draw triangle with points (0, 0), (2a, 0) on x-axis; (2b, 2c)
Midpoints of sides are (b,c) and (a + b, c)
b. prove that the distance between the two midpoints is = a;
distance of base of triangle on x-axis = 2a
midsegment = 1/2 length of base
