College Algebra - We began taking our quiz over Sec. 5.6 - 5.8. No HW for Tuesday.

Accl. Geometry - We worked on the partner portion of our final exam.

*Note: We will complete the Ch. 5 quiz on Tuesday and then begin the group portion of the final exam in class. Students will have at least the second half of class on Tuesday and all of the class period on Wednesday to complete the group portion of the final. Students will work in groups of 3 and will be able to use their text and all of their notes on this portions, which will account for 20% of the final exam grade.**Note: Each student will complete an individual portion of the final exam during the assigned exam period on Friday. Students should bring their calculator and may bring a one-page handwritten sheet of notes (8.5 x 11 piece of paper). This portion of the final will account for 80% of the final exam grade.*Accl.

### Tuesday, December 9

College Algebra - We discussed Sec. 5.7 - the ambiguous case of SSA. HW for Wednesday - Complete pg. 324 #11 - 16 all and #20 - 28 even.

Accl. Geometry - We worked through Sec. 7.2 -properties of isometries. HW for Wednesday - Read Sec. 7.2 and complete pgs 380 - 382 #1 - 12 and #15 - 18.

HW answers from Monday - pgs 372 - 375

1) Rigid; reflected but the size and shape do not change

2) Nonrigid; the shape achanges

3) Nonrigid; the shape stays the same but the size changes

4) Reflect --> "flip" the figure over the given line

If the given line is the y-axis, then every point (x, y) maps onto the point (-x, y)

5) Rotate --> "spin" the figure around the given point

If the given point is the origin, then every point (x, y) maps onto the point (-x, -y).

6) Translate --> "slide" the figure in the direction of the given arrow

If the given vector is horizontal and has a length of 3 units, then every point (x, y) maps onto the point (x+3, y).

7) exapmle - a boat moving acorss a lake

8) example - a ferris wheel

9a) example - fold the paer so the the two images match up; crease the paper along this fold; the crease is the reflection line

9b) example - creat a segment that connects two corresponding points (one from each figure) and the construct the perpendicular bisector of this segment

10a) example - extend the three horizontal segments onto the other side of the reflection line, measure the distance form the reflection line to various critical points in the orignal figure and then locate the images of these points on the horizontal lines on the other side of the reflection line

10b) shaded square is now in the lower right, the shaded circle is now in the lower left, and the shaded triangle is located to the right of the center line

11) the circle should face due left, the pie shape should face the upper right, and the equal sign should face the lower right

12) 1 reflection

13) 4 reflections and 4 rotations

14) 1 reflection

19) P(-a, b); Q(-a, -b); R(a, -b)

16), 17), 18), and 20 - We will discuss the other problems in class tomorrow.

pg 289-290

1) - 3) - we will discuss in class tomorrow

4) y = -x + 2

5) y = -(6/13)x + (74/13)

6) y = x + 1

7) y = -3x + 5

8) y = (2/5)x - (8/5)

9) y = 80 + 4x

10) y = -3x + 26

11) y = -(1/4)x - 3

12) y = (6/5)x

13) y = x + 1

14) y = -(2/9)x + (43/9)

Pg 348

1) (-0.5, 3)

2) (-3, -3)

3) (0.4, 3)

4) (7, -2)

5) infinite solutions

6) no solution

9a) Plan A: y = 4x + 20 and Plan B: y = 7x; x = 6 hr 40 min and y = $46.67

9b) The point of intersection shows where the two plans have the same cost

9c) Plan B; $50 will get you 75 hours with Plan A
