Full Contact (Mental contact) Review (Modeled loosely on the game of Football) Rules: A coin toss (of course) determines who goes first. The coin-toss-winning team starts on the 20 yard line and tries to advance the football to a TD (so I guess it's really overtime football all the time). Advancing happens with a roll of the dice for yardage and the person chosen to answer the question (card drawn) must get it right. If the answer is "fumbled" the other team (person whose card is drawn) has an opportunity to recover. If the football advances, normal football rules (4 downs to make first in ten) apply. A touchdown will be followed by extra points as determined by team captain. One point is earned with one correct answer, two point with two correct answers. The decisions about unsportsmanlike conduct, delay of game, unnecessary geeking, etc. are made by the ref----no replay decisions. Surely you realize the real point is review for the test happening next time…..it's about 20% of your 9-weeks grade. This review won't be enough---study your previous quizzes and homework problems. Winning team starts the test with one extra credit point on test.

2
Give the decimal degree version of the angle 35˚42' 25". Round to nearest hundredth (Where do you go in Chicago in case of a tornado?) 2

3
(Soldier Field. They rarely get a touchdown there) 3 35.71˚

4
Use your calculator to find sec 123˚44'55" Round answer to 4 th decimal place (What is the name of the picture below?) 4

5
Answer is –1.8000 (football pi) 5

6
6 Albert's truck has wheels 36 inches in diameter. If the wheels are rotating at 630 rpm, find the truck's speed rounded to the nearest mph (Where do hungry football players play?)

7
7 Answer 67mph (In the Supper Bowl)

8
8 Give exact values for the following. Do not consult your calculator. (What do you call a lineman's kid?)

9
9 Answers: (Chip off the old blocker.....am I crackbacking you up?)

10
10 NO CALCULATOR! Find the cotangent of x if and if (What did the football coach say to the broken vending machine?)

11
11 answer: (Give me my quarterback!)

12
12 Use transformations to describe how the graph of the function below is related to the basic trigonometric graph y = sin x y= –2–3sin(x–π)

13
13 Compared to y=sinx vertical stretch of 3 vertical translation down 2 horizontal translation to right π reflected about x axis

14
14 State the amplitude, period, phase shift (horizontal shift), domain, and range for the sinusoid y = –2 cos (3x+1) Football Quote: "Nobody in football should be called a genius. A genius is a guy like Norman Einstein." Football commentator and former player Joe Theismann

15
15 Amplitude is 2 Period is 2π/3 Phase shift –1/3 Domain = all reals Range=[-2,2]

16
16 Give the domain and range of y=3sin(2x) Football quote: Steve Spurrier, Florida football coach, telling Gator fans that a fire at Auburn's football dorm had destroyed 20 books: "But the real tragedy was that 15 hadn't been colored yet."

17
17 Domain is all real numbers and range is [–3, 3]

18
18 NO CALCULATOR. Two of the functions below have identical graphs. Which two? (You must be able to explain how you got your answer)

19
19 A and B (one easy way to tell would be to check an easy point in all functions........let x=0 and see which have the same y value

20
20 Find exact value for the cosine of an angle so that tan = 2 and ("exact value" means decimal approximation won't work, which means your calculator is pretty much worthless)

21
Answer:

22
22 Find the length of the arc intercepted by a central angle of 2π/3 in a circle with radius 2 inches. Give both exact answer and also answer rounded to tenths.

23
23 Answer: 4π/3 or 4.2 inches

24
24 From the top of a 150-ft building, Polly observes Tony driving a car toward her. If the angle of depression to the car changes from 18˚ to 42˚ during the observation, how far does the car travel? (round to the nearest foot)

25
25 295 feet

26
Extra practice:page 439ff #1-68, 93-103 26
