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

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

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

Answer is –1.8000 (football pi) 5

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 Answer 67mph (In the Supper Bowl)

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

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

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

11 answer: (Give me my quarterback!)

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

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

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

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 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 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)

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 Answer: 4π/3 or 4.2 inches

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)

25 295 feet

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