Need help with these practice questions for my test.... please explain in detail. I know the image is poorly taken so if you need clarification let me know. Thanks!

tations: emonstrate an understanding of the meaning and a fake connections between trig ratios and graphical functions and between trig functions (#4-7, 9). Demonstrate an understanding of averag instar s of change (#8) Briefly explain how radians and degrees are related. You may use a diagram and/of example(s) to support your answer. 2. An arc 12 cm long subtends a central angle of a circle with a radius of 15 cm. Determine the measure of the central angle in radians. 3. Represent the following in radian measure in terms of it and then evaluate to one decimal place. Show calculations. a. 450 b. -30 4. Convert to degrees. Show calculations. 4TT a. 3 b. 3 5. For each trigonometric ratio below, use a sketch to determine which quadrant the terminal arm lies in. State the exact value of the trigonometric ratio. 4TT 5 TC a. sin 3 b. cot c. cos 2 6. The function y=cosx is reflected in the x-axis, vertically stretched by a factor of 6, horizontally compressed by a factor of 1/5, horizontally translated n/3 units to the left and vertically translated 10 units up. Write the equation of the new function. ** You not need to explain. 7. Sketch the graph of each function. X b. y = csc(2x) a. y = -2sin 2 6 ) - 3
