QUESTION 1 For what values is the statement cos 1 (cos (8)) = @ true? Explain your answer. QUESTION 2 Porter is sitting in a bucket of a Ferris wheel with a 53-foot radius at the 3 o'clock position. The Ferris wheel begins to move counter clockwise. a) What is the angle of rotation when Porter is 35 feet above the Ferris wheel's center? b) What is the angle of rotation when Porter is 12 feet to the left of the Ferris wheel's center? QUESTION 3 A shoreline observation post is located on a cliff such that the observer is 354 feet above sea level. When initially spotted, the angle of depression (the angle at which an observer needs to look down) from the observation post to an approaching ship was 5.9. a) Draw a diagram of the situation and label each known and unknown quantity measure. b) How far out to sea was the ship when it was first spotted? c) After watching the ship for 34 seconds, the angel of depression was 61.7. Assuming the ship was moving at a constant rate, estimate the ship's velocity. d) If the ship were to continue on its course at the same velocity, how much time from the second reading will elapse before the ship crashes into the shore?
