7. Given the following circle and undetermined angle measures of o and @ radians, answer the following questions. a. What is the value of o, the measure of the angle indicated in the figure? ( , y) 6.21 feet (6.7. 0) (0. 0) 6.7 feet b. Determine the values for x and y indicated in the figure. (-2.22, -6.32) c. What is the value of B, the measure of the angle indicated in the figure above? 8. Many industries follow seasonal employment patterns over the course of a year as holiday schedules and weather affect hiring. One example of such an industry is skiing facilities. The number of people employed at skiing facilities on average in the US between 2004 and 2014 can be modeled by N(m) = 33175 sin ( (m + 2) ) + 45825, where m is the month of the year with m = 1 representing January. a. Without solving, one can determine that there was never a month during which the average number of people employed in this industry was 12,000. Explain why this is true. b. What is the period of N? Interpret this value in the context of the situation. c. Determine the maximum average number of people employed in the US skiing industry. d. During what months will the answer to the previous problem occur? 9. For the function f (0) = -0.4 sin 1.5 (8 - ) ) - 1, a. Describe the transformations made to sin(0) to create f
