An airplane is asked to stay within a holding pattern near an airport. The function d(x) = 80 sin (0.93x) + 170 represents the distance d, in miles, that the airplane is from the airport at time x, in minutes (a) When the plane enters the holding pattern, x = 0, how far is it from the airport? It is 170 miles from the airport. (b) During the first 14 minutes after the plane enters the holding pattern, at what time x is the plane exactly 130 miles from the airport? The solution set is } (Round the final answer to two decimal places as needed. Round all intermediate values to three decimal places as needed. Use a comma to separate answers as needed.)
