Hello Need help with this question and it has 3 parts.
2. In an Australian city, the time of the sunrise can be found using the trigonometric function S = 4.6 sin 182 (- (d – 6)) + 5 where S is the number of hours past midnight and d is the number of days into the year. a) Graph the function on a calculator or online program from d = 0 to d = 365. Sketch your graph here. Page 23 of 33 WCLN PCMath 12 - Rev. 2019 b) Use your graph to find the time to the nearest minute when the sun will rise on the 27th day of the year. c) Use your graph to determine how many days in the year that the sunrise is after 8 am.
