In a given region, the number of daylight hours varies, depending on the time of year. This variation can be approximated with the sinusoidal function: H = 5 sin 2 1 365 (d - 95) +13 H is the number of hours and d represents the day number of the year. (using January 1 as day 1, January 2 as day 2, . . . and so on) a) Determine the number of daylight hours (rounded to the nearest whole number) that occurs on February 26 (day 57). (1 mark) a) Find the two (2) day numbers of the year (whole numbers) when the approximate number of daylight hours is 16 hours. (2 marks)
