A city averages 14 hours of daylight in June (the longest days) and 10 in December (shortest days). Assume that the number of hours of daylight varies sinusoidal over a period of twelve months. Sketch the graph then find the Ampiitude, Vertical Shift, b value and Period. Write a sine equation to model the hours of daylight using the other information and a phase shift of pi/2
