The number of hamburgers sold at a fast-food restaurant in Pasadena, California, is given by y = 10 + 5 sin x where y is the number of hamburgers sold and x represents the number of hours after the restaurant opened at 11 a.m. until 11 p.m., when the store closes. Find y' and determine the intervals where the number of burgers being sold is increasing.
