3. The number of hours of sunlight in a day of a leap year, in part of Ontario, can bemodelled by a sinusoidal function with a minimum of 8.9 on the 356th day of the year(December 21st), and a maximum of 15.4 on the 173rd day of the year (June 21st).a. Find a sinusoidal function that models this relationship.b. What days (on the calendar) are the closest to 14 hours in length?c. How long is the 218th day of a leap year?

The Transylvania hypothesis claims that the full moon has an effect on health-related behavior. A study investigating this effect found a significant relationship between the phase of the moon and the (x-4) + 100 where y is the number of consultations as a percentage of the daily mean and x is the days since the last full 15.12 number of general practice consultations nationwide, given by y = 1.9 cos moon. a. What is the period of this function? What is the significance of this period? The period is days. (Round to two decimal places as needed.) Choose the correct meaning of the period p in the context of the problem. The x-distance between the maximum and the minimum of the graph is p. Every p days there is a full moon. There were p% more consultations when there was a full moon. The average number of daily consultations is p. b. If there was a full moon on April 7, on what day in April does this formula predict the maximum number of consultations? What percent increase would be…
