plese answer i and ii and all question 4

Hillsborough California Years Sunrise and Sunset time averages Month Sunrise Time (hrs) Sunset time (hrs) Daylight Hours Average Temp ['c) 7.3 17 3 10 13 5: 6.8 17 6 10 8 17 6.2 18.3 121 19 53 185 13.2 25 48 19 3 14 5 27 4.6 19.6 15 34 5 20 15 5.6 19.3 14 32 5.8 19 13 2 27 5.3 18.6 123 23 6.6 18.3 11.5 20 7.2 18 10.8 f(x) = 2.5 sin 2 7T (T - 3.5) +12.5 Use graphing calculator or technology to perform a sinusoidal regression that will determine the sine function that best fit the data of best fit equation. i. Write the equation in the form given, and then factor out the k value and rewrite the function so that the form matches that of your function from part a) ii. Graph the scatter plot with your curve of best fit and include this in your document. 4. For Temperature a) Use a graphing calculator or technology to perform sinusoidal regression that will determine the sine function that best fits the data. Record the equation. b) Choose a temperature (not a max or min temperature) and use the equation from part a) to find the months when the temperature is above your chosen temperature. c) Choose a month when the temperature is changing at a negative rate. Determine the instantaneous rate of change of temperature at that point
