Daylight function for 40° N Verify that the function D ( t ) = 2.8 sin ( 2 π 365 ( t − 81 ) ) + 12 has the following properties, where t is measured in days and D is the number of hours between sunrise and sunset. a. It has a period of 365 days. b. Its maximum and minimum values are 14.8 and 9.2, respectively, which occur approximately at t = 172 and t = 355, respectively (corresponding to the solstices). c. D (81) = 12 and D (264) ≈ 12 (corresponding to the equinoxes).

2. Suppose f(x) = 3x² - 5x. Show all your work for the problems below.
write it down for better understanding please
1. Suppose F(t) gives the temperature in degrees Fahrenheit t minutes after 1pm. With a
complete sentence, interpret the equation F(10) 68. (Remember this means explaining
the meaning of the equation without using any mathy vocabulary!) Include units. (3 points)
