The temperature in Edmonton, over the course of a year, can be approximated using the sinusoidal function t(x) = 16.11sin(0.51x-1.75)+9.14 where T represents the temperature in C and x represents the number of the month, where January 1st is month number 1, February 1st is month number 2, etc. What would the temperature in Edmonton be on August 1st?

Chapter 8 Sinusoidal Functions 1. The temperature in Edmonton, over the course of a year, can be approximated using the sinusoidal function t(x) = 16.11sin(0.51x-1.75)+9.14 where T represents the temperature in C and x represents the number of the month, where January 1st is month number 1, February 1st is month number 2, etc. What would the temperature in Edmonton be on August 1st? 2. A sinusoidal graph has an amplitude of 10 and a maximum at the point (18, 5). Determine the midline of the graph
