Antonius is using some data to create a model for the average temperature in Riverside CA. On any given day of the year, d represents the number out of 365 days. For example, Jan 3 is when d=3. He has the lowest average temperature at d =43 at 36° F, and the next middle/moderate average temperature when d=223 at 68° F. help build an equation to model the cycle of temperature, assuming a period of 365 days for the year. Use your model equation to calculate the temperature on day 263. Round your answer to the nearest tenth.
