The average daily high temperature in Madrid peaks at 92°F in the summer and drops as low as 33°F in the winter. The temperature
can be modeled by T (d) = 29.5 cosine (StartFraction 2 pi Over 365 EndFraction (d minus 204) ) + 62.5, where d represents the day number of the year (January 1 is 1, January 2 is 2, and so on). How many days during the year is the high temperature expected to be 75°F or above?

Answer:
C) 131
Step-by-step explanation:
It wants us to find how many days out of the year that the temperature goes above 75 degrees Fahrenheit.
To do this, I set the y value equal to 75 (it should be , but I thought it'd be easier to see this way).
From there, you can easily visualize the days that were above and 75 degrees.
It's just simple subtraction from here:
269-138=131
