The model for long-term average temperature f (x), in degrees Celsius, at the Willburn airport is represented by the equation f of x is equal to 5 times sine of the quantity x over 12 end quantity plus 14 and 5 tenths period If x represents the month of the year, in which months will the temperature be 19.5C? (5 points) x = 3 + 24n and x = 15 + 24n x = 3 + 2n and x = 15 + 2n x equals pi over 4 plus 24 times pi times n and x equals 5 times pi over 4 plus 24 times pi times n x equals pi over 4 plus 2 times pi times n and x equals 5 times pi over 4 plus 2 times pi times n
