Question

The average daily maximum temperature for Shane’s hometown can be modeled by the function f(x)=12.2cos(πx6)+54.9 , where f(x) is the temperature in °F and x is the month. x = 0 corresponds to January. What is the average daily maximum temperature in March?

Answer 1

I just took the quiz, and its 61 degrees! Good luck!

Answer 2

For this case we have the following:
x = 0 (January)
x = 1 (February)
x = 2 (March)
Evaluating x = 2:
f (x) = 12.2 * cos (π * x ^ 6) +54.9
f (2) = 12.2 * cos (π * (2) ^ 6) +54.9
f (2) = 67.1
Answer:
the average daily maximum temperature in March is 67.1 ° F
