The average monthly temperature changes from month to month. suppose that, for a given city, we can model the average temperature in a month with the following function.
f(t)=49 - 26cos(π/6t)
in this equation, ft is the average temperature in a month in degrees fahrenheit, and t is the month of the year (january=1, february=2, find the following. if necessary, round to the nearest hundredth. find:
a. time for one full cycle of f: monthsb. minimum average temperature in a month : °fahrenheitc. number of cycles off per month:
