The average daily minimum temperature for Pablo’s hometown can be modeled by the function f(x)=15.3sin(πx6)+44.1 , where f(x) is the temperature in °F and x is the month.

x = 0 corresponds to January.

What is the average daily minimum temperature in June? 

Round to the nearest tenth of a degree if needed.

Use 3.14 for π .

 

The temperature of a room during an experiment can be modeled by the function  f(x)=23.7cos(πx60)+18 , wheref(x) is the temperature °F and x is the number of hours into the experiment.

What is the lowest temperature the room reached during the experiment?

Round to the nearest tenth of a degree if needed.

Use 3.14 for π .

If January is 0 , then June would be x= 5      put 5 in as the value of x to get

F degrees = 43.4 degrees   (using RADIANS)

 

Room temp problem will need how many hours the experiment is running.
