URGENT HELP PLEASE the temperature of a room during an experiment can be modeled by the function f(x)=23.7 cos (Pi x /60) +18. Where f(x) is the temperature F degrees and x is the number is hours into the experiment. What is the lowest temperature the room reached during the expriement?
I got -5.7 F *
Answered by Damon
cos reaches -1
the range of cos or sin is from -1 to +1
so
-23.7 + 18 = -5.7 indeed
