Question

The temperature of a chemical reaction ranges between −10 degrees Celsius and 50 degrees Celsius. The temperature is at its lowest point when t = 0, and the reaction completes 1 cycle during a 6-hour period. What is a cosine function that models this reaction?

Answer 1

f(t) = −30 cos pi over 3t + 20
f(t) = −60 cos pi over 3t + 30
f(t) = 30 cos 6t + 20
f(t) = 60 cos 6t + 30
