The temperature of a chemical reaction ranges between 20 degrees celsius and 160 degrees celsius. the temperature is at its lowest point when t = 0, and the reaction completes 1 cycle during an 8-hour period. what is a cosine function that models this reaction?
answer choices
f(t) = -90 cos pi/4t +70
f(t) = -70 cos pi/4t +90
f(t) = 70 cos 8t +90
f(t)= 90 cos 8t +70
