The function f(t) = 20 sin (pi over 5t) + 12 models the temperature of a periodic chemical reaction where t represents time in hours. what are the maximum and minimum temperatures of the reaction, and how long does the entire cycle take? maximum: 20°; minimum: 8°; period: 12 hours maximum: 32°; minimum: −8°; period: 10 hours maximum: 20°; minimum: 12°; period: pi over 5 hours maximum: 32°; minimum: 8°; period: pi over 5 hours
