Question

The function f(t) = 65 sin (pi over 5t) + 35 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: 65°; minimum: 35°; period: pi over 5 hours

Maximum: 100°; minimum: −30°; period: pi over 5 hours

Maximum: 65°; minimum: 35°; period: 10 hours

Maximum: 100°; minimum: −30°; period: 10 hours
