14. The inside temperature of a building is modelled by T(t) = 3cos(15t) + 22, where T' is the temperature in °C and t is the number of hours elapsed since 5 A.M. The graph is shown below. a) Using an appropriate calculation, explain why the coefficient of t in the equation is 15. T(C 30 28- 26 -24- 22 -20 18+ 16 14+ -12- 10 8+ 6 4+ -2+ 5 am 5pm 5am b) In another building, the temperature fluctuates in a similar manner except that the maximum temperature is 31°C and the minimum temperature is 19°C. Determine the defining equation that models the temperature in this other building.
