Jamal is studying the temperature changes in water as he moves it from the freezer to a bunsen burner. he finds that the temperature changes happen to behave in a sinusoidal manner. so, he develops a model to determine when the temperature will be at a peak and when it will be at a valley. he finds that at t = 4 minutes, the temperature reaches a maximum of 26° above freezing, and at t = 30 minutes, the temperature reaches a minimum of 10° below freezing. which equation best models this situation? a) y = 18cos(1/26(x - 4)) + 8 b) y = 8cos(1/26< (x - 4)) + 18 c) y = 18cos(pi/26(x - 4)) + 8 d) y = 8cos(pi/26(x - 4)) + 18
