The actual temperature inside an oven varies around the selected temperature. This variation can be modeled with a sine function. If the cook selected a temperature of 425 °F, then the actual temperature T in the oven is given by T = 20 sin(2x) + 425, where it is the number of hours since the oven first hit the selected temperature of 425°F. What is the highest actual temperature in the oven? 'F What is the lowest actual temperature in the oven? What is the period of this function? Give your answer in minutes. minutes When is the first time the oven will hit the highest temperature? Give your answer in minutes. minutes
