Final answer:
The temperature change from day to night is found by subtracting the night temperature from the day temperature. With a day temperature of 36.6℉ and a night temperature of -12.6℉, the change is 49.2℉.
Step-by-step explanation:
The temperature change from day to night is calculated by subtracting the night temperature from the day temperature. The day temperature is 36.6℉ and the night temperature is -12.6℉. The formula for the temperature change (T_change) is T_change = T_day - T_night.
T_change = 36.6℉ - (-12.6℉)
T_change = 36.6℉ + 12.6℉
T_change = 49.2℉
So, the correct answer is D) 49.2°F.
