Outside temperatures over the course of a day can be modeled as a sinusoidal function. Suppose the temperature varies between 46°F and 62°F during the day and the average daily temperature first occurs at 10 a. m. How many hours after midnight does the temperature first reach 50°F?

The maximum distance (in nautical miles) that a radio transmitter signal can be sent is represented by the expression 1.23h√, where h is the height (in feet) above the transmitter. estimate the maximum distance x (in nautical miles) between the plane that is receiving the signal and the transmitter. round your answer to the nearest tenth.
