During his weather report after the last snowstorm, a Baltimore meteorologist reported the low temperature was 26°F at 6 a. m. The high temperature was 44°F, and occurred at 6 p. m. The temperature in Baltimore on this day can be modeled by the sinusoidal function T=a⋅sin(π12x)+d

where T represents the temperature in degrees Fahrenheit x hours after midnight.

Part A:

Determine the values for the amplitude and midline.
