Answer:
The temperature at 9AM = 75°F
Step-by-step explanation:
Consider D(t) be the temperature in Fahrenheit at time t, where t is measured in hours since midnight. It knows when the maximum temperature occurs. Then it can create a model using a cosine curve.
Vertical shift, D = 85°F
Amplitude, A = (105-85)°F = 20°F
Horizontal stretch factor, B = 2π/24 = π/12
Horizontal shift = -(12+5) = -17
Using the information, we have this model
D(t) = 20cos [π/12(t-17)] + 85
D(9) = 20cos [π/12(9-17)] + 85
= 20cos [-2π/3] + 85
= -20 x 1/2 + 85
= 75°

It is helpful because when you divide numbers that keep on repeating you have to round it to some point and the tenths or hundreths makes it easier to write and for other people to see. Also, you can't write repeating decimals forever you have to stop at some point so rounding to the hundreths helps.
