The correct option is (b) h=0.5cos(/6t)+9.5.
The equations can be used to model the height as a function of time, t, in hours is h=0.5cos(/6t)+9.5.
The following is a presentation of the cosine function's generic form;
y = a + cos(bx - c) + d
amplitude = a
b = cycle speed
Calculation for the model height;
The height, h (feet) of the tip of the hour hand of a wall clock varies from 9 feet to 10 feet.
Obtain amplitude 'a' as
The time 'T' is calculated as-
Now, calculate 'd'
Therefore, with the height as a function of time, t, expressed in hours, can be modeled by the following equations:
h=0.5cos(/6t)+9.5
