The equation can be used to model the height as a function is where t is time, the second option is correct.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know the general equation for the cosine function:
Where A is the amplitude
We have a wall clock that varies from 9 feet to 10 feet.
The value of 'A' is given by:
b is the cycle speed, we know:
(T is period)
The value of d is given by:
d = 9.5
The equation can be modeled:
(c =0 and y =h)
Thus, the equation is
