The correct option A: y = -4 cos Ф/4, is the cosine function for the graph.
<h3>Define the term cosine function?</h3>
The ratio between the angle's adjacent leg and the hypotenuse when it is regarded as a leg of a right triangle is a trigonometric function for an acute angle.
- One of the three fundamental trigonometric functions, cosine is the complement of sine (co+sine) and one of the three main trigonometric functions.
- Y=cos(x) has its greatest value when x = 2nπ, wherein n is an integer.
- Y=cos(x) has a lowest value for x= π+2nπ , wherein n is an integer.
For the given graph,
cosine function: y = -4 cos Ф/4.
In which, -4 is the amplitude (maximum displacement from the x axis).
Negative sign shows, the displacement is taken along negative y-axis.
And, Ф/4 is the phase angle.
Thus, the cosine function for the graph is y = -4 cos Ф/4.

Answer:
$11.54
Step-by-step explanation:
The computation of the greater amount on card V than card U by considering the minimum payment is shown below:
But before that first we have to compute it separately and then take a difference to reach a solution
On Credit card U
= Balance × given percentage
= $414.55 × 2.82%
= $11.69
On Credit card V
= Balance × given percentage
= $751.81 × 3.09%
= $23.23
So, the difference in amount is
= $23.23 - $11.69
= $11.54
