The cosine function with the given characteristics is:
f(x) = 3*cos(x/2 - pi).
<h3>
How to get the cosine function?</h3>
The general cosine function is:
f(x) = A*cos(kx + p)
Where A is the amplitude and p is the phase, then we know that:
A = 3
p = -pi
Then we have:
f(x) = 3*cos(kx - pi)
And the period is equal to 4pi, then we must have that:
k*(x + 4pi) - pi = k*x - pi + 2pi
k = 1/2
Then the function is:
f(x) = 3*cos(x/2 - pi).

Answer:
Table D.
Step-by-step explanation:
According to the laws of a function, one input can not have multiple outputs.
3 - 1
3 - 4
2 - 3
Three has more than one output; 1 and 4.
2 - 7
5 - 6
2 - 9
Two has more than one output; 7 and 9.
1 - 5
7 - 2
7 - 3
Seven has more than one output; 2 and 3.
3 - 4
1 - 5
8 - 5
While i'm not sure what the function is, it has no repeating input-outputs (only outputs). I may not be 100% correct, as i'm taking the test right now in fact, but I certainly hope this is the right answer (for the both of us!) I'll edit my answer if it's indeed incorrect.
Answer:
66$
Step-by-step explanation:
50$-11$+27$
66$
She ordered 128 CD's because 11*8 is 88 and 5*8 is 40 and you add them both together.
I think it is 33% because 20/60 as a decimal is .33 and as percent would be 33%
