Answer:
a = 
Step-by-step explanation:
Given
G = 4ca - 3ba ← factor out a from each term on the right side
G = a(4c - 3b) ← divide both sides by (4c - 3b)
a = 
Answer: B.
Step-by-step explanation:
I wrote my answer in the comments, but I’ll say it again; the answer is likely B. Because the other options are not very relevant. B. Is the option most likely to be disputed on. I do not know if this is the answer however, but this was what I thought.

Given:
Amplitude = 2
Midline = 5
Period of
.
To find:
The cosine function.
Solution:
The general cosine function is:
...(i)
Where, |A| is amplitude,
is period,
is phase shift and D is the mid line.
Period of function is
. So,



Substituting
in (i), we get


Therefore, the required cosine function is
.
