Answer 2

first off , ignore the stupid \(\frac{\pi x}{30}\) it has nothing to do with your answer
what is the very largest cosine can be ?

Answer 3

How would i find that? @satellite73

Answer 4

just know it

Answer 5

7.5?

Answer 6

hold on, i didn't ask that

Answer 7

just what is the largest possible value that cosine can take, not the largest possible value that whole thing can take,
but you are right, the largest possible value of \[-7.5\cos(\text{whatever})\] is \[7.5\]

Answer 8

then to get your answer, add \[7.5+31.4\] and you are done

Answer 9

I have another question @satellite73 just tell me if its right

Answer 10
