The answer is 23 units
I wrote a solution, if you don't understand anything, just ask:)
The maximum value is actually the maximum of y
So, you don't need to care about the stuff inside cosine function,
Cosine function is always within the range of [-1,1]
So here, ymax = -1 + 6* 1 = 5
Correct me if I'm wrong, but isn't it 1?
((1/5)/6)x6=1/5
I think it 3/18 if it’s lowest terms/simplest form 1/6
Any value of x makes the equation true.
