It is the third option on Edge
Let's analyse the function

The amplitude is A, so we want A=1.5
Now, we start at x=0, and we have 
After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be 
So, we have

so, the function is

Answer:
y = 2w / x^2.
Step-by-step explanation:
w = 1/2x^2 y
We divide both sides by 1/2 x^2
y = w / (1/2 x^2)
y = 2w / x^2.
Answer:
y = 2x - 5
Step-by-step explanation:
8x - 4y = 20
The slope intercept form is
-4y = -8x + 20
y = 2x - 5
