Question

Best answer will be given

Write the quadratic variation equation for the relationship:

y varies directly with x^2 and y = 36 when x = 3.

Answer 1

Since y varies directly with x^2,
the equation is y = kx^2 (k is the constant)

Since y=36 when x=3, substituting these values gives
36 = k(9)
k=4

So the quadratic variation equation is
y=4x^2
