If y is directly proportional to the square root of x, write down the equation connecting x, y and a constant k.   =

If y2 is inversely proportional to x, write down the equation connecting x, y and a constant k. y2  =

x is directly proportional to yWhen x is equal to 12, y is equal to 360When y=kx, what is the value of k?I DON'T KNOWSUBMIT ANSWER

Given that y is directly proportional to x√3 such that y=kx√3, where k is a constant, and y = 6 when x = 8, find(a) the value of k,(b) the value of x when y = 15.

If one of the roots of the quadratic question x2−x=k𝑥2-𝑥=𝑘 be square of the other, then k=
