Math Box: Square-Root Relationships Learning Goal: To understand and use square-root relationships. Two quantities x and y are said to have a square- root relationship if y is proportional to the square root of x. We write the mathematical relationship as where A is a constant. SCALING If x has the initial value €1, initial value y₁. Changing from ₁ to x2, changes y from y₁ to y₂. The ratio of y₂ to y₁ is ● Y2 Y1 ● y=A√x, = A√ √2 A√T = x2 which is the square root of the ratio of x2 x1 Generally we can say that then y has the to x1. If you increase x by a factor of 4, you increase y by factor of √4 = 2. If you increase x by a factor of 9, you increase y by factor of √9 = 3.
