Answers. 1. Answer : x varies jointly as y and z. x ∝ yz. x = kyz. 2. Answer : z varies jointly as x and the square root of y. z ∝ x √y. z = kx √y. 3. Answer : w varies jointly as x and y and inversely as z. w ∝ x y/z. w = kxy/z. 4. Answer : Since y varies jointly with x and z, y ∝ xz. y = kxz ----(1) Substitute y = 36, x = 4 and z ...
Joint and Combined Variation Practice Problems *Make sure to use correct UNITS, when applicable 1) If f varies jointly as g and the cube of h, and f = 200 when g = 5 and h = 4, find f when g = 3 and h = 6. 2) If y varies jointly as x and z, and y = 33 when x = 9 and z = 12, find y when x = 16 and z = 22.
What Is Joint Variation And Combined Variation? Joint variation is a variation where a quantity varies directly as the product of two or more other quantities. For example, the area of a rectangle varies whenever its length or its width varies.
Joint variation occurs when the ratio of one quantity to the product of the other two quantities is constant. Combined variation occurs when one quantity varies directly with one quantity and inversely with another.
25 wrz 2024 · Joint Variation refers to the scenario where the value of 1 variable depends on 2 or more and other variables that are held constant. For example, if C varies jointly as A and B, then C = ABX for which constant “X”.
If more than two variables are related directly or one variable changes with the change product of two or more variables it is called as joint variation. If X is in joint variation with Y and Z, it can be symbolically written as X α YZ. If Y is constant also then X is in direct variation with Z.
