Joint Variation · If x men take y days to plough z acres of land, then x varies directly as z and inversely as y. · The equation for the given problem of joint ...
Direct variation between variables x and y can be expressed as: y = kx, where 'k' is the constant of variation and k ≠ 0 y = kxz represents joint variation. Here, y varies jointly as x and z. More Examples on Joint Variation. y = 7xz, here y varies jointly as x and z y = 7x 2 z 3, here y varies jointly as x 2 and z 3 Area of a triangle = is ...
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 ...

Joint Variation, where at least two variables are related directly. For example, the area of a triangle is jointly related to both its height and base.
Mar 12, 2021 · Joint Variation – Introduction. 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”. The joint variation will be useful to represent interactions of multiple variables at one time.
Example 4: Translating Words Into Mathematical Statements The kinetic energy E of a moving object varies jointly as the mass m of the object and the square of the velocity v. The acceleration A of a moving object varies directly as the distance d it travels and varies inversely as the square of... ...
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. We say that A ∝ lw, where A is the area, l is the length and w is the width.
Joint variation describes a situation where one variable depends on two (or more) other variables, and varies directly as each of them when the others are held constant. We say z varies jointly as x and y if. z = k x y. for some constant k. Example: If z is jointly proportional to x and y and z = 6, when x = 3 and y = 4, find z when x = 7 and y ...
Example: If z is jointly proportional to x and y and z = 6, when x = 3 and y = 4, find z when x = 7 and y = 4. Find k: 6 = 3 ( 4) k. k = 1 2. Then, find z when x = 7 and y = 2. z = 1 2 ( 7) ( 2) z = 7.
