Joint or Combined VariationVideos, worksheets, games and acivities to help Algebra students learn about joint or combined variation.
Joint VariationJoint Variation
Joint Variation Application The energy that an item possesses due to its motion is called kinetic energy. The kinetic energy of an object (which is measured in joules) varies jointly with the mass of the object and the square of its velocity. If the kinetic energy of a 3 kg ball traveling 12 m/s is 216 Joules, how is the mass of a ball that generates 250 Joules of energy when traveling at 10 m/s? Direct, Inverse and Joint Variation
Combined VariationIn Algebra, sometimes we have functions that vary in more than one element. When this happens, we say that the functions have joint variation or combined variation. Joint variation is direct variation to more than one variable (for example, d = (r)(t)). With combined variation, we have both direct variation and indirect variation.How to set up and solve combined variation problems.
How to solve problems involving joint and combined variation y varies jointly as x and z and inversely as w, and y = 3/2, when x = 2, z =3 and w = 4. Find the equation of variation.
