Joint Variation . 1. P varies jointly with Q and R. When P = 98, Q = 2 and R = 7. Find an equation connecting P, Q and R. hence find P when Q = 15 and R = 8. 2. A varies as the square of B and inversely as C. When A is 6, B is 5 and C = 100. Calculate A when B is 12 and C = 72. 3. H varies directly as the square of L and inversely as the square ...

Directions: State whether each equation represents a direct, inverse, or joint variation. State the constant of variation.

Joint y =kxmzn There are more than two quantities related; may also be combined with indirect variation. z varies jointly as x and the square of y and inversely as w. If z =25 when x =10, y =2,and w=8, determine an equation and find the value of z when x =12, y =2.5,and w=10. Example 1

Practice: Direct, Inverse, and Joint Variation . Name: _____ Directions: State whether each equation represents a direct, inverse, or joint variation. State the constant of variation. 1. yx =2 x 2. 5 =y
