[Chapter 5]

Direct Variation1. Given P varies directly as the square of R, and P = 5 when R = 3. When P = 20, R = ?2. The relationship between variables c and d is given by C D3. If C = 7 when D = 2, find the value of C when D = 125Inverse Variation1. Given W varies inversely as the cube of V, and W = 6 when V = 2. When W = 76, V = ?2. The relationship between variables M and N is given by M 5. If M = 12 when N = 49, find

N

the value of N when M = 37Joint Variation1. Given G varies inversely as the triple of H but varies directly as double of I, and G = 2 when H = 4 and I = 6. When G = 5, H = 10, find the value of I?2. The relationship between variables S, R and T is given by S 9 R. If S = 14 when R = 49

Tand T = 3;find the value of R when S = 108 and T = 64 Cikgu Zaidi J-dai 2014, Hak Cipta Terpeliharapg. 1
