a) W varies directly with x.
W=k%2Ax .... where k is a constant
b) avaries inversely with the square of b.
a=k%2Fsqrt%28b%29 .... where k is a constant
c)
Z varies jointly with x and+y.
Z=k%2Ax%2Ay .... where k is a constant
d)
P varies directly with the square root of f+and inversely with g.
P=k%28sqrt%28f%29%2Fg%29 .... where k is a constant
