what is ...
(1/2)^3 * (2)^4
If x is jointly proportional to the cube of y and the fourth power of z. In what ratio is x increased or decreased when y is halved and z is doubled?
4 answers
x1=ky¹ z⁴ x2 = k(y/2)³ (2z)⁴
Xx= 2k y³z⁴
x²=2y³z⁴ = 2 x²:x¹=2:1
x¹ y³z⁴ 1
ans:2:1
Xx= 2k y³z⁴
x²=2y³z⁴ = 2 x²:x¹=2:1
x¹ y³z⁴ 1
ans:2:1
V varies directly as E.if j=4 then E=225
x is jointly proportional to the cube of y and inversely to the square of z
