If the function Q is defined by the formula Q = 5w/(4x(z^2)), by what factor will Q be multiplied if w is quadrupled, x is doubled, and z is tripled?
We just need to find the factor thats all,
w -> quadrupled -> 4w
x-> doubled -> 2x
z-> tripled -> 3Z
Hence, Z^2 = 9Z^2
W is in numerator, and x*z in denominator.
Additional factor being introduced = 4/2*9
=4/18 = 2/9 = B
