If the function Q is defined by the formula Q = 5w/(4h(z^2)), by what factor will Q be multiplied if w is quadrupled, h is doubled, and z is tripled?
Options
A) 1/9 B) 2/9 C) 4/9 D) 3/9 E) 2/27
We just need to find the factor thats all,   w -&gt; quadrupled -&gt; 4w   h-&gt; doubled -&gt; 2h   z-&gt; tripled -&gt; 3Z   Hence, Z^2 = 9Z^2   W is in numerator, and h*z in denominator.   Hence,   Additional factor being introduced = 4/2*9   =4/18 = 2/9 = 2/9
