Rationalize the Denominator $$x = \sqrt { \frac { 2 W } { 85000 } }$$

Multiple Choice

Rationalize the denominator. Assume that all variables represent nonnegative numbers and that the denominator is not
zero.
-A simple exercise machine can be constructed by mounting a stiff spring securely to a wall and attaching a "T" handle to the free end of the spring. The arms can be exercised simply by pulling the "T" handle towards the
Torso. For a particular spring, the stretch distance is related to the work exerted by the equation x $$x = \sqrt { \frac { 2 W } { 85000 } }$$ where W is the work exerted in joules and x is the stretch distance in cm. How far will you stretch the spring if
You exert 669 joules of work? Round your answer to three decimal places.

A) 0.016 cm
B) 0.089 cm
C) 0.125 cm
D) 0.134 cm
