Question 196805
<font face="Garamond" size="+2">

If <i>y</i> varies directly as the square of <i>x</i>, then:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y = kx^2]


However, you need to solve for <i>k</i> to get a complete picture of the relationship.  And you haven't given enough information to be able to solve for <i>k</i>.  Your problem statement probably says <i>y</i> = 175 <u>when <i>x</i> </u> equals something.  Your next step would be to substitute 175 for <i>y</i> and whatever was given for <i>x</i>, then solve for <i>k</i>.  After that, you can set up the relationship with the calculated value of <i>k</i>, substitute <i>x</i> = 10 and determine the value of <i>y</i>.
