Find an equation for the surface consisting of all points p for which the distance from p to the x-axis is 5 times the distance
guajiro [1.7K]
Distance from P to the x-axis = 2x distance from P to the yz-plane 

<span>Distance to the x-axis of a point P=(x,y,z) is (y^2+z^2)^1/2 </span>
<span>Distance to the yz-plane of a point P=(x,y,z) is x </span>

<span>So your equation is: </span>
<span>(y^2+z^2)^1/2 = 2x </span>
<span>=> y^2 + z^2 = 4x^2 </span>
<span>=> y^2 + z^2 - 4x^2 = 0
