A man with a quadratically shaped head, with profile given by the function \(h(x)=4-3x^2\) where both \(x\) and \(h(x)\) are measured in decimetres, puts on a conical hat whose profile has a right angle at the tip. How much taller does he appear with the hat on if he wears the hat symmetrically? What are the coordinates of the point at which the hat touches his head.
