1. Determine the equation of the line that is tangent to the ellipse \(E\) at the point \((8,12)\), where \(E\) is the ellipse that is given by the equation \[\frac{(x+2)^2}{25}+\frac{(y-4)^2}{16}=8.\]
2. The line tangent to a quadratic polynomial \(f\) at \((2,5)\) is given by \[L(x)=7(x-2)+5.\] Determine the line tangent to \(f^{-1}\) at \((5,2).\)
3. Find the the equation of the line \(L\) tangent to \(f(x)=\sqrt{x}\) at \((625,25).\)
