I tried many thigns with this one:(adsbygoogle = window.adsbygoogle || []).push({});

Determine the equation of the line that is perpendicular to the tangent to [tex]y=5x^2 at (1,5)[/tex]

What I did was use the formula for instantaneous rate of change finding the equation of the secant.

[tex](5x^2-5)/(x-1)[/tex]

from there I found that the slope of the tangent is about 10 and from there i'm lost
