Help me pls I will give free points and brainliest just help first

Franco wants to double the volume of the cone. what should he do?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.
