(10 points) Find the equation of the tangent line to x2 + 2xy - y? + x = 2 at the point (1, 2). 5. (9 points) Sand pours from a bin at a rate of 10 fts/ min and forms a conical pile whose height is always 3 times the radius. What is the rate of change of the height of the cone when the radius is 4 ft? Don't forget to include units. The volume of a cone is V = 3Tr2h where r is the radius and h is the height
