2. find the equation of the tangent plane to the sphere 2 + y2 2 = 6 at p (1,1,2) three different ways: (a) using level set methods, (b) using the parametrization r(x, y) (x, y, v6-x2- and (c) using graph methods, f(x, y) v6-2-y2 =

George has a triangle-shaped garden in his backyard. he drew a model of this garden on a coordinate grid with vertices a(4, 2), b(2, 4), and c(6, 4). he wants to create another, similar-shaped garden, a′b′c′, by dilating triangle abc by a scale factor of 0.5. what are the coordinates of triangle a′b′c′?
