The level curves of the surface z = x^2 + y^2 are circles in the xy-plane centered at the origin. without computing the gradient, what is the direction of the gradient at (- 3,- 5) and (5,2) (determined up to a scalar multiple)?

Where’s the problems ? ?

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
