Consider the paraboloid f(x, y) = 16 - x2/4 - y2/16 and the point p on the given level curve of f. compute the slope of the line tangent to the level curve at p and verify that the tangent line is orthogonal to the gradient at that point. f(x, y) = 0; p(0, 16)

Aso sorry if i’m wrong

No solution : there is no number of boxes that she bought

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
