Please solve for #11

10. Explicitly solve for the level curve f (9:, y) = 25 for the function f (56, y) = a: + y2 i.e. et a formula for as a function of 5': iven the condition that a: + 2 = 25 . Now 7 g y 7 g y differentiate this function to get the slope of the level curve at the point (:c, y) = (16, 3). 11. Using the same function f (:25, y) as above, obtain the slope of the level curve f (1:, y) = 25 at the point (37,31) 2 (16, 3) the easy way, that is, by using the formula we derived in class: dy : _3f (1', W 393 dm' f(:r:,y)=k 8f(7, 9V8
