Do the side lengths 4, 8, and 10 form a triangle? Select the correct answer and reasoning. Question 18 options: A) Yes, because the sum of any two side lengths is greater than the third side length. B) Yes, because the sum of all three side lengths is greater than 20. C) No, because the third side length is greater than the sum of the other two side lengths. D) No, because 4 + 8 is greater than 10.

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
