The third side is described in relation to one of the equal sides, so let x = the length of one of the equal sides. Which equation models the problem? x + x + (5 – 2x) = 23 x + x + (2x – 5) = 23 x + x + (2x + 5) = 23 x + (2x – 5) + (2x – 5) = 23

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
