Rex, Paulo and Ben are standing on the shore watching for dolphins. Paulo sees one surfacr directly in front of him about a hundred feet away. Find the distances between Rex, Paulo and the dolphin. Thr angles between Rex Ben and the dolphin are marked on the diagram. Part I: using triangle bcd, find the distance between rex and between rex and paulo. Assume the distance between Paulo and the dolphin is exactly 100 feet. Round your answer to the nearest one decimal place. Show your work (4 points, 2 points each distance

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
