Ten male senators are on their way to the clinton inaugural ball. a crowd of disgruntled taxpayers attacks them with volley of snowballs, knocking each seneator's top hat to the ground. a page retrievs the hats and hands one to each senator-but without checking to see who owns which one. what is the exact probability that exactly nine senators will recieve their own hats?

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

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

Is the figure congruent? yes or no?
