The endpoints of ab are a(9,4) and b(5,-4). the endpoints of its image after a dilation are a'(6,3) and b'(3,-3). find the scale factor and explain each of your steps. this is for geometry a.

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

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

Triangles abd and ace are similar right triangles. witch ratio best explains why the slope of ab is the same as the slope of ac?
