Find the surface area of the composite solid. a. 446mm squared b. 464mm squared c. 468mm squared d. 486mm squared

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

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

X2 + y 2 = 36 x + y = 6 solve the system of equations.
