If DE = 2.5 ft, what is FG? How do you know? If the measure of angle E is 129 degrees, what is the measure of angle G? How do you know? What happens to the measure of angle D as the measure of angle E increases or decreases? Explain.​

Volume of cylinder with a radius of 8cm and height of 25 cm

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
