Find the expression when a=-3 and b=-1: A^2-b^2=

Venus is about 108 kilometers from the sun. saturn is about 109 kilometers from the sun. about how many times farther from the sun is saturn than venus?

What is the sum of these mixed numbers 2 1/8 + 4 3/8

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
