Which inequality represents this situation? kendra is making a large salad for a party. she buys lettuce for $2.25 per pound and tomatoes for $2.65 per pound. she spends at least $8. let x represent the number of pounds of lettuce that kendra buys. let y represent the number of pounds of tomatoes that kendra buys. 2.25x 2.65y> 8 2.25x 2.65y≥8 2.25x 2.65y≤8 2.25x 2.65y< 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
