6. you are purchasing cotton swabs that come in 2 different
sized containers. one box contains 300 swabs for $2.99 and
the other box is specially marked at 30% more swabs for the
same price. how much will you save per swab by buying the
larger box?

Np4=12np2 with clear explanation.

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

Ineed if you could explain and give me the answer you! this needs done
