Kenzie has three beakers of water. She adds 1.0g of salt to the first beaker. When she stops stirring, the salt can no longer be seen. She adds 1.0g of sand to the second beaker. When she stops stirring, the sand sinks to the bottom. She adds 1.0g of blue powder to the third beaker. The water and powder start to form bubbles which cause the mixture to foam at the top and some of the blue powders settles to the bottom. 8) Which beaker demonstrated chemical reaction? How is this different from the creation of a solution? Explain your answer.

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
