round up to nearest 1/100th
8% of 85,360 =
5 ½% of 2,100 = 115.50
i did one but not sure if this is correct. i had another tutor on cheg did it but it is wrong

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

Match each inequality to the number line that represents its solution

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 5x^2 + 10x
