In 2000, the number of federal hazardous waste in state X was 12 less than three times the number of sites in state Y. Suppose there were 57 such sites in state X. Write and solve an equation that represents the number of hazardous waste sites, n, there were in state Y. IN state Y, there were federal hazardous waste sites.

While picking thirty apples, mia noticed that six apples had worm holes and had to be thrown away. what is the ratio of good apples picked to bad apples picked?

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
