Courtney started a pattern with 4 and used the rule​ "Add 10​." What are the first 5 numbers in​ Courtney's pattern? Describe the numbers in the sequence.

Find all the values of x that make 0.1x + 0.25(102 - x) < 17.10 true.

What is the quadric regression equation that fits these data

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
