The graph shows Jessica's weight as it compares to her age. Using the line of best fit what is the best approximation for Jessica's weight at age 10? A) 60 pounds B) 70 pounds C) 80 pounds D) 90 pounds

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

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
