Sophia and London were Worked at a dry cleaners ironing shirts. Sophia Ken iron 40 shirts per hour, and London can iron 25 shirts per hour .Sophia and London worked a combined 11 hours and ironed 365 shirts shirts. write a system of equations that could be used to determine the number of hours Sophia and London worked and the number of London worked. You find the very abilities that you use to write the system.

1foot = 12 inches; 1 yard = 3 feet

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
