Katherine makes bracelets at a rate represented by the algebraic equation y = 4x where x is the
number of days, and y is the total number of
bracelets made. Katherine also makes necklaces
at the rate shown in the graph.
Necklaces Made
Days
Based on the information, what is the difference
in the rate of change between the two
functions?
(Write the answer as a fraction in lowest terms.)

Add or subtract polynomial : –12qr? +13rq?

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

Aremote-controlled boat can travel at 4 feet per second in calm water. the boat traveled 48 feet with the current, and then it traveled 16 feet against the current in the same amount of time. how fast is the current?
