Propellants are chemicals used to power rockets, much like gas is used to power cars. A rocket scientist has been using Propellant X in her rockets for many years, but is interested to see if Propellant Z will cause her rockets to rise higher into the air. The scientist builds a rocket that uses Propellant Z. A proper control for the experiment would be an identical rocket that uses which of the following? (SC.7.N.1.1) A. Propellant X B. Propellant Z C. No propellant D. A mixture of both Propellant X and Propellant Z

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
