I will mark you brainliest if you get the question correct!!! Find the difference.

A climber starts descending from 563 feet above sea level and keeps going until she reaches 50 feet below sea level. How many feet did she descend?

She descended feet.

Solve the system of equations. y= 2x y= x^2 - 15

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
