During a walk-a-thon, Bridget's time in hours, t, and distance in miles, d, are related by the equation 1/2d = t. A graph of this equation includes the point (10, 5). What does the coordinate (10, 5) mean in relation to the walk-a-thon?

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

Solve the equation w^3 = 1,000 i honestly dont know how to punch this into a calculator pls

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?
