Will mark brainliest and rate 5/5 Suppose a plane intersects a cube through three intersecting edges
How can you ensure that the triangle cross section is an equilateral triangle?
1. The corner of the cube can be sliced off such that the three verticies of the triangle are at the same distance from the corner of the cube
2. The corner of the cube can be sliced off such that the plane intersects the base
3. The corner of the cube can be sliced off such that the plane is perpendicular to the base

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

Whats the name of the vertical axis
