Find the flux of the following vector fields across the given surface with the specified orientation. you may use either an explicit or parametric description of the surface. f=〈x, y,z〉across the slanted face of the tetrahedron z=10−2x−5y in the first octant; normal vectors point upward.

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.
