1. Let f (x) = kx^2 +c. a) Find x0, in terms of k such that the tangent lines to the graph of f at (x0, f(x0)) and (-x0, f(-x0)) are perpendicular.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
