If a line intersects a plane in more than one point , then the line is perpendicular to the plane

An objects motion is described by the equation d= 4sin (pi t) what will the height of the object be at 1.75 seconds?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Atriangle has side lengths of x, x+11, and 3x+5. what is the perimeter?
