Asoccer player kicks the ball to a height of 1 meter inside the goal. the equation for the height, h, of the ball at time, t, is h=-4.9t^2-5t+2. find the time the ball reached the goal.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
