In the diagram lines r and v are perpendicular. The quadrilateral KBMW is shown. Perform the sequence of transformations listed. Then, draw the
resulting quadrilateral "B"M"W".
Reflect quadrilateral KBMW over line v.
Then reflect quadrilateral K'B'M'W' over liner.

The double reflection over line v and then liner will be the same as a rotation of

In the past, professional baseball was played at the astrodome in houston, texas. the astrodome has a maximum height of 63.4 m. the height of a baseball t seconds after it is hit straight up in the air with a velocity of 45 ft/s is given by h = -9.8t2 + 45t + 1. will a baseball hit straight up with this velocity hit the roof of the astrodome? use the discriminant to explain your answer.
