Describe the transformations of the graph of y graph of y= - (x-2)^2-1
that will produce the
O A. Shift up 2 units, left 1 unit, then reflect across the xaxis
OB. Shift right 2 units, reflect across the xaxis, then down 1 unit
O C. Shift down 2 units, reflect across the yaxis, then right 1 unit
OD. Shift left 2 units, down 1 unit, then reflect across the yaxis

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
