If a figure has been dilated by a scale factor of 2, which transformation could be used to prove the figures are similar using the aa similarity postulate?
a reflection to map at least two sides of the image to two sides of the pre-image.
a series of dilations to map at least two angles of the image to two angles of the pre-image.
a rotation to map at least two sides of the image to two sides of the pre-image.
a series of translations to map at least two angles of the image to two angles of the pre-image.

Find the height of a square pyramid that has the volume of 32 ft.³ and a base lengthof 4 feet

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:

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).
