HU PLEASEEE ABC will undergo two transformations to give ABC which pair of transformations will give a different image of ABC if the order fo the tranformations is reversed A. a rotation 90 counterclockwise about the origin followed by a reflection across the y-axis b. a translation 5 units down followed by a translation 4 units to the right C. a reflection across the x-axis followed bt a reflection across the y-axis d. a rotation 180 clockwise about the origin followed by a reflection across the y axis

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:

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.

Can someone, me with this.i really need with this
