A traffic jam has slowed down traffic on the highway. After half an hour, cars have only traveled 15 miles. If the traffic stays at this rate, how far will the cars have moved after 1 hour and a half.

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:

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then
