Aparatrooper jumps from a plane at an altitude of 4500 ft and descends at the rate of 20 ft/sec. what is the formula for the paratrooper’s height, h, above the ground after t seconds? a. 4072-01-01-03-00_files/i0130000.jpg c. 4072-01-01-03-00_files/i0130001.jpg b. 4072-01-01-03-00_files/i0130002.jpg d. 4072-01-01-03-00_files/i0130003.jpg

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:

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
