A ball is thrown downward with an initial velocity of 35 meters per second from a
cliff that is 120 meters high. The height of the ball is given by the quadratic
equation h = - 4.9t2 - 35t +120 where h is in meters and t is the time in seconds
since the ball was thrown. Find the time it takes the ball to hit the ground. Round
your answer to the nearest tenth of a second.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
