The height of a ball above the ground after it is thrown upwards (initial velocity) at 40fps can be modeled by the function h(t)=-16t^ 2 +v 0 t+h 0 ( pts) a) At what time(s) is the ball 15 feet above the ground? b) How long will the ball stay in the air?

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.
