Using calculus, it can be shown that if a ball is thrown upward with an initial velocity of 80 ft/s from the top of a building 252 ft high, then its height h above the ground t seconds later will...

D= {zIz ≥3} E= {zlz <5} Write F U H and F n H using interval notation. If the set is empty, write Ø

mathematically, h≥0. Negatives are not allowed under a square. contexually, h≥0. Hopefully, the roller coaster is always above ground.
