a golf ball is hit into the air. the path of the golf ball is represented by the function h = 40t - 5t2 , where h is the height of the ball in feet and t is the time in seconds. how many seconds will it take the golf ball to reach a height of 60 feet?

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?
