Question 1: a waterfall has aheight of 1000 feet. a peebleis thrown upwardfrom the top of the fall with an initial velocity of 16 ft. persecond. the height H of the peeble after 1 second isgiven by the equation H=16t^2 +16t+1000. how long afterthe peebleis thrown will it hit theground? _____________ seconds after itsthrouwn to hit the ground.
Question 2: a ball is throwndownward fromthe top of a 200 ft. building with an initialveloscity of 24 ftper second. the height of the ball Hafter 1 second is given by the equationH=-16t^2-24t+1200? ______ seconds it will take to hitground
Question 3: the number of coffeeshops in a certain country can be modeled by the quadratic functionf(x) - 105x^2 + 746x + 3251 where f(x) is the number of coffeeshops and x is the number of years after 2000. completeparts a and b.
