Workers preparing for the city's Fourth of July celebration shoot an object straight up with an initial velocity of 210 ft/s2 from a height of 3 feet above the ground. Will the object reach a height of 670 feet 0, 1, or 2 times? Use the equation h=16t^2+vt+c where v is the initial velocity in feet per second and c is the initial height in feet of the object above the ground. Use the discriminant to explain your answer. Group of answer choices a) 2 times; The discriminant is positive, so the equation has two solutions. b) 0 times; The discriminant is negative, so the equation has no solutions. c) Cannot determine. There is no discriminant in the equation. d) 1 time; The discriminant is zero, so the equation has one solution.
