During batting practice, two pop flies are hit from the same location, 2 s apart. The paths are modeled by the equations h = -16
t2 + 56t and h = -16t2 + 156t - 248, where t is the time that has passed since the first ball was hit. possible answers: A :Isabel is correct because the y-intercept of line B is (0, 9) and the value of y when x = 0 in parabola A is 9. B: Isabel is correct because the y-intercept of line B is (9, 0) and the value of x when y = 0 in parabola A is 9. C: Isabel is incorrect because the point of intersection between line B and parabola A that can be determined is the y-intercept of the equations, not the vertex. D: Isabel is incorrect because the point of intersection between line B and parabola A that can be determined is the x-intercept of the equations, not the vertex.
