Answer the question or provide the appropriate response.A toy rocket is launched upward from ground level with an initial velocity of 83 feet per second. Describe how you could determine graphically whether the rocket will reach a height of 35 feet, and, if so, at what time(s) this will happen.
A. Graph y1 = -16x2 + 83x and y2 = 35. If the graphs intersect, find the x-coordinates of the intersection point(s).
B. Graph y = -16x2 + 83x + 35. If the graph has any x-intercepts, find them.
C. Graph y1 = 16x2 + 83x and y2 = 35. If the graphs intersect, find the x-coordinates of the intersection point(s).
D. Graph y1 = -16x2 + 83x and y2 = 35. If the graphs intersect, find the y-coordinates of the intersection point(s).
