Question 1170671: A parabolic arch of a tunnel that is 4 meters wide and 1.5meters tall at the centre. The left edge of the tunnel opening is the origin. The roots are (0,0) and (0,4)
The parabola is 1.5 meters tall at the centre. The vertex is at (2,1.5)
Lamps which are 25 cm long are then installed in the tunnel which narrows the opening. How do you illustrate the opening of the tunnel reduced by the lamps on the same set of axes Answer by ikleyn(52788) (Show Source):
