Please Help Me. An antenna is 5m high and 150 meters from the firing place. Suppose the path of the bullet shot from the firing place is determined by the equation y=-1/1500x^2 + 2/15x, where x is the distance (in meters) of the bullet from the firing place and y is its height. Will the bullet go over the antenna? If yes/no, show your justification.

Substitute 150 for x and solve for y and see if y exceeds 5.

According to my calculation the bullet cuts the wire.  I guess that would mean a no.
