1. Alex throws a football to Domenic. After 3s, the football is at its highest point which is 18m. It lands
on the ground 7s after it was originally thrown. If the flight of the football follows a parabolic path,
find the equation of the relation that describes the path of the football.

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
