You and a friend are hiking in the mountains. you want to climb a ledge that is 29 feet above you. the height of the grappling hook you throw is given by the function h(t)=16t^2+32t+5. use the discriminant to figure out if the grappling hook will reach the ledge. explain.

i think the answer is d im not sure

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.
