The graph represents an object that is shot upwards from a tower and then falls to the ground. 1. How tall is the tower from which the object was shot?

2. When did the object hit the ground?

3. Estimate the greatest height the object reached and the time it took to reach that height. I indicate this situation on the graph.

1: The tower is around 93 meters tall. 2: The object hit the ground at 6 seconds. 3: 3 seconds to get to about 93 meters up.

Step-by-step explanation:

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

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.
