Brenna's mom, Mrs. Herstone, is watching Brenna playing at the park. Some children are pushing Brenna on the merry-go-round. Mrs. Herstone decides to take some data, so she starts her stopwatch. At 0.5 seconds Brenna is farthest from Mrs. Herstone, 26 feet away. When the stopwatch reads 4.2 seconds, Brenna is closest at 12 feet away. Write a periodic function that models the distance Brenna is from Mrs. Herstone over time if the merry-go-round is spinning at a constant rate.

23

step-by-step explanation:

the answer is 62.8 cubic units

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

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.
