a parabola can be represented by the equation x2 = 2y.
what are the coordinates of the focus and the equation of
the directrix?
focus: (0,8); directrix: y=-8
focus: (0,1); directrix: y = -1
focus: (8,0); directix: x = -8
o focus: (.9); directrix x = -1

a

step-by-step explanation:

where is the option given

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.

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
