Using the given information, give the vertex form equation for each parabola.
ollegr [7]

Answer:

Step-by-step explanation:

If you plot this point and the directrix on a coordinate plane, you can see that the directrix is 1/4 of a unit below the vertex.  Since, by nature, a parabola opens in the direction opposite the directrix and "hugs" the focus, this is a positive x-squared parabola (meaning it opens upwards).  The formula for this type of a parabola is, in vertex form,

4p(y-k)=(x-h)^2

where p is distance (in units) between the vertex and the directrix and h and k are the coordinates of the vertex.  For us, p = .25, h = 7, and k = -6.  Filling in our formula:

4(.25)(y+6)=(x-7)^2

Simplify the left side to

1(y+6)=(x-7)^2 which simplifies, in its entirety, to

(x-7)^2-6=y

Answer:

The answer to your question is: midsegment = 35 units

Step-by-step explanation:

Use the Thales' theorem

                          \frac{3x + 55}{6x + 5} = \frac{86}{43} \\

                          43( 3x + 55) = 86( 6x + 5)

                          129x + 2365 = 516x + 430

                          129x - 516x = 430 - 2365

                          -387x = -1935

                           x = -1935 / -387

                           x = 5

Midpoint length = 6(5) + 5

                           = 30 + 5

                          = 35 units
