H is between Q and P. QH = 91 and QP =116 What is HP?
1 answer:
Refer to the attached image.
Since, H is between Q and P.
Since, it is given that QH = 91 and QP =116,
we have to determine the value of HP.
We can observe that the measure of segment HP is determined by subtracting the measure of segment QH from the measure of segment QP.
Therefore, HP = QP - QH
Substituting the given measures of segments QP and QH, we get
HP = 116 - 91
So, HP = 25
Therefore, the measure of segment HP is 25.

Check the picture below.
now, we know the directrix is at y = 1, and the focus point is at 1,3, well, notice the picture, the distance between those fellows is just 2 units.
the vertex is half-way between those fellows, therefore, the vertex will be at 1,2.
the distance "p", from the vertex to either the directrix or focus, is really just 1 unit. Since the focus point is above the directrix, is a vertical parabola, and it opens upwards, like in the picture, and since it opens up, the "p" value is positive, or +1.
