Answer:
Step-by-step explanation:
Standard form of a parabola with a vertical axis of symmetry:
If p > 0, the parabola opens upwards, and if p < 0, the parabola opens downwards.
From inspection of the graph:
- Vertex = (3, -1)
- Directrix = y = -3
Therefore:
- h = 3
- k = -1
- k - p = -3
Use the Directrix equation to find p
⇒ y = (k - p)
⇒ -3 = -1 - p
⇒ p = 2
Therefore the equation of the conic section is:
Rearranging in standard form :
Answer:
Yes, isosceles triangle
Step-by-step explanation:
Side lengths of 8, 8, and 4 will make an isosceles triangle.
It would look something like this:
