Answer: c. 8(y-6) = (x-2)^2</h3>
Explanation:
The directrix is horizontal, so the axis of symmetry is vertical. We'll have an x^2 term. The vertical distance from y = 4 to y = 8 is 4 units. Cut this in half to get 2, which is the focal distance p = 2.
The point (2,4) is directly below (2,8), and the point is on the directrix. The midpoint between (2,4) and (2,8) is (2,6). This is the vertex.
(h,k) = (2,6)
4p(y-k) = (x-h)^2
4*2(y-6) = (x-2)^2
8(y-6) = (x-2)^2
Answer:
8
Step-by-step explanation:
- An Equilateral Triangle (3 sides) has 3 Lines of Symmetry
- A Regular Pentagon (5 sides) has 5 Lines of Symmetry
- A Regular Hexagon (6 sides) has 6 Lines of Symmetry
- A Regular Heptagon (7 sides) has 7 Lines of Symmetry
- A Regular Octagon (8 sides) has 8 Lines of Symmetry
Answer: 2 3/4 as an improper fraction would be B. 11/4
