The equation of a parabola is:
![y = ax {}^{2} + bx + c](https://tex.z-dn.net/?f=y%20%3D%20ax%20%7B%7D%5E%7B2%7D%20%20%2B%20bx%20%2B%20c)
If a>0, then the parabola opens up;
If a<0, then the parabola opens down.
The coordinates of focus are:
Answer:
Step-by-step explanation:
I encourage my Geometry students to be a bit more thorough than this proof table allows, but we can get it done anyway.
1. ∠2≅∠4 Given
2. m║n If corresponding angles are congruent, then the
lines cut by a transversal are parallel
3. ∠1≅∠3 Alternate interior angles are congruent
Question #1:
a)
(4, 2)
Both of these are positive, and when x and y are both positive they're both in Quadrant 1.
b)
(x + 1, y - 5)
Add 1 to 'x', subtract 5 from 'y':
(4 + 1, 2 - 5)
(5, -3)
x is positive and y is negative, that means this will be in Quadrant 4.
c)
Reflection Across y-axis:
(-x, y)
Multiply -1 to 'x':
(5 * -1, -3)
(-5, -3)
Both of these are negative, if both x and y are negative it's located in Quadrant 3.
Question #2:
No, that can't tessellate a plane. We can't cover up space so there are no overlaps or gaps.
