Given:
The given equation is

To find:
The vertex, focus, and directrix.
Solution:
The equation of a parabola is
...(i)
where, (h,k) is vertex,
and directrix is 
We have,

It can be written as

...(ii)
On comparing (i) and (ii), we get

Vertex of the parabola is (2,3).



Therefore, the focus of the parabola is
.
Directrix of the parabola is



Therefore, the directrix of the parabola is
.
So to find this we divide 3 by 1/2 and get 6. So, she is now only at 1/6 of her original time.1/6 is equal to .1666, and to the nearest percent that would be 17%. hope this helps and its not too late!
Answer:
C) 10,000
Step-by-step explanation:
10x1000 = 10,000
Therefore the answer is 10,000.
Step-by-step explanation:
step 1. The segment x is made up of 2 equal lines which are connected in the middle to another segment 12 units long.
step 2. the intersection of these two segments must create a 90° angle because the two lines are equal.
step 3. The lower segments are identical to the upper segments.
step 4. therefore x = 11(2) = 22.
