Answer:
<em>134456</em>
Step-by-step explanation:
= 7 · 7 · 7 · 7 · 7 · 7
Therefore, = 117,649
= 7 · 7 · 7 · 7 · 7
Therefore, = 16,807
So, +
= <em>134456</em>

We have the equation
Let's complete the square, to do it let's add and subtract 25 on the right side
Now we can have y in function of x
Now we can already identify the vertex because it's in the vertex form:
Where the vertex is
As we can see, h = 5 and k = -2, then the vertex is
Now we can continue and find the focus, the focus is
We have a = 1/20, therefore
The focus is
And the last one, the directrix, it's
Then
Hence the correct answer is: vertex (5, -2); focus (5, 3); directrix y = -7
