Given:
The focus of the parabola is at (6,-4).
Directrix at y=-7.
To find:
The equation of the parabola.
Solution:
The general equation of a parabola is:
...(i)
Where, (h,k) is vertex, (h,k+p) is the focus and y=k-p is the directrix.
The focus of the parabola is at (6,-4).
On comparing both sides, we get
...(ii)
Directrix at y=-7. So,
...(iii)
Adding (ii) and (iii), we get
Putting in (ii), we get
Putting 
in (i), we get
Therefore, the equation of the parabola is .

Answer:
In this particular case, Circle M has circumference 11π, or approximately 34.6 units.
Step-by-step explanation:
The circumference of a circle of diameter d is C = πd.
In this particular case, Circle M has circumference 11π, or approximately 34.6 units.
You would take half of the x term...and square it
so half of 8 is 4....4^2 = 16
u would add 16 to each side
