we know that
The function of a vertical parabola written in vertex form is equal to
where
(h,k) is the vertex of the parabola
in this problem we have
substitute in the equation
Find the value of the coefficient a
Substitute the value of x and y of the point 
in the equation
The equation is equal to
----> is a vertical parabola open downward
Answer: -30
Step-by-step explanation:
My answer is correct because, All you have to do is subtract all the numbers by 11 and the one that has the sum -19 is the correct choice. In this case -30 does and we can make sure were orrect by subtracting 11 by -19 and that equals -30.

Answer:
1/n^12 or n^-12
Step-by-step explanation:
=n^-10 / n^2
=1/n^10 / n^2
=(1/n^10) *(1/n^2)
=1/n^12
Answer:
30.4m
Step-by-step explanation:
Diameter(D) = 2r (radius)
D = 9.7m
r = 9.7m / 2
= 4.85m
C = 2πr
= 2π × 4.85m
= 30.47344873982099m
rounding - Leave it as is if the digit in the tenth is 4 or lower
- round it up if it's 5 or higher.
~~ 30.4m
