Count from the origin to the center of the parabola. You will notice that there are 4 units.
So, the axis of symmetry is the line x = 4. The equation x = 4 cuts the parabola exactly in half.
Answer:
Step-by-step explanation:
Sum of the interior angles of polygon = (n-2) * 180
= (4 - 2) *180 = 2 *180 = 360
n is no of sides of the polygon
9514 1404 393
Answer:
53/99
Step-by-step explanation:
When an n-digit repeat begins at the decimal point, the repeating digits can be placed over an equal number of 9s to make a fraction. Sometimes, that fraction can be reduced to lower terms.

__
If the repeat does not start at the decimal point, the conversion can be done as follows.
For a number x with a decimal fraction that has n digits repeating, multiply by 10^n, subtract x and then divide by (10^n -1).
The fraction will be ...
(x·10^n -x)/(10^n -1) . . . where x has n repeating digits in the decimal fraction
Here, that looks like ...

Answer:
idk if it's right and i'm really sorry if it isn't
∴ x=
Step-by-step explanation:
f(x)=3
fx=3
÷f on both sides
x=
