Answer:

  x = 4

Step-by-step explanation:

The vertex is on the line of symmetry. The zeros are located equidistant from the line of symmetry, which is ...

  x = (2 + 6)/2 = 4

The x-coordinate of the vertex is x=4.

if u have a 2 digit reapeating decimal how do u convert it into a fraction ex.) 0.023 but 23 ia reapeting over and over how do u
Anna35 [415]

Almost 60 years after taking my last math class, I discovered
how to turn a repeating decimal into its equivalent fraction.

-- Take the set of digits that repeats, no matter how many digits there are.
Write them as the numerator of a fraction.

-- For the denominator, write the same number of '9's.

-- If it's possible and you feel like it, simplify (reduce) the fraction.


You have 0.023 with the 23 (two digits) repeating forever.

-- Write the 23 (two digits) as the numerator.

-- Write 99 (two digits) as the denominator.

Now you have the fraction  23 / 99 .  It can't be reduced.

You actually had 0.0... before the repeating part. That just
means that the fraction has been divided by 10.  The real
equivalent fraction is  23 / 990 .  (Which also can't be reduced.)

After so many years not knowing how to do it, this still blows my mind. 
Just now, I punched " 23/990 "into my calculator, and stared in wonder
and amazement when " 0.023232323 " came up.

What is 1/8th of a full rotation?
Hitman42 [59]
Well a full rotation is 360 degrees so what you would do is 1/8 of 360 and to do this you would divide 360 by 8 which is 45 and then you would times by 1 so the answer is 45 degrees. To make this simpler if you have a circle and split it into 4 each segment is 90 degrees and to get an extra 4 you'd divide each segment again by 2 and 90/2 is 45
