The line of symmetry for a parabola does not always contain which point?

Mathematics
1 answer:
antoniya [11.8K]4 years ago
5 0
A parabola's axis of symmetry always goes through the vertex of the parabola. In other words, it is a vertical line that goes through the x-coordinate of the vertex. Therefore, the equation of the axis of symmetry for this parabola is x = 0.

Someone pls help I need this like now pls lots of points and brainliest
Serjik [45]

Answer:

  • See below

Step-by-step explanation:

<h3>#7</h3>
  • 5⁵(16²5³)³ = 5⁵(2⁴)³(5³)³ = 5⁵2¹²5⁹ = 5¹⁴2¹²
<h3>#8</h3>
  • (8⁴5³/8⁵)² = (5³/8)² = (5³)²/(2³)² = 5⁶ / 2⁶
<h3>#9</h3>
  • (5⁸3⁷/5⁴)¹⁰ = (5⁴3⁷)¹⁰ = (5⁴)¹⁰(3⁷)¹⁰ = 5⁴⁰3⁷⁰
<h3>#10</h3>

<u>Multiplying powers with same base:</u>

  • a^b*a^c=a^{b+c}
  • Same base with powers added up

<u>Multiplying powers with same exponent but different base:</u>

  • a^b*c^b=(ac)^b
  • Same exponent with bases multiplied

Need help with one and two
adoni [48]

Answer:

(1) is a function, surjective aka onto,

not bijective aka one to one.

domain is {3,6,12,14,20,22},

range is {4,15,8,11}. More elements in domain means it can't possibly be one to one.


(2) is a relation but not a function, although its inverse is a function. There are fewer elements in the domain than the range, so a function could not be onto but would have to be into or injective.


The relation you get by restricting the domain to {1,19} is a function, injective, so that the image of the domain is a proper subset of the range.

Find the common difference of the arithmetic sequence 1,-1, -3, ...
frutty [35]
Answer:
-2

Explanation:
The common difference of a sequence is the difference between consecutive terms. To find it, we subtract two consecutive terms.

1, -1, -3

1 and -1 are consecutive terms.
-1-1=-2

Therefore, the common difference is -2.

We can also try the same thing with -3 and -1, since they are also consecutive terms.

-3-(-1)
=-3+1
=-2

I hope this helps! Please comment if you have any questions.
