The answer choice which describes the function is; Choice B; neither symmetry about the y-axis nor has order 2 rotational symmetry about the origin.

<h3>What is rotational symmetry?</h3>

Rotational symmetry, otherwise termed radial symmetry, is the characteristic of a shape when it looks the same after some rotation by a partial turn. On this note, since the function represents a quartic graph, it follows that the function has neither symmetry about the y-axis nor has order 2 rotational symmetry about the origin.

Therefore, the function f(x) = −4x⁴ + 3x³ − 2x² − x + 5 is neither symmetry about the y-axis nor has order 2 rotational symmetry about the origin.

What is the length of AB?<br> O A. 9<br> O B. 18<br> O C. 48<br> D. 6
insens350 [35]
<h3>Answer:  A.  9</h3>

=====================================================

Explanation:

Draw in the segments AO and OC.

Triangle ABO is congruent to triangle CBO. We can prove this through the use of the HL theorem. HL stands for hypotenuse leg.

Since the triangles are congruent, this means the corresponding pieces AB and BC are the same length.

Then we can say:

AB+BC = AC .... segment addition postulate

AB+AB = AC .... plug in BC = AB

2*AB = AC

2*AB = 18

AB = 18/2 .... divide both sides by 2

AB = 9

In short, the chord AC is bisected by the perpendicular radius drawn in the diagram. So all we do is cut AC = 18 in half to get AB = 9.

We're told (5,-2) is on the line, that's x=5, y=-2


First one y-5 = -7, (x+2)/3=7/3, not equal


Second one y+5=3, (x-2)/3=1, not equal


Third one y+2=0, (x-5)/3=0, TRUE, equal


Fourth one, y-2=-4 (5+5)/3=10/3, not equal



Answer: third choice y+2 = (1/3)(x+5)

Which is the solution to the inequality?
FinnZ [79.3K]

Answer:

\Huge \boxed{x

Step-by-step explanation:

To solve this problem, first you have to isolate it on one side of the equation.

First, subtract 1/4 from both sides.

1/4+x-1/4<5/6-1/4

Solve.

5/6-1/4=7/12

Therefore, the correct answer is A. x< 7/12.

Use the information to answer the questions. In triangle ABC, a = 11 in., m&lt;B=70, and c=9 in. Which information about the tri
nataly862011 [7]
Answer:
SAS

Explanation:
In triangle ABC:
a would be the side opposite to angle A
c would be the side opposite to angle C

Combining the given, we would fine that we have the measures of two of the sides and the measure of the angle included between them.
This means that we have SAS information.

Check the attached image for visual illustration.

Hope this helps :)
