Which system about this figure is true?

jok3333 [9.3K]

Answer:

1) It has rotational symmetry with an angle of rotation of 90 degrees.

TRUE, it has rotational degree, FALSE, angle of rotation is 180 degrees

2)It has no reflection symmetry. FALSE

3)It has reflection symmetry with many planes of symmetry. TRUE

4) It has no rotational symmetry. FALSE

Step-by-step explanation:

Rotational Symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appear the same.

Symmetry Order = Number of turns it takes to get to its similar position.

Reflected Symmetry : When a line is drawn which divides the shape in to two equal halves it is called reflective symmetry.

Consider the given figure:

1) It has rotational symmetry with an angle of rotation of 90 degrees.

TRUE, it has rotational degree.

FALSE, it regains its identical shape in 90 degrees, it is in 180 degrees.

2)It has no reflection symmetry.

FALSE, the given figure has reflection symmetry along both horizontal and vertical axis.

3)It has reflection symmetry with many planes of symmetry.

TRUE, it has inflectional symmetry in Horizontal as well a in vertical plane.

4) It has no rotational symmetry.

FALSE, it has a rotational symmetry of ORDER 2

Find the distance between -3 and 4. A) -12 B) -7 C) -1 D) 7

bonufazy [111]

The answer is 7 because add them to see the distance since it’s both positive if you count the distance it is away from zero so 3+4=7

Which graph represents the function f(x)=3x-2/x-2

Marta_Voda [28]

ANSWER

The last graph is the correct answer

EXPLANATION

The function,
$y = \frac{3x - 2}{x - 2}$ is a rational function.

This rational function has a vertical asymptote

at where the denominator is zero.

That is,
$x - 2 = 0$

This means that, the vertical asymptote occurs at

$x = 2$

The graph also has a horizontal asymptote at,

$y = \frac{3}{1}$

Thus, the horizontal asymptote occurs at
$y = 3$

At x-intercept,
$f(x) = 0$

This implies that,

$\frac{3x - 2}{x - 2} = 0$

$\Rightarrow \: 3x - 2 = 0$

$3x = 2$

$\Rightarrow \: x = \frac{2}{3}$

The graph cuts the x-axis at,

$( \frac{2}{3} ,0)$

At y-intercept,

$x = 0$

This implies that,

$f(0) = \frac{3(0) - 2}{0 - 2} = \frac{ - 2}{ - 2} = 1$

The graph cuts the y-axis at,

$(0,1)$

The graph that satisfy all the above conditions is the last one.
