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

The G.CD of the number is 17 and the L.C.M is 140,If one of the number is 20, Find the other number

Alik [6]

Answer:

HCF Of two nos. is 17

Let another no. be x

we know that HCF ×LCM = Product of two numbers

17×140=20×(x)

20x=2380

x =2380/20

x=119

The other no. is 119

Let II be the tangent plane to the graph of f(x, y) = 8 – 2x^2 – 3y^2 at the point (1, 2,-6). Let S, x² + y^2 + z = 4 be another

stealth61 [152]

Let $F(x,y,z)=f(x,y)-z$ . The tangent plane to $f(x,y)$ at (1, 2, -6) has equation

$\nabla F(1,2,-6)\cdot(x-1,y-2,z+6)=0$

We have

$\nabla F(x,y,z)=(-4x,-6y,-1)\implies\nabla F(1,2,-6)=(-4,-12,-1)$

Then the tangent plane has equation

$(-4,-12,-1)\cdot(x-1,y-2,z+6)=0\implies -4(x-1)-12(y-2)-(z+6)=0\implies 4x+12y+z=22$

Let $g(x,y)=4-x^2-y^2$ , and $G(x,y,z)=g(x,y)-z$ . The tangent plane to $S$ at a point $(a,b,c)$ is

$\nabla G(a,b,c)\cdot(x-a,y-b,z-c)=0$

We have

$\nabla G(x,y,z)=(-2x,-2y,-1)\implies \nabla G(a,b,c)=(-2a,-2b,-1)$

so that this plane has equation

$(-2a,-2b,-1)\cdot(x-a,y-b,z-c)=0\implies2ax+2by+z=2a^2+2b^2+c$

In order for this plane to be parallel to the previous plane, we need to have

$\begin{cases}2a=4\\2b=12\end{cases}\implies a=2,b=6\implies g(a,b)=c=-36$

so the point we're looking for is (2, 6, -36).
