Graph the image of square CDEF after a reflection across the x-axis​

Mathematics
1 answer:
Rina8888 [55]3 years ago
5 0

Answer:

If you have a general point (x, y), and you reflect it across the x-axis, the coordinates of the new point will be:

(x,-y)

So we only change the sign of the y-component.

Now, if we do a reflection across the x-axis of a whole figure, then we apply the reflection to all the points that make the figure.

Then, we could just apply the reflection to the vertices of the square, then graph the new vertices, and then connect them, that is equivalent to graph the image of the square after the reflection.

The original vertices are:

C = (-3, 7)

D = (0, 7)

E = (0, 10)

F = (-3, 10)

Now we apply the reflection, remember that this only changes the sign of the y-component, then the new vertices are:

C' = (-3, -7)

D' = (0, -7)

E' = (0, - 10)

F' = (0, - 10)

Now we need to graph these points and connect them to get the reflected figure, the image can be seen below.

Answer:

1009

Step-by-step explanation:

0,25 x 2018 = 504,5

20,18 x 25 = 504,5

504,5 + 504,5 = 1009

-3x + 2y = 21<br> -4x + y = 23
Nady [450]

Answer:

2y = 3x + 21

y = 1.5x + 10.5

plug in, in the second equation

- 4x + (1.5x + 10.5) = 23

-4x + 1.5x + 10.5 = 23

-2.5x + 10.5 = 23

-2.5x = 12.5

x = 12.5/-2.5 = -5

y = 1.5 (-5) + 10.5 = 3

x = -5

y = 3

1. Here is a circle. Points A, B, C, and D are drawn, as
Darya [45]

The area of the circle is approximately 50

<h3>Areas</h3>

The area of a shape is the amount of space occupied by the shape

<h3>Area of circle</h3>

Given the three radius of the circle, the area of the triangle is calculated using:

Area = \pi r^2

From the figure, we have:

AD = 4 --- the radius

So, we have:

Area = \pi r^2

Area = 3.14 \times 4^2

Area = 50.24

Approximate

Area = 50

Hence, the area of the circle is approximately 50

AB=8 and CD =40 find EB ,BC and AC
SIZIF [17.4K]

Answer:

EB=20, BC=8, AC=16

Step-by-step explanation:

The symbols indicate that:

AB=BC  and AE=ED

EB and CD are parallels

AB=BC=8

AC= AB+BC

AC= 8+8

AC=16

To find EB we can use the Cosine Law

For the upper triangle x=∡EAB:

EB^2 = AB^2 + AE^2 -2*AB*AE*Cosx

AB*AE*Cosx= -(EB^2-AB^2 - AE^2)/2 (Part I)

For de big triangle:

DC^2= AC^2+AD^2 -2AC*AD*Cosx

Also:

AC=2*AB

AD=2*AE

DC^2= (2*AB)^2 + (2*AE)^2 -2(2*AB)(2*AE)*Cosx

DC^2= 4*AB^2 +4*AE^2- 8*AB*AE*Cosx

AB*AE*Cosx =-(DC^2-4*AB^2 -4*AE^2)/8 (Part II)

Part I= Part II

-(EB^2-AB^2 - AE^2)/2= -(DC^2-4*AB^2 -4*AE^2)/8

Extracting EB:

EB^2=DC^2/4

EB=DC/2

EB=40/2

EB=20
