Answer:

C) AB = BC = CD = DA = 2√5

Corrected question:

Consider a shape with vertices A(1, 4), B(3, 0), C(1, −4), and D(−1, 0) on the coordinate plane. 1) Which proves that the shape given by the vertices is a rhombus? A) AB = BC = CD = DA = 10 B) AB = BC = CD = DA = 15 C) AB = BC = CD = DA = 2√5 D) AB = BC = CD = DA = 3√5

Step-by-step explanation:

Given;

Vertices

A(1,4)

B(3,0)

C(1,-4)

D(-1,0)

We need to determine the Length of sides;

AB,BC,CD,DA

Length = √((∆x)^2 + (∆y)^2)

For

AB = √((3-1)^2 + (0-4)^2) = √(4+16) = √20 = 2√5

BC = √((1-3)^2 + (-4-0)^2) = √(4+16) = √20 = 2√5

CD = √((-1-1)^2 + (0--4)^2) = √(4+16) = √20 = 2√5

DA = √((1--1)^2 + (4-0)^2) = √(4+16) = √20 = 2√5

Which shows that;

AB=BC=CD=DA=2√5

For a rhombus, all sides are equal.

Therefore, AB=BC=CD=DA=2√5, proves that the shape given by the vertices is a rhombus.

Answer:

C) AB = BC = CD = DA = 2√5

Step-by-step explanation:

Given

A(1, 4)

B(3, 0)

C(1, −4)

D(−1, 0)

We get the distance between point A and point B

AB = √((3-1)²+(0-4)²) = √20 = 2√5

BC = √((1-3)²+(-4-0)²) = √20 = 2√5

CD = √((-1-1)²+(0-(-4))²) = √20 = 2√5

DA = √((1-(-1))²+(4-0)²) = √20 = 2√5

C) AB = BC = CD = DA = 2√5

Answer:

6

Step-by-step explanation:

Label them as variables

A, B, and C

Now try and list them

ABC

ACB

BAC

BCA

CAB

CBA

There should be 6

The more mathematical way is using factorials

So you would do 3! which is 3*2*1

This also gives you 6

Answer:

  • U'(-14, 8)

Step-by-step explanation:

<u>The transformations include:</u>

  • T<-2,2>·D3

This is a dilation by a scale factor of 3 and then translation 2 units left and 2 units up.

<u>The transformation applied to the point U:</u>

  • U(-4,2) → U'(-4*3 - 2, 2*3 + 2) = U'(-14, 8)
