Answer:

5.66

Step-by-step explanation:

Given data

the coordinates are

f=(-8,5) and

x1= -8

y1= 5

k=(-4,1)

x2= -4

y2= 1

The distance can be expressed using the formula

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-4+8)²+(1-5)²)

d=√((4)²+(-4)²)

d=√16+16)

d=√32

d=√32

d=5.656

Hence the distance between the points is 5.66

Answer:

(0,-1), (1,0), (2,3)

Step-by-step explanation:

The input values are your x values.

The output values are your y values.

So, we are going to plug in x to get y.

1. Let's plug in 0 for x.

[tex]y=0^{2} -1[/tex]

[tex]y=0-1[/tex]

[tex]y=-1[/tex]

Our first point is located at (0,-1)

2. Let's plug in 1 for x.

[tex]y=1^{2} -1[/tex]

[tex]y=1-1[/tex]

[tex]y=0[/tex]

Our second point is located at (1,0)

3. Let's plug in 2 for x.

[tex]y=2^{2} -1[/tex]

[tex]y=4-1[/tex]

[tex]y=3[/tex]

Our third point is located at (2,3)

All done! Hope you got a better example from my explanation!

Answer:

It’s A

Step-by-step explanation:

If it is dilated by a  scale factor of 1/3 with the center of dilation at the origin, The new point is at J'(-1, 2), K'(2, 2), L'(1, 1) and M'(0, 1).

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point A(x, y) is dilated by a scale factor of k, the new point is at A'(kx, ky).

JKLM has vertices at J(-3, 6), K(6, 6), L(3, 3) and M(0, 3). If it is dilated by a  scale factor of 1/3 with the center of dilation at the origin, The new point is at J'(-1, 2), K'(2, 2), L'(1, 1) and M'(0, 1).

B. 2764 + x Greater-than-or-equal-to 5000

Step-by-step explanation:

A. 2764 + x > 5000

B. 2764 + x Greater-than-or-equal-to 5000

C. 2764 + x Less-than-or-equal-to 5000

D. 5000 + x > 2764

Current balance of their account = $2,764

They need a balance of at least $5,000

At least in inequality means greater than or equal to

Let x = remaining balance to make at least $5,000

The inequality is

2764 + x greater than or equal to 5,000

The answer is B. 2764 + x Greater-than-or-equal-to 5000

The inequality that can be used to determine the amount of money she still needs to save is x ≥ $5000 - $2,764.

The following are inequality signs and what they mean:

The inequality sign to be used is ≥.

Step-by-step explanation:

Area of Circle= 3.14(pi) x r^2

Area=615.44

Sector Area = 315/360 x 615.44 = 538

Answer:

6,4

Step-by-step explanation:

Create a system of equations

l-2=w

w*l=24

Substitute

l-2*1=24

l=6

6-2=4

w=4

Dimensions of the rectangle are 6inch and 4 inch.

"Rectangle is a quadrilateral whose all  angles are right angle and opposite sides are parallel and equal in measurement."

" Dimension is measurement of any object such as length, width and height of any object."

"Area is a space occupied by an object."

Let 'l' be the length of the rectangle.

According to the question,

Width = l - 2

Area= 24 square inches

Formula used

Area of a rectangle = length x width

[tex]24 = l[/tex] × [tex](l-2)[/tex]

⇒[tex]24[/tex] = [tex]l^{2} -2l[/tex]

⇒ [tex]l^{2} -2l -24=0[/tex]

⇒[tex]l^{2} -6l+4l -24 =0[/tex]

⇒[tex]l(l-6) +4(l-6) =0[/tex]

⇒[tex](l-6)(l+4) =0[/tex]

⇒[tex]l=6[/tex] or [tex]l= -4[/tex]

length cannot be negative.

Therefore, [tex]l=6[/tex]inch

⇒width = [tex]6-2[/tex]

⇒ width = 4 inch

Hence the dimensions of the rectangle are 6inch and 4 inch.
