Dilation involves changing the size of a figure

The endpoints of the image are (0,3) and (8,3)

The coordinates of the pre-image are give as:

(2,2) and (6,2)

The scale factor is given as:

k = 2

The center of dilation is given as:

(a,b) = (4,1)

The coordinates of the image are then calculated as:

(x,y) = (k(x -a) + a, k(y -b) + b)

For (2,2), we have:

[tex](x,y) \to (2(2 -4) + 4, 2(2 - 1) + 1)[/tex]

[tex](x,y) \to (0, 3)[/tex]

For (6,2), we have:

[tex](x,y) \to (2(6 -4) + 4, 2(2 - 1) + 1)[/tex]

[tex](x,y) \to (8, 3)[/tex]

Hence, the endpoints of the image are (0,3) and (8,3)

Answer:

  b. The variable will always be the letter x (false)

Step-by-step explanation:

Variables can be any letter or symbol. The letter x is often used as a variable, but that is not the only choice. Many formulas, for example, make use of variables that have letters reminding you what they stand for.

For example, the formula ...

  A = 1/2(b1 +b2)h

uses the variables A, b1, b2, and h to represent area, base-1, base-2, and height, respectively. The letter x is not used at all.

Answer:

An example would be... slope intercept form is y=mx+b m being the slope b equal the y-intercept. so an equation would be y=3x+7 3 is the slope and 7 in the y-intercept. I am giving you this way because i do not know what points the graph are going through. And do not know what the graph looks like.

Answer:

6 miles

Step-by-step explanation:
Area is :

[tex]A = \frac{1}{2} hb[/tex]  OR [tex]A = \frac{hb}{2}[/tex]
So base is :
[tex]b = 2 \frac{A}{h}[/tex]
Substituting values given:
b = 2 × (13.5÷4.5)
b = 2×3
b=6

Answer:

the length of the base= 6miles

Step-by-step explanation:

Area of triangle =1/2 *Base*Hight

Now we sub the values in the formula:

13.5 = 1/2 * (length of the base) * 4.5

length of the base = (2 * 13.5)/4.5

length of the base = 6 miles

Answer:

y= -2x+2

Step-by-step explanation:

Slope intercept form is y=mx+b.

To write this equation in slope-intercept form, we must isolate y.

2x+y=2

Subtract 2x from both sides

y= -2x+2

Answer:

(3, - 2 )

Step-by-step explanation:

The total amount need to begin renting the apartment is $2281.

An agreement where a fee is paid for the temporary use of a good, service, or property owned by another is known as renting, sometimes known as hiring, or letting.

We have,

An apartment rents for $665/month.

$95 hookup fee for phone and internet, and $80 TV hookup fee.

So, the total amount

= 665 + 665 + 650 + 126 + 95 + 80

= $2281

Thus, the total amount for rent is $2281.

= C

Step-by-step explanation:

It appears the graph goes through (0,3) and (5,6)

If so, then you have the correct slope and y intercept.

The formula is [tex]C = \frac{3}{5}n+3[/tex] which is the same as writing C = (3/5)n+3

Don't forget about the parenthesis around the 3/5.

We can verify this by plugging in n = 0 and you should get C = 3.

Also, if n = 5 then it leads to C = 6.

Answer:

A = 70

B = 110

C = 110

Step-by-step explanation:

A is opposite of the 70 degree angle, and vertical angles are equal, so it is also 70 degrees.

A straight line is 180 degrees, so 70 + B = 180, making B = 110 degrees.

Both of these rules apply for C, making it also 110 degrees.

Answer:

32 m, 80 m^2

Step-by-step explanation:

Ratio of their sides = 12 : 8 = 3 : 2

Ratio of their perimeter = 3 : 2

so 48 : perimeter of smaller triangle = 3 : 2

Perimeter of smaller triangle = 48 * 2 / 3 = 32 m

Ratio of their areas = 3^2 : 2^2 = 9 : 4

so 180 : area of smaller triangle = 9 : 4

Area of smaller triangle = 180 * 4 / 9 = 80 m^2

Answer:

Total Surface Area: 65.97 cm²

Lateral Surface Area: 37.70 cm²

Step-by-step explanation:

You can solve for the surface area without the height or you can solve for the height and then find the surface are, either way is easy.

Lets first solve without the height. We will solve the surface area with the radius and slant height.

Total Surface area of cone formula: πr (r + s)

Curved surface are formula: πrs

Substitute the values in the picture with the formula

Slant height: 4

Radius: 3

πr (r + s)

π(3)(3 + 4)

(3.141593)(3)(3 + 4)

=9.424778(3 + 4)

=(9.424778)(7)

=65.973446

65.973446 rounded to the nearest hundredth is 65.97
TSA = Total Surface Area

TSA = 65.97 cm²

Now to find the curved surface area or some people call it the Lateral Surface Area

Formula: πrs

Radius: 3

Slant Height: 4

π(3)(4)

(3.141593)(3)(4)

=(9.424778)(4)

=37.699112

37.699112 to the nearest hundredth is 37.70

CSA = Curved Surface Area

CSA = 37.70 cm²

If you choose to compute the height (h) the you have to know both the radius (r) and the slant height (s):

Formula: height (h) = √s² - r²

Slant height = s = 4

Radius = r = 3

Height = h = ?

Now substitute the values into the formula

h = √s² - r²

h = √4² - 3²

h = √16 - 9

h = √7

h = 2.64575131

Height: 2.64575131 cm

Now it's time to find the surface area and curved surface area, now that you have the height:

Surface area formula given height and radius: πr(r + √(r² + h²))

Substitute the values

Height: 2.64575131
Radius: 3

πr(r + √(r² + h²))

π(3)(3 + √(3² + 2.64575131²))

TSA = (3.141593)(3)(3 + √(3² + 2.64575131²)

TSA = 9.424778(3 + √(3² + 2.64575131²)

TSA = 9.424778(3 + √(9 + 7)

TSA = 9.424778(3 + √(16)

TSA = 9.424778(3 + 4)

TSA = 9.424778(7)

TSA = 65.973446

TSA = 65.97

Next, time to find the Curved surface area:

Formula: CSA = πr√(r² + h²)

CSA = πr√(r² + h²)

Substitute the values into the formula

Radius: 3

Height: 2.64575131

Slant Height: 4

CSA  = πr√(r² + h²)

CSA = π(3)√(3² + 2.64575131²)

CSA = 9.424778√(3² + 2.64575131²)

CSA = 9.424778√(9 + 7)

CSA = 9.424778√(16)

CSA = 9.424778(4)

CSA = 37.699112

CSA = 37.70

So, we can conclude that the Total Surface Area is 65.97 and the Lateral Surface Area is 37.70.
