PLEASE HELP!!!!! Under a dilation centered at the origin, the vertex, (3, −5), of a polygon is moved to the point (−15, 25) .

What is the scale factor of the dilation?

Enter your answer in simplified form in the box.

The solutions to the questions are

The figure represents the given parameter.

On the figure, we have the following shapes:

The area is calculated as

Area = Area of rectangle 1 + Area of rectangle 2

So, we have

Area = 7 * 5 + 3 * 10

Evaluate

Area = 65

Hence, the area of the floor is 65 square feet

On the figure, we have the following shapes:

The perimeter is calculated as

Perimeter = Perimeter of rectangle 1 + Perimeter of rectangle 2

So, we have

Perimeter = 2 *(7 + 5) + 2 * (3 + 10)

Evaluate

Perimeter = 50

Hence, the perimeter of the floor is 50 feet

The total cost is calculated as

Total Cost = Cost of baseball * Area of baseball + Cost of tile * Area of tile

So, we have

Total Cost = 2 * 7 * 5 + 2.5 * 3 * 10

Evaluate

Total Cost = 145

Hence, the total cost to buy tile and baseboards for your bathroom is $145

Based on the amount the winner receives, the interest rate to be compounded annually, and the number of years, the amount that should be invested to award the price is $35,720.80.

The amount that should be invested is the present value of the $8,000 for the next 5 years. This amount would be the present value of an annuity due because constant payments that come at the beginning of a period are annuity dues.

Present value of annuity due = Annuity due x (Present value interest factor of annuity due, 6%, 5 years)

Solving for the amount to be invested to award the price gives:

= 8,000 x 4.4651

For every 21 liters of petrol a car can run for 80 km- 58.2 liters of petrol would be required to ensure the car has enough petrol of a trip that is 224 km unitary method

It is provided that to run 80km car requires 21 liters of petrol

To know how much petrol is required for a trip of 224 km, we first would require to know how much petrol is required to run 1 km

This is called unitary method

Petrol required by car to run 1 km would be petrol required by car to cover 80kms of distance divided by 80 km of distance = 21 liters of petrol/ 80 km distance

                                                      = 21/80

                                                      =0.26 liters

So, petrol required by car for a trip of 224 km= 0.26 liters  ×224km

                                                                          = 0.26× 224

Graph of g is a translation where g(x) = (x+2)^2 - 2x – 1

f(x) = x^2 - 2x

g(x) = f(x+2) + 3

Translation is a movement of the graph either horizontally parallel to the x-axis or vertically parallel to the y-axis. A translation is a geometric transformation that moves every point of a figure, shape or space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system. In a Euclidean space, any translation is an isometry.

Hence , g(x) = (x+2)^2 -2(x+2) + 3 = (x+2)^2 - 2x - 1. When we graph the equations, we can confirm that our answer is correct.

We may infer from the number line that A and B are separated by 8 units (AB).

Let AB stand for the separation between points A and B, and let AC stand for the separation between points A and C. Let B stand for the separation between points B and C. Hence:

Point B being halfway between A and C, we can infer:

AB + BC Equals AC (Postulated segment addition)

As a result, since the distance between points A and B is equal to 1/3 of AC:

AC/3 = AB = 1/3(AC)

But as shown in the accompanying image:

AC equals 16 – (–8) to 24 units.

Step-by-step explanation:

Define the variable

Let x be the unknown number.

Therefore:

[tex]\begin{aligned}& \textsf{Four times a number}: \quad & 4x\\& \textsf{Twenty less than four times a number}: \quad & 4x-20\\& \textsf{Twenty less than four times a number is twenty one}: \quad & 4x-20=21\end{aligned}[/tex]

To find the number, solve the found equation for x:

[tex]\begin{aligned}\implies 4x-20&=21\\4x-20+20&=21+20\\4x&=41\\\dfrac{4x}{4}&=\dfrac{41}{4}\\x&=10.25\end{aligned}[/tex]

Therefore, the unknown number is 10.25.

As an improper fraction, this is ⁴¹/₄.

As a mixed number, this is 10 ¹/₄.

Answer:

x = 10.25

Step-by-step explanation:

Given that,

→ Twenty less than four times a number is twenty one.

The equation we form,

→ 4x - 20 = 21

Now the value of x will be,

→ 4x - 20 = 21

Step-by-step explanation:

Use the formula

where P is amount deposited, A the accrued amount, n number of years and r the interest rate in % compounded annually

The division by 100 is necessary to convert r% to a decimal for calculations

We have P = 850, r = 7% and n = 3

Plugging these in we get
[tex]A = 850\cdot (1 + (\dfrac{7}{100})^3\\\\A= 850\cdot(1 + 0.07)^3\\A = 850\cdot1.07^3\\\A = \$1,041.29[/tex]

Step-by-step explanation:

You want to know the image of the point (-4, -6) after reflection in the x-axis and translation 3 left and 1 down.

The composition ...

  [tex]T_{-3,-1}\circ r_{\text{x-axis}}[/tex]

is interpreted to mean reflection in the x-axis occurs first, then translation by (-3, -1).

That is, a composition of transformations is evaluated right to left.

Reflection in the x-axis moves a point from below the x-axis to the same distance above the x-axis. That is, the sign of the y-coordinate changes:

  (-4, -6) ⇒ (-4, 6) . . . reflection in the x-axis

The translation vector is added to the coordinates of the point:

  (-4, 6) +(-3, -1) = (-4-3, 6-1) = (-7, 5)

The image of the point is located at (-7, 5).
