By applying the equation of dilation, the coordinates of the vertices of the triangle ABC are A'(x, y) = (-12, 0), B'(x, y) = (0, -9) and C'(x, y) = (-12, -9).

<h3>How to find the image of a triangle</h3>

A dilation is a type of <em>rigid</em> transformation. <em>Rigid</em> transformations are transformations applied to <em>geometric</em> loci such that <em>Euclidean</em> distances are conserved.

There is a triangle and its image must be a triangle, the <em>new</em> triangle is found by transforming the three vertices of the prior one following this formula:

A'(x, y) = P(x, y) + k · [A(x, y) - P(x, y)]     (1)

Where:

  • P(x, y) - Center of reflection.
  • A(x, y) - Original vertex
  • A'(x, y) - New vertex
  • k - Dilation factor

If we know that P(x, y) = (0, 0), A(x, y) = (-4, 0), B(x, y) = (0, -3) and C(x, y) = (-4, -3), then the new vertices of the triangle are, respectively:

Point A

A'(x, y) = (0, 0) + 3 · [(-4, 0) - (0, 0)]

A'(x, y) = (-12, 0)

Point B

B'(x, y) = (0, 0) + 3 · [(0, -3) - (0, 0)]

B'(x, y) = (0, -9)

Point C

C'(x, y) = (0, 0) + 3 · [(-4, -3) - (0, 0)]

C'(x, y) = (-12, -9)

Lastly, we draw the two triangles, which are presented in the image attached below.

hram777 [196]

Answer:

The surface area of the red sphere is 452.4 cm²

Step-by-step explanation:

The question here is easy to calculate provided you understand it and apply the formula necessary for deriving the answer and it says that two spheres are similar. The surface area of the blue sphere is 9160.9 square centimeters with a radius of 27cm. What is the surface area of the red sphere with a radius of 6cm

Surface area of a sphere is given as 4 × pi × r²

And if we have he radius as 6 cm,we can then input the figured so as to get the surface area of this sphere.

Remember that pi= 22/7 or 3.142

4 × 22/7 × 6² = 452.4 cm²

on a road trip, the Morgan family traveled 408 miles in 6 hours, how many miles did the family travel in 4 1/2 hours?
Radda [10]

Find miles per hour by dividing total miles by total time:

408 / 6 = 68 miles per hour

Now multiply miles per hour by time:

68 x 4 1/2 = 306 miles

Answer: 306 miles

First I made equations for the perimeter (p) in terms of the width (w) and same for the length (l).

Then, since all the sides added together equaled the perimeter, I made the perimeter equation equal to all the sides added together, all in terms of width (no other variables than w).

Solving that algebraically, you can find w. And then plug that back into the equation for length to find length.

w=8, l=11

The length of a rectangle is I m more than twice the width, and the area of the rectangle is 28 m. Find the dimensions of the re
Oksanka [162]

Answer:

width = 3.5 feet        length = 8 feet.

Step-by-step explanation:

 W=x

L=2x+1

Area=(2x+1)x=28

2x^2+x=28

2x^2+x-28=0

 (2x-7)(x+4)=0

x=3.5,-4.  It should be a positive number so W=3.5

2x+1=8          2x3.5=7     7+1 = 8    L=8

That area is 28 ft^2

width is 3.5 feet and length is 8 feet.
