x-y=30
\\ y = 15
\\ x-15 = 30
\\ (x-15)+15 = 30+15
\\ x = 45

Karisha drew pentagon A on a coordinate grid. She then performed a rotation followed by a dilation with scale factor 5 to produc
alex41 [277]

Answer:

A.

Step-by-step explanation:

Rotation is a transformation that turns a figure about a fixed point. An object and its rotation image are the same shape and size, but the figures may be turned in different directions. So, rotation gives us two congruent pentagons.

Dilation is a transformation that produces an image that is the same shape as the original (similar to original), but is a different size. So, dilation gives us two similar pentagons.

A sequence of rotation and dilation produces pentagon that is similar to the initial, but not congruent.

In attached diagram you can see the pictorial representation:

  • pentagon FGHIJ is the rotation image of pentagon ABCDE
  • pentagon KLMNO is dilation image of pentagon FGHIJ

PLEASE HELP ASAP WILL DO BRAINLIEST!!!!!!! Part A: Three equations that all represent the same function f are shown. Select the
Serga [27]

Answer:

  A: f(x)=2x^2 +12x +10

  B: f(0) = 10

Step-by-step explanation:

<u>Part A</u>:

f(0) is a constant in the equation if the form is such that for x=0, all terms are zero except one of them. Standard form is one such form. This is the equation in standard form:

  f(x) = 2x^2 +12x +10

__

<u>Part B</u>:

  f(0) = 0 + 0 + 10

  f(0) = 10

How do you find the radius of a Tetrahedron?
BigorU [14]

Answer:

The center of the tetrahedron divides each of the four heights (or medians) in the ratio 1:3 (in an equilateral triangle the corresponding ratio is 1:2). The smaller part is also the radius of the inscribed sphere. Therefore the radius of this sphere is one quarter of the height or 9 in your case.
