Polygon ABCD with A (2,4), B (-4,-8), C (0,4), and D (12,-2), is dilated are the new coordinates? Is this a reduction or enlarge
Paraphin [41]

For this exercise it is important to know that, in Dilations:

1. When the scale factor is greater than 1, the Image (the figure obtained after the transformation) is an enlargement.

2. When the scale factor is greater than 0 but less than 1, the Image is a reduction:

0You know that the coordinates of the vertices of the polygon ABCD are:[tex]\begin{gathered} A(2,4) \\ B(-4,-8) \\ C(0,4) \\ D(12,-2) \end{gathered}

And the scale factor is:

k=\frac{1}{2}

Since:

0

It is a reduction.

You can identify that the rule of this transformation is:

undefined

Solve the triangle: b=200, c=250, A=75 degrees.
ValentinkaMS [17]

Answer:

  see below

Step-by-step explanation:

You can use the law of sines to choose the correct answer:

  b/c = sin(B)/sin(C) ≈ 0.8

For the first answer choice,

  sin(44.3)/sin(60.7) ≈ 0.8009 . . . . . . as close as you expect to get

____

The second answer choice has the wrong ratio of sines.

The third answer choice has B > C, which it cannot be since b < c.

_____

The law of cosines can be used to find "a":

  a^2 = b^2 + c^2 -2bc·cos(A) = 102500-100000cos(75°) ≈ 76,618

  a ≈ √76618 ≈ 276.8 . . . . . . matches the first answer choice

1m as a percentage of 56mm
andreev551 [17]

Answer:

1785.71429% or ~1785.71%

Step-by-step explanation:

to find this answer you must divide 56 mm by 1 m

1 m is also 1000 mm

so

1000 / 56 is what you need to do

1000/56 = 17.8571429

your percentage is essentially 1785.71429%
