Polygon ABCD with vertices at A(−4, 6), B(−2, 2), C(4, −2), and D(4, 4) is dilated using a scale factor of one eighth to create polygon A′B′C′D′. If the dilation is centered at the origin, determine the vertices of polygon A′B′C′D′.
Answers
Answer:
The third option
Step-by-step explanation:
Multiply all coordinates by 1/8 or 0.125
So
A(−4, 6) → A(-0.5, 0.75) when both points are multiplied by 0.125
B(−2, 2) → B(-0.25,0.25) when both points are multiplied by 0.125
We could go on and find all the values but the third option is the only one that has the right values so it has to be correct
Vertex A′: (x', y') = (kx, ky) = (1/8) * (-4,6) = (-1/2, 3/4)
Therefore, the coordinates of A′ are (-1/2, 3/4)
Vertex B′: (x', y') = (kx, ky) = (1/8) * (-2,2) = (-1/4, 1/4)
Therefore, the coordinates of B′ are (-1/4, 1/4)
Vertex C′: (x', y') = (kx, ky) = (1/8) * (4,-2) = (1/2, -1/4)
Therefore, the coordinates of C′ are (1/2, -1/4)
Vertex D′: (x', y') = (kx, ky) = (1/8) * (4,4) = (1/2, 1/2)
Therefore, the coordinates of D′ are (1/2, 1/2)
So, the vertices of dilated polygon A′B′C′D′ are (-1/2, 3/4), (-1/4, 1/4), (1/2, -1/4), and (1/2, 1/2).

Answers
Answer:
17/157=10.82%
Step-by-step explanation:
Answer: 10.8% (maybe 11% depending on if your teacher wants a decimal in the answer or not)
Step-by-step explanation:
157 x 0.108 = 16.956

HOPE THIS HELPS!
Now if you were to double the dimensions, the new length would be 4, width would be 6, and the height would be 8. You would also do 2( W•L + H•L + H•W) which in this case is 2( 6•4 + 8•4 + 8•6) which is 208. Therefore, the surface area is 4 times greater.

Answer:
width: 2 : 15volume: 8 : 3375surface area: 4 : 225Step-by-step explanation:
Given a model has a scale factor of 2:15 with respect to the original car, you want to know the ratios of model : original for width, volume, and surface area.
RatiosThe scale factor is the ratio of linear dimensions, such as width. This means the ratio of widths will be 2:15, the same as the scale factor.
Areas have units of the square of a linear dimension. Hence the ratio of areas is the square of the ratio of linear dimensions, the square of the scale factor. The ratio of surface areas will be 2²:15² = 4:225.
Volumes have units of the cube of a linear dimension. Hence the ratio of volumes is the cube of the ratio of linear dimensions, the cube of the scale factor. The ratio of volumes will be 2³:15³ = 8:3375.
The model : original ratios are ...
width: 2 : 15volume: 8 : 3375surface area: 4 : 225<95141404393>

there must be at least 2 boxes of fudge containing nuts at the fudge shop on Monday morning.The scenario states that the total amount of fudge containing nuts on Monday afternoon is at least 29(5/8) pounds. So, we can write the inequality:x + 12(3/4) ≥ 29(5/8)
How to solve the question?
(a) Let's define "x" as the amount of fudge containing nuts that was at the fudge shop on Monday morning. Since three-fourths of the fudge contains nuts, we can say that:
x = (3/4)total fudge at the fudge shop on Monday morning
Then, Helena prepares an additional 12(3/4) pounds of fudge containing nuts. Therefore, the total amount of fudge containing nuts on Monday afternoon is:
x + 12(3/4)
The scenario states that the total amount of fudge containing nuts on Monday afternoon is at least 29(5/8) pounds. So, we can write the inequality:
x + 12(3/4) ≥ 29(5/8)
(b) Let's first convert the mixed number 12(3/4) into an improper fraction:
12(3/4) = (4*12 + 3)/4 = 51/4
Similarly, we can convert the mixed number 29(5/8) into an improper fraction:
29(5/8) = (8*29 + 5)/8 = 233/8
Now, we can substitute these values into the inequality we wrote in part (a):
x + 51/4 ≥ 233/8
To solve for x, we need to isolate it on one side of the inequality. Let's start by subtracting 51/4 from both sides:
x ≥ 233/8 - 51/4
x ≥ 10/8
Simplifying the right-hand side:
x ≥ 5/4
Therefore, the inequality that represents the scenario is:
(3/4)total fudge at the fudge shop on Monday morning + 12(3/4) ≥ 29(5/8)
And the solution to this inequality is:
x ≥ 5/4
(c) Since fudge is packaged into 1-pound boxes, the fewest number of boxes of fudge at the fudge shop on Monday morning is equal to the amount of fudge containing nuts on Monday morning, which is "x". From part (b), we know that:
x ≥ 5/4
The smallest whole number that is greater than or equal to 5/4 is 2. Therefore, there must be at least 2 boxes of fudge containing nuts at the fudge shop on Monday morning.

the equations: 2+x=-12 and -12+x=2 I need to know which one goes with which.
Answers
Answer:
The equation: 2+x=-12 goes to D
The equation -12+x=2 goes to C
Step-by-step explanation:
2+x=-12 goes to D because they said that the temperature fell to -12 degrees, meaning the end temperature was -12, so -12 has to be isolated on one side of the equal sign.
-12+x=2 goes to C because they said that the temperature rose to 2 degrees, meaning the end temperature was 2, so 2 has to be isolated on one side of the equal sign, making this the correct format.
