Polygon ABCD is dilated by a scale factor of 2 with the center of dilation at the origin to create polygon A′B′C′D′. If the endp
liq [111]

Answer:

A'B' = 34 units

Step-by-step explanation:

Since the dilatation is centred at the origin , then multiply the coordinates by 2

A' = (2(0), 2(- 7) = (0, - 14 )

B' = (2(8), 2(8) = (16, 16)

Calculate the length using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = A'(0, - 14) and (x₂, y₂ ) = B'(16, 16)

d = \sqrt{(16-0)^2+(16+14)^2}

   = \sqrt{16^2+30^2}

   = \sqrt{256+900}

   = \sqrt{1156}

   = 34

For the data below, which of the following are true? Choose all that apply.
masha68 [24]

Answer:

Range 40

Mean 99.4

Step-by-step explanation:

There is a mode since the number 104 shows up twice.

The median is not 100 because it is 102.

The range is 40 because 120 is the largest number and 80 is the smallest number.

So 120 - 80 = 40

The mean is 99.4 because when you add all the numbers up and then divide  it by 10 you get 99.4
