Answer:
B' = (-4, -4)
Step-by-step explanation:
<u>Dilation</u>: A type of transformation that makes the pre-image larger or smaller without changing its shape.
<u>Center of a dilation</u>: a fixed point about which all points are dilated.
Given:
- A = (1, 2)
- B = (-1, -1)
- C = (0, -2)
- Scale factor = 4
For dilation when the <u>center of dilation</u> is the origin (0, 0), simply multiply the coordinates of the vertices of the pre-image by the given scale factor to find the image under dilation:
Therefore:
A' = (1 x 4, 2 x 4) = (4, 8)
B' = (-1 x 4, -1 x 4) = (-4, -4)
C' = (0 x 4, -2 x 4) = (0, -8)
Answer:
7.5
Step-by-step explanation:
<u>To find the median, first order the numbers from least to greatest:</u>
2, 4, 5, 7, 8, 8, 10, 12
<u>Then, find the middle number (number in the middle):</u>
There are 2 middle numbers. 7 and 8.
Because there are 2 numbers, we need to find the average. If there was only one number, that would be the median.
<u>To find the average, add 7 and 8. Then, divide the sum by 2 because there are 2 numbers;</u>
7 + 8 = 15
15 / 2 = 7.5
Have a nice day!
