I need help figuring out the coordinate planes of these points ASAP.

<u>Given</u>:

The vertices of the quadrilateral WXYZ are W(2,4), X(4,2), Y(2,1) and Z(0,2)

The graph is rotated 90° about the origin.

We need to determine the coordinates of the quadrilateral W'X'Y'Z'

<u>Coordinates of the quadrilateral W'X'Y'Z':</u>

The rule to transform the coordinates 90° counter clockwise about the origin is given by

$(x, y) \implies(-y, x)$

Let us substitute the coordinates.

The coordinates of W' is given by

$W(2,4)\implies W'(-4,2)$

The coordinates of X' is given by

$X(4,2) \implies X'(-2,4)$

The coordinates of Y' is given by

$Y(2,1) \implies Y'(-1,2)$

The coordinates of Z' is given by

$Z(0,2) \implies Z'(-2,0)$

Therefore, the coordinates of the vertices W', X', Y' and Z' are (-4,2), (-2,4), (-1,2) and (-2,0) respectively.

If two lines do not intersect , then their intersection is not exactly one point.

Dvinal [7]

If they don't intersect then there is no solution and the lines are parrell.

I need you To reply To This question I need numbers 14-17

The area of a circle is:
$\pi \times r \times r$
"r" being the radius and π being 3.14
14. The diameter is 12. So, to get the radius, we would need to halve it. So, the radius would be 6.
Now we plug in 6 for r and 3.14 for π which makes it
$3.14 \times 6 \times 6$
which equals 113.04
15. The diameter is 9, so to get the radius we need to halve it to get 4.5
Plug in 4.5 for r and 3.14 for π and we get
$3.14 \times 4.5 \times 4.5$
which equals 63.585
16. The diameter is 18, so to get the radius we need to halve it to get 9
Plug in 9 for r and 3.14 for π and we get
$3.14 \times 9 \times 9$
which equals 254.34
17. The diameter is 8, so to get the radius we need to halve it to get 4.
Plug in 4 for r and 3.14 for π and we get
