W is in the lower left corner located at (-1,-2)

W' is in the upper left corner located at (-2,1)

Notice that the original Y value (-2) became the new X value (-2) and the original X value (-1) is the inverse of the new Y value (1).

If you look at the coordinates of the other two pints you would see it was the same transformation.

When the X and Y coordinates switch like this, it is a 90 degree clockwise rotation around the origin.

The pie chart shows information about the voters in an election 2800 more women voted than men work out the total number of vote
Cerrena [4.2K]

The angle subtended by the women voters are 100° more than the angle subtended by the men voters.

  • The total number of voters are <u>10080 voters</u>

Reasons:

The angle subtended by the men on the pie chart = 130°

The number of women = 2800 + The number of men

Therefore;

Angle subtended by the women voters on the pie chart = 360° - 130° = 230°

The difference between the angle representing women and the angle

representing men = 230° - 130° = 100°

Therefore;

100° = 2800

Which by common ratios gives;

\dfrac{100^{\circ}}{360^{\circ}} = \dfrac{2800}{Total \ number \  of \ voters }

100 × Total number of voters = 2800 × 360

The \  total \  number  \ of  \ voters = \dfrac{2800 \times 360}{100}  = 10080

The total number of voters = <u>10080</u>

steposvetlana [31]

Answer:

False

Step-by-step explanation:

XY is the diameter of the circle with the centre of this circle being O.

But O on it's own is just a coordinate, and not the circle.
