<u>Given</u>:
The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)
The points are rotated 90° about the origin.
We need to determine the coordinates of the point C'.
<u>Coordinates of the point C':</u>
The general rule to rotate the point 90° about the origin is given by

Substituting the coordinates of the point C in the above formula, we get;

Therefore, the coordinates of the point C' is (-1,2)
Y=cd-8
Add 8 to each side giving you
y+8=cd
Divide by d on each side giving you
C=(y+8)/d
The answer is A. Both collect weather data.
Answer B is false, Balloons generally deconstruct, Satellites do not as they are meant to orbit way past the stratosphere.
Answer C is false, Only satellites can go past the exosphere.
D. Neither of them have any sort of impact on the weather.
It should be 7. No bigger number can go into either.
