Hi!
To find the semmetry between the nonagon just do this:
360 / 9 = 40
The regular nonagon has rotational symmetry of 40 degrees!
Answer:
8.7 * 10^7
Step-by-step explanation:
Scientific notation is a representation of huge but countable numbers at it's unit place with an expansion of the powers of 10.
Hence,
87,000,000
=87*10^6
=8.7*10^7
All we need to do is apply these points into the function themselves.
For point F, y = -0.25(4) = -1
For point G, y = -0.25(-8) = 0.25(8) = 2
Point F's y-coord is -1 and Point G's y-coord is 2.
