Answer: –16 – 22i Step-by-step explanation: The radius of the circle = 4 + 26i - (-6 + 2i) = 10 + 24i. The radius will be the absolute values of this |10 + 24i|.
If a point is on the circle then it's distance from the centre must be 10+ 24i. -19 + 15i - (-6 + 2i) = -13 - 13i , so this is not on the circle. -16 - 22i - (-6 + 2i) = -10 - 24i = |10 + 24i| , so this is on the circle. 5 + 16i - (-6 + 2i) = 11 + 14i , so this is not on the circle. 20 - 24i - (-6 + 2i) = 26 - 26i. so this is not on the circle.
In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere
