Question 28159: A regular octagon with center at the orgin and raidus 4 is graphed in the coordinate plane. since V2 lies on the line y=x, its x- and y-coordinates are equal. Use the distance formula to find the coordinates of V2 to the nearest tenth.

A regular octagon with center at the orgin and raidus 4 is graphed in the coordinate plane. since V2 lies on the line y=x, its x- and y-coordinates are equal. Use the distance formula to find the coordinates of V2 to the nearest teNTH.
DO YOU MEAN REGULAR OCTAGON WAS INSCRIBED IN THE CIRCLE WITH RADIUS OF 4 ..THEN..WE HAVE
DISTANCE FROM CENTRE TO V2 =4
V2 IS ON Y=X....SO ITS X COORDINATE = Y COORDINATE =H SAY
SO 4^2=(H-0)^2+(H-0)^2=H^2+H^2=2H^2=16
H^2=8
H=+SQRT(8)=2.8....0R......-SQRT(8)= -2.8..HENCE V2 IS ..IF IN I QUADRANT THEN
(2.8,2.8)
IF IN III QUADRANT THEN (-2.8,-2.8)
