We know that
if P is the centroid of triangle ABC
so
PD=(1/3)*BD
BD=3*PD-----> BD=3*3-----> BD=9 units
the answer is
BD=9 units
In general, in polar coordinates (r, ω) = (-r, ω+π), because when you add π radians to an angle you are turning 180 degrees and then need to change the sign of the radius to preserve the original point.
Then (-5, π/4) = (5 , π/4 + π) = (5, 5π/4)
Answer: (5, 5π/4)
Mean = (5+6+4+6+4)/5 = 25/5 = 5
answer
mean = 5
The slope is -1/4 and the y-intercept is 1.
Hope this Helps!!
