B because 10p means 10 × p
Answer:
Let the midpoint be M(x,y).
7) x= (3+1)/2= 4/2= 2
y= (-9+5)/2= -4/2= -2
M(2,-2)
8) x= (5-6)/2= -1/2= -0.5
y= (-1-3)/2= -4/2= -2
M(-0.5,-2)
Answer:
45
Step-by-step explanation:
The height of a semisphere is equal a radius of this hemisphere.
But... if we can talk about the height of the hemisphere ;)
R = 0.8m = 80cm then height of hemisphere is equal 0.8m = 80cm.
A. true, P does two complete rotations returning to it's original spot. 720° / 360° = 2
B. false, reflecting across a line will move P.
C. true, moving up 2 then down 2 returns P to it's original position.
D. true, if P is on the line of reflection it remains there.
E. false, P does only 4.5 rotations moving to different coordinates. 1620° / 360° = 4.5
