The mirror is in a shape of a pentagon
Answer:
a and c I'm 99percent shure
Y-axis symmetry=(r, theta)=(-r,theta)
-5-5cos(theta)=r
-r=5+5cos(theta)
no y-axis symmetry
x-axis symmetry=(r,theta)=(r,-theta)
cosine is an even function, so yes it is symmetric around x-axis
origin symmetry=(r,theta)=(-r,theta) or (r, theta+pi)
no, as there is no y-axis symmetry
See picture for reply and solution steps.
C =7
d is 6 times c+3
d=6c+3
d=6d+3 is equation
(if you sub, you would get 45 is weight)
