Answer:
B
Step-by-step explanation:
Plot the graph of the equation 
on the polar coordinate plane (see attached diagram for details).
A. There is no symmetry about the horizontal axis, because three parts of the graph are above the axis and two parts of the graph are under the axis.
B. There is symmetry about the vertical axis, because if you reflect left (or right) part about the vertical axis it will coincide with the other part.
C. There is no symmetry about the pole (see diagram)
D. This option is false, because option B is true (there is axis of symmetry)
Answer:
Since the shape was formerly a square,ofarea 100in²
Then,Area of square=side×side
100in²=side²
side=√100in²
side=10 inches
Perimeter of the shape=10+10+7+6+5
=38inches
Now a length of 3inches is cut off from the upper horizontal side and a length of 4in is also cut off from the right vertical side.
So now we can say a triangle of base 4in and height 3in is cut off from the square.
Area of cut off triangle=½base×height
=½×4×3=0.5×12
=6 inches ²
So the Area of the shape=Area of square-Area of triangle
=100-6=94inches²

Answer:
B
Step-by-step explanation
a squared plus b squared equals c squared.
16 plus 144 equal 160.
now square 160
