To check for symmetry on the x axis, replace y with –y
-y^2 –x(-y) =2
<span> Apply the product
rule, since the equation is not identical tot eh original equation it is not
symmetric about the x axis</span>
<span> Now do the same for y
axis by replacing x with –x</span>
<span> Again using product
rule the equations are not identical, so it is not symmetric about the y axis</span>
<span> To check the origin,</span>
<span> Replace both x &
y with –x & -y</span>
Again using product rule, the equations are not identical so
it is not symmetric about the origin

Answer:
x ≈ 12.9
Step-by-step explanation:
In relation to the angle in this right triangle, the sides marked are the adjacent side and the hypotenuse. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(72°) = 4/x
Multiplying by x/cos(72°), we have ...
x = 4/cos(72°)
x ≈ 12.9
Answer:
Step-by-step explanation:
Notice that KL = LM and PQ = QR since OL and OQ are perpendicular to both KM and PR.
It follows that QR = (1/2) PR = 20 cm. We also know that MR = 21.
Now in order to solve the problem we just need OQ=OL
Therefore the perimeter of the pentagon is
