Each loop is of a different size, so we can't rotate the figure some angle x to have it line up with itself (0 < x < 360). Therefore, it doesn't have any rotational symmetry. That rules out choice A and choice C. Point symmetry is the same as saying "rotational symmetry of 180 degrees"
The figure doesn't have any line symmetry either. There is no line we can draw and reflect the figure over to have it match up with itself. That rules out choice B and points to choice D
Answer: D) It has no reflectional symmetry.
Just plug -3 where x is into the equation 2x^2 + 6 and solve
f(-3) = 2(-3)^2 + 6
f(-3) = 2(9) + 6
f(-3) = 18 + 6
f(-3) = 24
Answer:
2√61/19
Step-by-step explanation:
sin^2 x = 1 - cos^2 x
= 1 - (3√13/ 19)^2
= 1 - 117/361
= 244/361
sin x = √244/19
= 2√61/19.
3.2n=3.2*5
3.2*5=16 the answer is 16
