Пжжж помогите

Step-by-step explanation:

1) до одиниць: 2,73 (3); 3,052 (3); 7,5789 (8);

2) до десятих: 11,82 (11,8); 0,4859 (0,5); 11,2342 (11,2):

3) до сотих: 0,451 (0,45); 12,499 (12,50); 1,574 (1,57).

i believe the answer is the polygon, heptagon.

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
