I'm pretty sure it's 22%
If it's not, then I'm sorry!!
Answer:
10.00022
10.0011
Step-by-step explanation:
2.14 and 4.673
2.14 x 4.673 = 10.00022
2.55 and 3.922
2.55 x 3.922 = 10.0011
Answer:
![x^2+(y+1)^2=2](https://tex.z-dn.net/?f=x%5E2%2B%28y%2B1%29%5E2%3D2)
Step-by-step explanation:
We use the formula for a circle with center at (0, -1), that goes through the (x, y) point (-1, -2):
![(x-0)^2 + (y-(-1))^2 = R^2\\Using \,\,\,point\,\,\,(-1, -2)\\(-1-0)^2+ (-2+1)^2 = 1 + 1 = 2 = R^2](https://tex.z-dn.net/?f=%28x-0%29%5E2%20%2B%20%28y-%28-1%29%29%5E2%20%3D%20R%5E2%5C%5CUsing%20%5C%2C%5C%2C%5C%2Cpoint%5C%2C%5C%2C%5C%2C%28-1%2C%20-2%29%5C%5C%28-1-0%29%5E2%2B%20%28-2%2B1%29%5E2%20%3D%201%20%2B%201%20%3D%202%20%3D%20R%5E2)
Therefore, the equation of this circle can be written as:
![x^2+(y+1)^2=2](https://tex.z-dn.net/?f=x%5E2%2B%28y%2B1%29%5E2%3D2)
The first step is to locate the coordinates of the vertices of the arrow. From the graph,
A = (2, 1)
B = (2, 3)
C = (1, 3)
D = (3, 5)
E = (5, 3)
F = (4, 3)
G = (4, 1)
If (a, b) is reflected on the line y = - x, the coordinates of the image is (- b, - a)
By applying this rule, the new coordinates after reflecting the arrow over the line y = - x are
A'(- 1, - 2)
B'(- 3, - 2)
C'(- 3, - 1)
D'(- 5, - 3)
E'(- 3, - 5)
F'(- 3, - 4)
G(- 1, - 4)
