A circle can be rotated to make a sphere
Answer:
D = 0 , Dx = 4 , Dy = -6 , Dz = 2
Step-by-step explanation:
As per<u> cramer's rule</u>,
D = | 7 6 4 | = 0
| 3 3 3 |
| 4 4 4 |
Dx = | 10 6 4 | = 4
| 1 3 3 |
| 2 4 4 |
Dy = | 7 10 4 | = -6
| 3 1 3 |
| 4 2 4 |
Dz = | 7 6 10 | = 2
| 3 3 1 |
| 4 4 2 |

Answer:
25/64
Step-by-step explanation:
X² + y² - 6x + 16y - 152 = 0
x² - 6x + y² + 16y - 152 = 0
x² - 6x + y² + 6y = 152
(x² - 6x + 9) + (y² + 6y + 9) = 152 + 9 + 9
<u>(x - 3)²</u> + <u>(y + 3)²</u> = <u>170</u>
170 170 170
(x - 3)²/170 + (y + 3)²/170 = 1
