[Done] A circle centered at the origin contains the point $(0,-9)$. Does $(8, \sqrt{17})$ also lie on the circle? No, the distance from the center to the point ($8, \sqrt{17}$) is not the same as the radius. No, the radius of 10 units is different from the distance from the center to the point $(8, \sqrt{17})$. Yes, the distance from the origin to the point ($8, \sqrt{17}$) is 9 units. Yes, the distance from the point $(0,-9)$ to the point ($8, \sqrt{17}$) is 9 units.
[Done] Use either the ratio test or the root test as appropriate to determine whether the series [tex]$\sum_{n=1}^{\infty} a_n$[/tex] with given terms [tex]$a_n$[/tex] converges, or state if the test is inconclusive. [tex]$a_n=\frac{n!}{1 \cdot 3 \cdot 5 \cdots(2 n-1)}$[/tex] A. The series converges. B. The series diverges. C. The test is inconclusive.
