Answer:
Yes, the distance from the origin to the point (8,√17) is 9 units.
Step-by-step explanation:
The equation of a circle centered at the origin with radius , r has equation:
Since the circle passes through (0,-9), the radius is 9 units because (0,-9) is 9 units from the origin.
We substitute the radius to get:
If (8,√17) lies on this circle, then it must satisfy this equation:
This is True.
This means the distance from (8,√17) is 9 units from the origin.
