## anonymous one year ago A circle is centered at the origin and contains the point (-6, 0.)  Use complete sentences and proper grammar to give a justification as to whether or not the point (4, 4.5) lies on the circle.  Show any calculations used.

well we know it is 6 units away from the origin in every direction so |dw:1437577938419:dw| kinda like this

3. anonymous

okay

4. anonymous

$\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$ that is the distance formula so plug in 0,0 and 4,4.5

5. anonymous

okay

6. anonymous

ill do it too

7. anonymous

what did u get

8. anonymous

17.5

9. anonymous

r u sure

10. anonymous

x2=4 and x1=0 y2=4.5 y1=0

11. anonymous

@Aliypop plug those in

12. anonymous

10.55

13. anonymous

I mean 10.5

14. anonymous

its actually 6.02

15. anonymous

okay

16. anonymous

which is greater than 6

17. anonymous

so no then u just show the work from the equation

18. anonymous

okay

19. anonymous

so is it a circle or no?

20. anonymous

it is not in the circle unless it says to round

21. anonymous

okay
