If (9, 1) and (1, 9) are the endpoints of a diameter of a circle, what is the equation of the circle?

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

Because of mourning president bush's death

Ithink if ur looking for a ratio it would be 12: 3
