Answer:
Step-by-step explanation:
You use the given information in the standard form of a circle equation to solve for r. We have (h, k) which is the center and a point (x, y). The standard equation for a circle is
Filling in:
and
and
Now that we used the coordinate we don't need it anymore. x and y go back into the equation as x and y, not numbers. We do, however, need the center. Writing the equation:
which is choice D.
Answer:
- 15 2/9
Step-by-step explanation:
3⁻² = 1 / 3² = 1/9
(½)⁻⁴ = 1 / (½)⁴ = 1 / (1/16) = 16
³√(8/27) = ³√8 / ³√27 = 2/3
1/9 - 16 + 2/3 = 1/9 - 144/9 + 6/9 = - 137/9 = - 15 2/9
