Find the center and radius of the circle represented by the equation below. \[ (x-10)^{2}+(y-9)^{2}=256 \] Answer Attempt 1 out of 5 Center: Radius:

Which of the following describes supplementary angles? A. Angles that areadjacent. B. Two or more angles whose sum equals 360 degrees. C. Two angles whose sumequals 180 degrees. D. Angles whose measurements equal 90 degrees.

Analyze the equation. That is, find the center, vertices, and foci of the ellipse and graph it. \[ \frac{x^{2}}{49}+\frac{y^{2}}{4}=1 \]
