Sketch the region bounded by the curves, and visually estimate the location of the centroid. (Do this on paper. Your instructor may ask you to turn in this work.) Then find the exact coordinates of the centroid. y = 9 − x^2 y = 0x, y= ?

The sum of two numbers is 86, and their difference is 20. find the two numbers

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

This is about circle theorems. someone asap : (
