Find the centroid of the region that is bounded below by the x-axis and above by the ellipse 1. Question 1 What are the coordinates of the centroid? (Simplify your answers. Round to four decimal places as needed.) Match the equation with the graph. Include the directrix that corresponds to the focus at the origin. Label the vertices with appropriate polar coordinates. If the equation is an ellipse, label the center as well. 910 35 + 7 sino Question 2...
