Arandom triangle is formed in some way, such that all pairs of angles have the same joint distribution. what is the correlation between two of the angles (assuming that the variance of the angles is nonzero)?

The parabola opens: y=√x-4 (principal square root) up down right left

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.

Find the area of the triangle formed by the origin and the points of intersection of parabolas y=−3x^2+20 and y=x^2−16.
