1) Points: A, B, C, and D are the vertices of a square in the coordinate plane. Give possible coordinates for A, B, C, and D.
2) How do you know your points form a square without plotting the points?
3) Describe a real-world square that your points could represent.

Find the volume of the described solid. the solid lies between planes perpendicular to the x-axis at x = 0 and x=7. the cross sectionsperpendicular to the x-axis between these planes are squares whose bases run from the parabolay=-31x to the parabola y = 30/x. a) 441b) 147c) 864d) 882
