2. A rectangle ABCD is contained in the unit circle (circle centered at the origin with radius 1). Suppose that we know the following: the point A is the origin, (0, 0). 1 the point B lies on the x-axis with a positive x-coordinate. the point C lies on the unit circle with a postive y-coordinate. Find the point D that maximizes the area of the rectangle.

Dina knows that 3 < 8, and she knows that 1/3 > 1/8. She concludes that it must also follow that 0.3 > 0.8. How do you help her to see what's true?

There are x tons of sand in a pile initially. Then of the sand in the pile is removed from the pile and, after that, another of a ton of sand is dumped onto the pile. Write two equivalent expressions in terms of x for the number of tons of sand that are in the pile now.

Why is y -2/3? How did you get that?
