<li><p>The maximum value of y or B is 4, there fore choice A is correct. B dioes not need to be less than A, say point (3,2.5). Plug in for C. f(A) is the y coordinate. Therefore it has to be equal to...
I and III are correct. Choice D</p></li>
<li><p>The diameter of the circle is the width of the rectangle. Thus, radius = 8/2 = 4. Area = pi * r^2... pi * 16 = CHOICE A</p></li>
<li><p>w is proportional to x means that w / x is a constant or x/w is a constant.
Say k. thus, w/x = k
Try 2 values from each table.
A: 3/1 is not = 4/2 --> Wrong
B: 9/3 = 3 not = 16/4 = 4 --> Wrong
C: 10/5 is not = 18/6 --> wrong
D: 21/7 = 3 = 24/8 = 27/9 --> right
E: 10/5 = 2 which is not 15/10... --> Wrong
Thus the answer is D</p></li>
