The function f gives the number of copies a book has sold w weeks after it was published. The equation f(w) = 500 * 2^w defines this function. Select all domains for which the average rate of change could be a good measure for the number of books sold.

A. 0 ≤ w ≤ 2
B. 0 ≤ w ≤ 7
C. 5 ≤ w ≤ 7
D. 5 ≤ w ≤ 10
E. 0 ≤ w ≤ 10

12. decide whether each statement is always true, sometimes true, or never true. a. when corresponding points of an original figure and its reflection are connected, the resulting segments are all perpendicular to the line of reflection. b. when a point is reflected over a horizontal line, the y-coordinate of the point stays the same. answer both questions and explain

Drag the tiles to the correct boxes to complete the pairs. match the cart-coordinates with their corresponding pairs of y-coordinates of the unit circle

Is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis.
