Mass of 1 sheet = (160 g/m^2)*(1/8 m^2) = 160/8 g = 20 g
mass of 25 sheets = (25 sheets)*(20 g/sheet) = 25*20 g = 500 g
D is the midpoint of A and B
A = (0,s)
B = (r,0)
Add up the x coordinates to get 0+r = r. Then cut that in half to get r/2
Similarly, do the same for the y coordinates: s+0 = s ---> s/2
So the location of point D is (r/2, s/2)
Answer: Choice C
Answer:
1) The graph does represent a function, because it passes the vertical line test.
Step-by-step explanation:
The vertical line test goes over the graph making sure there aren't 2 points together on the same line vertically. Because this passes the vertical line test, meaning there are no points repeating up and down, it is a function.
