Im no expert but i think its
input: x,independent variable ,domain
output: y, dependent variable , range
extra: f(x) , discrete, and slope
Once again the answer is 0. The reason is because the cube is 3 by 3 there is a cube 1 by 1 in the center of the big cube, because it is surrounded by other 1 by 1 cubes that cube doesn't get any sides painted. Therefor there is no possibility for all cubes to have at least one side painted.
The answer is 240 because 11 x 8 is 88 but you divide by 2 since it's a triangle so you get 44 and since there's 4 triangles you do 44 x 4 and get 176 then 8 x 8 is 64 plus 176 is 240
This means that if b doubles, then a will become half as large. For the inverse of the ratio 2 to 1 ("doubles") is the ratio 1 to 2 ("half"). The terms are exchanged; the inverse of the ratio a : b is the ratio b : a.
When a varies inversely as b, we say that a is inversely proportional to b.
