Answer:
<u><em>750 Books Per Year</em></u>
Step-by-step explanation:
For this problem, we will be using the standard Rate Of Change formula that we use for graphs:
<em>RoC = (y2 - y1) / (x2 - x1)</em>
y = books
x = year
By plugging in the given values:
RoC = (19000 - 16000) / (1999 -1995)
RoC = 3000 / 4
<u>RoC = 750</u>
Represent your unknowns: Let s be the length of one side of the box. The relationship between s and x is s = x-4.
The volume of the box is (length)(width)(height), which here equals the following: V(x) = (x-4)*(x-4)*(x). You may either leave this result as is, or shorten it to V(x) = (x-4)^2*x, or expand (x-4)*(x-4)*(x).
The diameter is 12 cm and the radius is alsays half of the diameter so it will be 6 cm
