15-80
Solve it by adding 15 to -80
The final answer is -65
Rearrange your table so that the smallest x comes first (goes on the first line) and the largest last (goes on the last line). Identify the smallest x-value. Here it seems as tho that value is 0. The "initial value" of the function is the y-value corresponding to that "initial value."
In your table, '0' shows up twice as the x-value. Thus, there is more than one y-value associated with the x-value '0.' If that's the case, we must conclude that this table does not represent a function.
8 - 3y = 4y - 13
+3y +3y
8 = 7y - 13
+13 +13
21=7y
y = 3
The formula for the volume of a cone is V =PI x r^2 x h/3
r is given as as 8 and h is given as 63.
V = PI x 8^2 * 63/3
V = PI x 64 x 21
V = PI x 1344
Volume = 1344 PI cu. units.
The answer is D.
