Answer:
Step-by-step explanation:
Given
The dimension of the rectangular prism is
The volume of the prism is given by
Therefore, the volume of the prism is .
i believe it is B.
I could be wrong, D is my second choice. but since (left to right) its decreasing, im 89% sure it is B 1/9.
multiply the 3 choices together
3*18*20 = 1080
6x+2+6x<14
add 6x+6x
12x+2<14
subtract 2 from both sides
12x<12
divide by 12
x<1
The two curves intersect when
The region bounded by and the two curves "ends" with a vertex where . So over the interval [0, 2], we have , so that the volume is
That is, each cylindrical shell has a radius of and height , and their contribution to the total volume is times the radius and height.
$11.6
1.45 × 8 = $11.6
That's the Answer
