Answer:
The answer is 2.5ft².
Step-by-step explanation:
Given that the area of trapezoid formula is A = 1/2×(a+b)×h where a and b is the length and h is the height. Then substitute the following values into the formula :
Let a = 1.2,
Let b = 0.8,
Let c = 2.5,
Answer:
Step-by-step explanation:
2x - 5
2(3) - 5
2 times 3 = 6
6-5=1
B) is the answer
Answer:
Functions: Second Graph
Step-by-step explanation:
The other two are not. Use the vertical line test. I'm pretty sure but not 100%
Decompose the surface into three components,
, corresponding respectively to the cylindrical region and the top and bottom disks:
where
and
,
where
and
, and
where
and
.
For the cylinder, we have
and the integral over this surface is
Bottom disk:
and the integral over the bottom disk is
The setup for the integral along the top disk is similar to that for the bottom disk, except that
:
Finally, the value of the integral over the entire surface is the sum of the integrals over the component surfaces:
Answer:
-16 and 16
