Answer:
0
Step-by-step explanation:
To find the scaled version of this rectangle by 1/2, start by identifying what this scale factor does to effect the numbers.
In this case, it causes each to divide by two.
Divide each value on the length and width of the rectangle by two.
This results in:
4/2
8/2
Now, perform the division to find your final answer.
This gives you 2 ft by 4 ft.
Answer choice C is the best option.
I hope this helps! :)
32/24
Divide both by 4:
32 / 4 = 8
24 / 4 = 6
8/6
Or you can multiply by 2.
32/24
32 * 2 = 64
24 * 2 = 48
64/48
As a first step, convert to cylindrical coordinates. The equation
is a clue to set
then have
and
. Meanwhile, the plane equation tells you to use
So we parameterize the part of the plane within the cylinder with the vector-valued function
The surface integral giving the area of the surface is
where
denotes the surface in question, and the surface element
is
We have
So the area is
Answer:
= -9 6 × (-9) = -54
