Curl is defined as:
Which can be rewritten as:
This is because C1 lies on the xy plane and thus it's unit vector will be .
By similar arguments the rest will follow too.
Now, area of each circle will be:
Therefore, Curl, as per our definition will be:
Thus, Curl=
Which is the required answer.
Answer:
Area/length=width
96/8=12
the width would be 12
You reverse the equation so it would be width x length =area but you are missing the width so you reverse the equation and divide instead to find missing sides
Step-by-step explanation:
X + y = 17
x - y = 29
x = 17 - y
x - y = 29
x = 17 - y
17 - y - y = 29
x = 17 - y
17 - 2y = 29
x = 17 - y
- 2y = 29 - 17
x = 17 - y
-2y = 12
x = 17 - y
y = -6
x = 17 - (-6)
y = -6
x = 17 + 6
y = -6
x = 23
y = -6
Answer:
(x + 2)^2 + (y - 5)^2 = 32 or [4√2]^2
Step-by-step explanation:
Here we have a circle with center at (-2, 5), which represents (h, k). Thus, the standard equation of a circle with center at (h, k), shown below
(x - h)^2 + (y - k)^2 = r^2 (where r represents the radius of the circle)
becomes:
(x + 2)^2 + (y - 5)^2 = r^2. We know that this circle passes through (-6, 1), so this last equation becomes:
(-6 + 2)^2 + (1 - 5)^2 = r^2, or 16 + 16 = r^2.
Then 2(16) = r^2.
Taking the square root of both sides yields r = 4√2.
The desired equation of this circle is then
(x + 2)^2 + (y - 5)^2 = 32 or [4√2]^2
