Answer:

Step-by-step explanation:
If Kevin walked his dog 1 2/7 miles and Sam walked his dog 7 times as far, then Sam walked his dog

Together they walked

(0,0)(1,2)......(0,0) is the origin
slope = (2-0) / (1-0) = 2/1 or just 2
y = mx + b
slope(m) = 2
(1,2)...x = 1 and y = 2
now we sub, we r looking for b, the y intercept
2 = 2(1) + b
2 = 2 + b
2 - 2 = b
0 = b
ur equation is : y = 2x + 0...or just y = 2x
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:
-6 is the x-coordinate value
Step-by-step explanation:
Mathematically, slope can be calculated as;
m = (y2-y1)/(x2-x1)
For the value of the slope to be undefined, it means that we are actually dividing by zero
For us to be dividing by zero, it actually means that there is no change in the x-value
The unchanging x-value is what has caused us to have an undefined slope value
Since line k and line g are parallel, their slopes are equal and the slope of k is undefined too
So the x-coordinates of the other points that lie on the line that we used in calculating the slope is -6
