Answer:
1246 yards
Step-by-step explanation:
To find the yard of fencing she needs for he cows, we simply need to find the perimeter of the rectangular area.
The area is 200 yards by 423 yards.
The perimeter is the sum of all the sides of a rectangle and it is given by:
P = 2(L + B)
P = 2(200 + 423) = 2(623)
P = 1246 yards.
She needs 1246 yards of fencing.
The slope of each line segment of ΔQRS are-
- QR = 3/10
- RS = - 10/3
- QS = -7/13
<h3>What is meant by the slope of the line?</h3>
- A slope of a line is defined in mathematics as the change in y coordinate to regard to the shift in x coordinate.
- The net change in y-coordinate is denoted by Δy, whereas the net change in x-coordinate is denoted by Δx.
For the given question,
The coordinates of each vertices of the triangle are-
Q = (-7, -2)
R = (3, 1)
S = (6, -9)
The formula for the slope of the line segment.
Slope = m = (y2 - y1)/(x2 - x1)
Slope QR = (1 + 2)/(3 + 7)
Slope QR = 3/10
Slope RS = (-9 - 1)/(6 - 3)
Slope RS = - 10/3
Slope QS = (-9 + 2)/(6 + 7)
Slope QS = -7/13
Thus, the slope of the each line segment of the given triangle QRS is found.

Answer:
The value of q are 0.781,-1.281.
Step-by-step explanation:
Given : Two vectors
and
are perpendicular to each other.
To find : The value of q ?
Solution :
When two vectors are perpendicular to each other then their dot product is zero.
i.e. 
Two vectors
and





Using quadratic formula,




Therefore, The value of q are 0.781,-1.281.
