<span>The derivative of a function at a point gives the slope of the line tangent to the function's graph at that point.
</span>Therefore,
gives the slope of the tangent line to the graph of
where
, which is the point
.
We know this line passes through
, and we are also given that it passes through
. <span>This should be enough to find the slope of that line.

Step-by-step explanation:
The slope of a line is Change in y
--------------------
change in x
y does not change

Slope = 0
Horizontal lines have 0 slope
Vertical lines have undefined slope
W= width L= length = 2W
Area of Rectangle= Length * Widthsubstitute the area and the value of L in the formula
28,800 m^2= 2W * W
28,800= 2W^2divide both sides by 2 in an effort to isolate the variable w
14,400= W^2take the square root of both sides
√14,400= W^2
we want the negative and positive root of the radicand (the number under the radical symbol - 14,400 in this case)
120= w OR -120= w
LENGTHL= 2W= 2(120)= 240 meters
ANSWER: The side lengths are W= 120 m; L= 240 m. Even though W= -120 too, it is not a valid solution in this case since a field cannot have a negative value.
Hope this helps! :)
