Answer:
Step-by-step explanation:
42=w(w-1)
w^2-w-42=0
w^2-6w+7w-42=0
(w+7)(w-6)=0
w=-7or w=6
note: we ignore the negative value as measurement cannot be negative
width=6metres
length=5metres
Since it is a square field, the sides are the same. √1255= <span>35.4259791678
Rounded down, each side is about 35 yards.</span>
$12 is the answer.
Hope this helps!

Answer:
Point (50,166.67)
Step-by-step explanation:
Incomplete question.
The Revenue function R(x) is
First, we calculate the first derivative
The second derivative is
The point of disminihing returns for the function happens when the second derivative is equal to zero. This is the point where the concavity of the function changes. This happens at x=50:
At point (50,166.67) the function of revenue will be in its point of diminishing returns.
