Y=5x+3 the domain is 3 but the answer is B.8
Step-by-step explanation:
Let the side parallel to the river be x meter and the other two sides be of y meter, then
The area of the rectangle is
Substitute into to express the area in a single variable x as,
Differentiate A(x) with respect to x and equate to zero as,
x=150
Here, at is maximum
Therefore, the dimension is:
Length of side parallel to the river: x=150 m.
Length of other two side: m.
