Answer:
100m by 50m.
Step-by-step explanation:
Let the dimension of the rectangular pen be x and y
Area, A(x,y)=xy
Let the side opposite her barn = x
Since she wants to fence only three side
Perimeter = x+2y
Length of Fencing Available = 200m
Therefore:
We want to maximize the area of the pen, A(x,y).
Substituting x=200-2y into A(x,y)=xy
To maximize A(y), we find its derivative and solve for the critical points.
To ensure that this is a maximum, we use the second derivative test.
This is negative and thus, y=50 is a maximum point.
Recall:
x=200-2y
x=200-2(50)
x=200-100
x=100m
Therefore, the dimensions of the pen that has the largest area are 100m by 50m.
Answer:
See the image below.
Step-by-step explanation:
The decimals 0.43 and 0.39 are equivalent to 43/100 and 39/100. These decimals lie between 0 and 1.
Draw a number line, mark off and label the multiples of 0.10(e.g 0.10, 0.20) in the interval 0-1.
Mark 0.43 between 0.4 and 0.5, a little closer to 0.4.
Mark 0.39 between 0.3 and 0.4, just behind 0.4.
Since 0.39 is smaller than 0.43( 0.39 lies on the left to 0.43), the inequality is:
0.39<0.43
