Answer:
Step-by-step explanation:
Let x = length of fenced side parallel to the side that borders the river
y = length of each of the other two fenced sides
Then, x + 2y = 4500
<=> x = 4500- 2y
Area = xy = y(4500-2y)
= + 4500y
The graph of the area function is a parabola opening downward.
The maximum area occurs when y = -4500/[2(-2)] = 1125
x = 4500-2y = 2250
To maximize the area, the fenced side parallel to the pone be 2250 feet long, while each of the other two fenced sides should be 1125 feet long.

The total number of students is 50
The number of students that named lacrosse as their favorite sport is given as:
From the circle graph, 38% chose lacrosse.
So, the proportion of students that represent lacrosse is:
Substitute 19 for lacrosse
Multiply both sides by 100
Divide both sides by 38
Rewrite as:
Hence, the total number of students is 50
