Answer:
125000 square feet
Step-by-step explanation:
Since there are only three sides of the rectangle, the perimeter of the fence is:
Let x and y be the sides of the rectangle, we are left with:
2 * x + y = 1000
solving for and:
y = 1000 - 2 * x
The area of the corral is:
A = x * y
replacing
A = x * (1000 - 2*x)
A = 1000 * x - 2*x^2
to find the maximum for the parabolic function A = 1000 * x - 2*x^2
The function has a maximum since the quotient before x ^ 2 is negative: -2 <0
Amax = c - b^2 /4*a
where a = -2, b = 1000, c = 0
A max = 0 - 1000^2/(4 * (- 2))
A max = 125000 ft^2
The maximum possible area of the pen is 125000 square feet.

Answer:
19.4 dollars
Step-by-step explanation:
3.45= 3/4 lb times 5.625
7.5 lb
3.45 times 5.625=19.4
Answer:
n=-4/3
Step-by-step explanation:
So the equation is -2/3n+7=15
First you subtract 7 from both sides: -2/3n+7-7=15-7 : -2/3n=8
Next multiply by 1/-2 on both sides, canceling out the -2 on the left and dividing 8 by -2 on the right: 3n=-4
Next divide by 3 on both sides
Answer: n=-4/3
