A farmer decides to make three identical pens with 88 feet of fence. The pens will be next to each other sharing a fence and will be up against a barn. The barn side needs no fence. What dimensions for the total enclosure (rectangle including all pens) will make the area as large as possible?
Answers
Answer:
The long fence, AC = 44 feet
4 shorter segments at 11feet each = 44 feet
Area = 484 ft^2
Step-by-step explanation:
The three pens will share one fence section parallel to the barn, we'll call it AB. Each pen will need two side fence segments, from the front fence to the barn. We'll call those portions AC. We need four of them: two for the outer sides and two more to divide up the space equally among the three pens. The total area would be AB*AC.
We know that AC + 4AB = 88 feet.
or AC = (88feet - 4AB)
Area = AB(88feet - 4AB)
Area = 88AB - 4AB^2
To maximize the area, we can take the first derivative and set it equal to zero:
Area' = 88 - 8AB
0 = 88 - 8AB
AB = 11 feet
AC = (88 - 4AB)
AC = (88 - 44)
AC = 44 feet
The fours segments of fence:
AC + 4AB = 88 feet
(44) + 4(11 feet) = 88feet
Area = 44' x 11 ft' = 484 ft^2

What is the equation of a line perpendicular to minus x plus 2 equal y that intersects the line at open parentheses minus 1. 5 comma space 3. 5 close parentheses ?.
Answers
The required equation of a line perpendicular is y = x + 5
Given the equation y = -x + 2, the slope of the line is -1
The slope of the line perpendicular will be m -1/-1 = 1.Given the point (-1.5, 3.5)Substitute the slope and the point into the point-slope form of the equation expressed as:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-3.5=1(x-(-1.5))\\y-3.5=x+1.5\\y=x+1.5+3.5\\y=x+5[/tex]
Hence the required equation of a line perpendicular is y = x + 5

$10 for apple, $8 for oranges, $6 for bananas, and $24 total
EXPLANATION:
First let’s round round to the nearest dollar.
Apples cost 1.75 for a pound, that rounded is 2.00
So $2.00 is the estimated amount.
Oranges cost 2.35 per pound. That rounded is 2.00
So the estimated amount is $2.00
Bananas cost 1.50 per pound. That rounded is also 2.00.
So the estimated amount is $2.00
Now we know that rounded amount we just multiply.
If apples cost about 2.00 per pound and she bought 5 pounds just multiply by 5.
2.00 x 5 = $10.00
She paid about $10.00 for apples
If she bought 4 pounds of oranges and one pound of oranges cost about 2.00, multiply 2 by 4.
2.00 x 4 = 8.00
She paid about $8.00 for oranges.
If bananas cost 2.00 per pound and she bout 3 pounds, multiply by 3.
2.00 x 3 = $6.00
She paid $6.00 for bananas.
Now to find the total amount she spent add them all together.
$10.00
$ 8.00
$ 6.00

$24.00

We plot the point (-5,0) on the coordinate plane.
Then, we reflect it over the y-axis.
Remember the rule:
If a point has coordinates (x, y), and the point is reflected over the y-axis, the new point's coordinates are: (-x,y)Let's use this rule now.
We reflect (-5,0) over the y-axis.
