A pigpen is to be enclosed using 640 m of fencing along three of its sides, the fourth side being a barn. Determine the dimensions of the pen that will maximize the area (100 PTS + BRAINLIEST)
Answers
Answer:
[tex]W_{max}=320m\\ L_{max}=160m[/tex]
Step-by-step explanation:
Since we know we only have 640 feet of fence available, we know that L + W + L = 640, [tex]\implies [/tex] 2L + W = 640. This allows us to represent the width, W, in terms of L: W = 640 – 2L
Remember, the area of a rectangle is equal to the product of its width and length, therefore,
[tex]A_{\rm pigpen}=L(640-2L)\implies 640L-2L^2[/tex]
Notice that, quadratic has been vertically reflected, since the coefficient on the squared term is negative, so the graph will open downwards, and the vertex will be a maximum value for the area.
recall,
[tex]x_{max}=-b/2a[/tex][tex]f(x)_{max}=f(x_{max})[/tex]Since our function is A(L)=640L-2L², we get
a=-2b=640plug in the value of a and b into the first formula:
[tex]L_{max}=-(640)/2(-2)\implies 160 [/tex]
[tex]A(L)_{max}=640(160)-2(160)^2\implies 51200 [/tex]
hence,the dimensions of the pen that will maximize the area are L=160m and W=51200/160=320m
and we're done!
Answer:
width (x) = 160 m
length (y) = 320 m
(refer to the attached diagram)
Step-by-step explanation:
**see attached diagram**
Let x = width of the pig pen
Let y = length of the pig pen
(where length > width)
Given:
Fence = 640 m4th side is the barn⇒ 2x + y = 640 m
⇒ y = 640 - 2x
Area of the pig pen = width × length
⇒ f(x) = xy
Substituting y for y = 640 - 2x:
⇒ f(x) = x(640 - 2x)
= 640x - 2x²
Now we have a function for the area of the pig pen, to find the value of x that will maximize the area, differentiate the function:
⇒ f'(x) = 640 - 4x
Set it to zero and solve for x:
⇒ f'(x) = 0
⇒ 640 - 4x = 0
⇒ 640 = 4x
⇒ x = 160
Substitute the found value of x into y = 640 - 2x to find the length:
⇒ y = 640 - 2(160) = 320
Therefore, the dimensions of the pen that will maximize the area are:
width (x) = 160 mlength (y) = 320 m

FIND THE FOLLOWING:

Answers
80
60
REASON:
1)Any angles opposite eachother is a cross with straight lines are equal. Therefore angle DOE is also 40. We know DOF is 120 so EOF must be 120-40=80 (which is DOF-DOE). BOC is opposite EOF so it also equals 80.
2) We know that angles on 1 straight line equal to 180 degrees. And we have to angles on a straight line but we are missing one which is COD. So we do (180-BOC-the angle we are given) 180-80-40= 60

Based off the logo (picture attached), what should be the total height, in feet, of the logo on the door?
Answers
Answer:
Clair, since there isn't an attached picture, we don't know some info
Step-by-step explanation:
but here is how you can figure this out....
they tell use to give 6 inches on each side of the door, so the total width of the logo can be 2 feet wide. Because the door is 3 feet wide. Now use that to find the height. find the height to width ratio of the logo, so if the logo is 4 feet wide and 6 feet tall it's 6/4 or 1.5 ratio, use that and multiply by the 2 that we know the width can be on the door. so 2*1.5 = 3. the height of the logo would be 3 feet tall and 2 feet wide on the door. see?
just find the ratio of the logo, and multiply that by 2 :) to find the height on the door, got it?

a. Which cost category varies the least among the different types of colleges? Can you explain why this category varies so little?
b. Ignoring the "other expenses" category, the general trend is for all categories to cost more as you look down the chart from two-year public colleges to four-year private colleges. However, one category is an exception to this trend. Which category? Can you explain why?
Answers
The question indicated above speaks to expense analysis for anonymous colleges. See the details of the analyses below.
From the pictorial representation, which cost category varies the least among the different types of colleges?The cost category that varies the least amongst the various types of colleges is Books and supplies. Notice that at no point did it go below 1,097, nor above, 1,350.
The categories that do not cost more as one goes down the chart (apart from other expenses) are:
Books and supplies and Transportation.Books and supplies went from: $1,350 to $1,107, to 1,107, and then to 1097. Hence decreasing gradually over time.
Transportation also decreased over time starting out from $2,152, to $2,099, to 2,099 and then flatting out at $1,571.
It may be explained that the cost of books is on the decline as more and more people prefer online reading while the cost of transportation is declining as more and more students use their cars or vehicles to the college, hence driving down the cost of transportation.

If A is the center of the circle, then which statement explains how segment GH is related to segment FH?
Circle A with inscribed triangle EFG; point D is on segment EF, point H is on segment GF, segments DA and HA are congruent, and angles EDA and GHA are right angles.
segment GH ≅ segment FH because arc EF ≅ arc GF
segment GH ≅ segment FH because the inscribed angles that create the segments are congruent.
segment GH ≅ segment FH because the tangents that create the segment FG share a common endpoint.
segment GH ≅ segment FH because segment FG is perpendicular to a radius of circle A.
Answers
Statement fourth the segment GH ≅ segment FH because segment FG is perpendicular to a radius of circle A if Circle A with inscribed triangle EFG; point D is on segment EF, point H is on segment GF, segments DA and HA are congruent, and angles EDA and GHA are right angles.
What is a circle?It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
We have AH as the radius and FG as a chord
AH is perpendicular to FG, AH⊥FG
As we know that a line passing through the center and perpendicular to the chord, bisects the chord.
∴ AH bisects FG
∴ FH = GH
Thus, the segment GH ≅ segment FH because segment FG is perpendicular to a radius of circle A if Circle A with inscribed triangle EFG; point D is on segment EF, point H is on segment GF, segments DA and HA are congruent and angles EDA and GHA are right angles.

The quotient and remainder for the last row of the synthetic division 3, 0, 4, 0, 1 are 3x³ + 4x, and 1 respectively.
The option representing this is, a. 3x³ + 4x R1.
What is synthetic division?Synthetic division is a short method of dividing a polynomial p(x) by another polynomial (x - c), to get the quotient and remainder.
The last row represents the quotient and remainder, the last digit being the remainder, and the others being the quotient multiplied by leading powers of x, starting from x⁰, starting from the second last term of the last row.
How to solve the question?In the question, we are given the last row of a synthetic division as 3, 0, 4, 0, 1, and we are asked to find the quotient of the division.
The last number, 1 represents the remainder and can be written as R1.
Now we move from the back to the front and multiply every number with the leading power of x, starting from x⁰.
0 gives 0 * x⁰ = 04 gives 4 * x¹ = 4x0 gives 0 * x² = 03 gives 3 * x³ = 3x³.Therefore, the quotient and remainder for the last row of the synthetic division 3, 0, 4, 0, 1 are 3x³ + 4x, and 1 respectively.
