An enclosed area is designed using one existing wall, and 72m of fence material. What is the maximum area of the enclosure?
Answers
Answer:
The maximum area possible is 648 squared meters.
Step-by-step explanation:
Let the length of the existing wall be [tex]\ell[/tex].
And let the width of the fence be [tex]w[/tex].
The area of the enclosure will be given by:
[tex]A=w\ell[/tex]
Since the area is bounded by one existing wall, the perimeter (the 72 meters of fencing material) will only be:
[tex]72=2w+\ell[/tex]
We want to maximize the area.
From the perimeter, we can subtract 2w from both sides to obtain:
[tex]\ell=72-2w[/tex]
Substituting this for our area formula, we acquire:
[tex]A=w(72-2w)[/tex]
This is now a quadratic. Recall that the maximum value of a quadratic always occurs at its vertex.
We can distribute:
[tex]A=-2w^2+72w[/tex]
Find the vertex of the quadratic. Using the vertex formula, we acquire that:
[tex]\displaystyle w=-\frac{b}{2a}=-\frac{(72)}{2(-2)}=18[/tex]
So, the maximum area is:
[tex]A=-2(18)^2+72(18)=648\text{ meters}^2[/tex]
The military academy is placing cadets in rows for the parade. All rows must have the same number of cadets. If A company has 60 cadets and B company has 72 cadets, what is the greatest number of cadets who can be in each row? A. 4 B. 6 C. 12 D. 15
Answers
Answer:
C. 12
Step-by-step explanation:
All rows must have the same number of cadets. If A company has 60 cadets and B company has 72 cadets
We find the factors of 60 and 70
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Then the greatest common factor is 12.
Therefore, the greatest number of cadets who can be in each row is 12 cadets.
Option C is the correct option.

h(s) = (s^4-5)^2 derivative
Answers
If h(s) = (s ⁴ - 5)², then by the chain and power rule,
h'(s) = 2 (s ⁴ - 5) • (s ⁴ - 5)'
By the power rule,
(s ⁴ - 5)' = 4s ³
so that
h'(s) = 8s ³ (s ⁴ - 5)
… = 8s ⁷ - 40s ³
Morgan surveyed 260 of the students in her school about their favorite color. 65% said their favorite color was red. How many students' favorite color was red?
Answers
Answer:
169 students
Step-by-step explanation:
From the above question:
Total number of students surveyed = 260
Percentage of students that their favorite colour is red = 65%
Hence: The number of students that their favorite color is red is calculated as:
= 65% × 260
= 65/100 × 260 students
= 169 students
The number of students that their favorite color is red is 169 students

substitute the value of y=-4 in the equation
6x+7*(-4)=4x+4*(-4)
6x-28=4x-16
Combine like terms
6x-4x=28-16
2x=12
x=12/2

On a certain hot summer's day, 340 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $677.00. How many children and how many adults swam at the public pool that day?
Answers
Answer:
Number of children = x = 88
Number of Adults = y = 252
Step-by-step explanation:
Let us represent:
Number of children = x
Number of Adults = y
On a certain hot summer's day, 340 people used the public swimming pool.
Hence:
x + y = 340..... Equation 1
x = 340 - y
The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $677.00.
$1.25 × x + $2.25 × y =$ 677
1.25x + 2.25y = 677..... Equation 2
Let us substitute: 340 - y for x in Equation 2
1.25(340 - y) + 2.25y = 677
= 425 - 1.25y + 2.25y = 677
Collect like terms
- 1.25y + 2.25y = 677 - 425
1y = 252
y = 252
Solving for x
x = 340 - y
x = 340 - 252
x = 88
Therefore the number of children and adults that swam at the public pool that day are: 88 children and 252 Adults.e

CORRECT ANSWER WILL BE BRAINLIEST+20 POINTS!!!!! For the figures below, assume they are made of semicircles, quarter circles, and squares. For each shape, find the area and perimeter. Give your answer as a completely simplified exact value in terms of π (no approximations).
Answers
Answer:
First Picture:
Area = 36pi - 72
Perimeter = 6pi + sqrt(288)
Second Picture:
Area = 576
Perimeter = 48pi + 48
Step-by-step explanation:
First Picture:
Area:
To find the area of the first picture, we need to find the are of quarter of a circle and the area of the triangle (notice we divide by 4 for the circle cause its a quarter of a full circle) .
A of triangle = (b * h )/2 = (12^2)/2 = 72
A of quarter of circle = (r^2 * pi)/4 = (144*pi*)/4 = 36pi
If you subtract the circle by the triangle, you get the shaded area:
36pi - 72
Perimeter:
We need to find the curve and the hypotenuse of our triangle (again, since we only have a quarter of a circle we must divide our perimeter by 4).
hypotenuse = sqrt (12^2 + 12^2) = sqrt (288)
curve = (2*pi*r) / 4 = 24pi / 4 = 6pi
So if we add these, we should have the perimeter
6pi + sqrt (288)
Second Picture:
Area:
we just need to know the area of the square because the semi circles cancel out cause they have the same diameter.
square = 24 * 24 = 576
576
Perimeter:
we need the perimeter of a semicircle and the sides of the square.
semi circle = d*pi = 24pi
sides of square = 24
Now our sum is...
(semi circle ) 2 + (sides of square) 2 = answer
Because our perimeter consists of two semicircles and two sides of the square. And this gives us...
answer = (24pi) 2 + (24) 2 = 48pi + 48
48pi + 48

In translations, points like X become X’ and Z becomes Z’, W becomes W’ and so on.
So let’s focus on point X of the original shape. To get from X to X’ , we just shift one point to the right and one point up. Therefore we know the whole shape was translated one unit right and one unit up.
