Answer:
The dimensions that maximize the area of the garden are 200 feet by 100 feet.
The largest area for the garden would be 20,000 square feet
Step-by-step explanation:
Let the length of the garden be x feet and the width be y feet. One side of the garden is adjacent to the barn, which is 50 feet long. Since only three sides need to be fenced, we can set up the following equation for the perimeter:
x + 2y = 400
We need to find the dimensions that will maximize the area of the garden, which is given by A = xy. First, we will express y in terms of x using the perimeter equation:
y = (400 - x) / 2
Now, substitute y in the area equation:
A(x) = x(400 - x) / 2
A(x) = (400x - x^2) / 2
To maximize the area, we need to find the critical points of the function A(x). We do this by taking the first derivative and setting it to 0:
A'(x) = (400 - 2x) / 2
A'(x) = 200 - x
Now, set A'(x) to 0 and solve for x:
200 - x = 0
x = 200
Now, substitute x = 200 back into the equation for y:
y = (400 - 200) / 2
y = 200 / 2
y = 100
So, the dimensions that maximize the area of the garden are x = 200 feet (length) and y = 100 feet (width). Now we can find the largest possible area:
A = xy
A = (200)(100)
A = 20,000 square feet
The largest possible area for the garden is 20,000 square feet.

A new theater is being built for the city ballet. The balcony has 90 seats. The
floor has 15 rows with x seats in each row. The number of people in the
theater must be under 240 to meet fire safety regulations.
What is the solution of this inequality, and what is its meaning?
The solution to the inequality is x ≤ 10, which means that each row of seats on the floor must have 10 seats or fewer in order to meet the fire safety regulations.
What is inequality?
In mathematics, the inequality of two lines refers to the relationship between the slopes and y-intercepts of two different lines on a coordinate plane. Specifically, if the slope of one line is greater than the slope of another line, and their y-intercepts are not equal, then the inequality symbol (< or >) can be used to represent their relationship. For example, if line A has a slope of 2 and a y-intercept of -3, and line B has a slope of 1 and a y-intercept of 1, we can write A > B to represent that line A is steeper than line B.
To solve this problem, we need to use the information given to us to set up an inequality that represents the total number of seats in the theater and then use that inequality to determine the maximum number of people that can be in the theater while still meeting the fire safety regulations.
Let's start by calculating the total number of seats in the theater. We know that there are 90 seats in the balcony and 15 rows on the floor. We don't know the exact number of seats in each row, but we do know that each row has the same number of seats, which we will call x. Therefore, the total number of seats in the theater is 90 + (15 × x)
Now we can set up an inequality to represent the maximum number of people that can be in the theater while still meeting the fire safety regulations. We know that this number must be less than or equal to 240. Therefore, our inequality is 90 + (15 × x) ≤ 240
Now we can solve for x by first subtracting 90 from both sides of the inequality,
15 × x ≤ 150
Next, we can divide both sides of the inequality by 15,
x ≤ 10
Therefore, the solution to the inequality is x ≤ 10, which means that each row of seats on the floor must have 10 seats or fewer in order to meet the fire safety regulations.
To check this solution, we can plug x = 10 into our expression for the total number of seats,
Total number of seats = 90 + (15 × 10) = 240
This confirms that the maximum number of people in the theater is 240, which is the limit imposed by the fire safety regulations.

50 Points! Multiple choice algebra question. Transform both sides of each equation to determine which is a polynomial identity. Photo attached. Thank you!
The only equation that is a polynomial identity is (A), (c+d)³ = c³ - d³ + 3cd(c + d).
How to express the valueIt should be noted that to determine which equation is a polynomial identity, we need to simplify both sides of each equation and see if they are equal for all values of c and d.
(A) (c+d)³ = c³ + 3c²d + 3cd² + d³
= c³ - d³ + 3cd(c + d)
The left-hand side can be expanded using the binomial formula. The right-hand side is a polynomial of degree 3, so we can see that equation (A) is a polynomial identity.
(B) (c+d) = c + d³ + 3cd(c + d)
= d³ + c³ + 3cd(c + d) + c + d - c³
= d³ + c³ + 3cd(c + d) + c + d
The right-hand side can be simplified, but it is not equal to the left-hand side for all values of c and d. Therefore, equation (B) is not a polynomial identity.
(C) (c+d)³ = c³ + 3c²d + 3cd² + d³
= c³ + d³ + 3cd(c + d) + cd(c - d)
The right-hand side is not equal to the left-hand side for all values of c and d, so equation (C) is not a polynomial identity.
(D) (c+d)³ = c³ + 3c²d + 3cd² + d³
= c³ - d³ + 3cd(c - d) + c³ + d³
= 2c³ + 3cd(c - d)
The right-hand side is not equal to the left-hand side for all values of c and d, so equation (D) is not a polynomial identity.
Therefore, the only equation that is a polynomial identity is (A), (c+d)³ = c³ - d³ + 3cd(c + d).

A regular octogon is inscribed in a circle with a radius of 14 inches. Find the perimeter of the octogon. Round to 2 decimal places.
The perimeter of the octagon is:
Perimeter = 8s ≈ 100.16 inches
What is the perimeter?
The perimeter is a mathematical term that refers to the total distance around the outside of a two-dimensional shape. It is the length of the boundary or the sum of the lengths of all the sides of a closed figure.
To find the perimeter of the regular octagon inscribed in a circle with radius 14 inches, we need to use the formula:
Perimeter of octagon = 8 x length of one side
Since the octagon is regular, all sides are congruent. Let s be the length of one side of the octagon.
The radius of the circle is 14 inches, which is also the distance from the center of the circle to any vertex of the octagon. We can divide the octagon into eight congruent isosceles triangles, each with base s and legs of length 14 inches. We can then use the Pythagorean theorem to find the length of the base s:
s² = 14² - (s/2)²
s² = 196 - s²/4
5s²/4 = 196
s² = 156.8
s ≈ 12.52
Therefore, the perimeter of the octagon is:

Suppose 16 cars start at a car race. In how many ways can the top 3 cars finish the race
there are 3,360 ways in which the top 3 cars can finish the race.
How to Determine the number of ways?
To determine the number of ways in which the top 3 cars can finish the race, we can use the concept of permutations. A permutation is an arrangement of objects in a specific order. In this case, the order of the cars finishing the race matters.
The number of ways to determine the first place finisher is 16, as any of the 16 cars can finish in first place. Once the first place finisher has been determined, there are only 15 cars remaining, and any one of them can finish in second place. Therefore, there are 15 possible ways to determine the second place finisher.
Similarly, once the first and second place finishers have been determined, there are 14 cars remaining, and any one of them can finish in third place. Therefore, there are 14 possible ways to determine the third place finisher.
To find the total number of ways in which the top 3 cars can finish the race, we can multiply the number of possibilities for each place together:
16 x 15 x 14 = 3,360
Therefore, there are 3,360 ways in which the top 3 cars can finish the race.
It is important to note that this calculation assumes that each car is unique and that there are no ties for any of the top 3 positions. If there were ties, the calculation would become more complicated and would involve combinations as well as permutations.

A researcher is standing in a corner (point c) of a triangler plot. the angle to point a is S76E the angle to point b is N32E The distance between point c and point a is 210 ft and the distance between point c and point b is 150 ft
find the distance between point a and point b
Answer:
We can use the Law of Cosines to find the distance between points a and b.
Using the angles given, we can find the angle between points a and b:
Angle C = 180 - (76 + 32) = 72 degrees
Next, we can use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab cos(C)
where c is the distance between points a and b, a is the distance between point c and point a (210 ft), b is the distance between point c and point b (150 ft), and C is the angle between points a and b (72 degrees).
Plugging in the values:
c^2 = 210^2 + 150^2 - 2(210)(150)cos(72)
c^2 ≈ 21069.27
Therefore, the distance between points a and b is approximately:
c ≈ 145.2 ft

C) 25%
D) 28%
thought i would leave this but ⇒ty to whoever answers this, have an amazing day <3
The percentage of females with brown eyes as follows is 25%.
What is percentage?Percentage is a way of expressing a number as a fraction of 100. It is represented by the symbol "%". The word "percent" means "per hundred".
According to question:Let's assume that the total population of Math town is 100 people for the sake of simplicity. Then, we can use the following information to create a table:
Population Males Females
Total 60 40
Brown eyes 18 ?
From the table, we can see that 60% of the population are males, so there are 60 x 0.3 = 18 males with brown eyes.
We also know that the total population with brown eyes is 28%, so there are 100 x 0.28 = 28 people with brown eyes. Therefore, there must be 28 - 18 = 10 females with brown eyes.
Finally, we can calculate the percentage of females with brown eyes as follows:
% of females with brown eyes = (10 / 40) x 100% = 25%

solve the equation x^2+4x-11=0 by completing the square
To solve the equation x^2 + 4x - 11 = 0 by completing the square, we can follow these steps:
Move the constant term to the right side of the equation:
x^2 + 4x = 11
Complete the square by adding the square of half the coefficient of x to both sides of the equation:
x^2 + 4x + (4/2)^2 = 11 + (4/2)^2
Simplifying the left side:
x^2 + 4x + 4 = 11 + 4
Factor the perfect square on the left side of the equation:
(x + 2)^2 = 15
Take the square root of both sides of the equation:
x + 2 = ±√15
Solve for x by subtracting 2 from both sides:
x = -2 ± √15
Therefore, the solutions to the equation x^2 + 4x - 11 = 0 by completing the square are x = -2 + √15 and x = -2 - √15.

If NP and QS are parallel lines and ∠NOM = 130° then the value of ∠POM is 50°.
What is parallel line?Parallel lines are two or more lines in a plane that do not intersect, regardless of how far apart they are.
Despite being located at different distances from one another, parallel lines always have the same slope, which is the same steepness and direction.
Since NP and QS are parallel lines, we have:
∠NOM + ∠MOP = 180° (because NOM and MOP are on a straight line)
Also, the alternate interior angles NOM and POM are equal, so:
∠NOM = ∠POM
Substituting this into the first equation gives:
∠POM + ∠MOP = 180°
We can now solve for ∠POM by substituting the given value:
130° + ∠POM = 180°
∠POM = 50°

1. The total amount of your emergency fund will be $11,403.75.
2. $8,552.81 is in the CD, and $2,850.94 is in the regular savings account.
What is the total amount of your emergency fund?Your FICA deduction is 7.65% of your gross income:
7.65% of $4,520.00 = $345.98
Your federal tax withholding is 11.75% of your gross income:
11.75% of $4,520.00 = $531.40
Your state tax withholding is 8.5% of your gross income:
8.5% of $4,520.00 = $384.40
Your total deductions are:
= $345.98 + $531.40 + $384.40
= $1,261.78
Your monthly income after deductions is:
= $4,520.00 - $1,261.78
= $3,258.22
Your fixed expenses are 30% of your realized income:
= 30% of $3,258.22
= $977.47
Your monthly savings amount is:
= $3,258.22 - $977.47
= $2,280.75
You saved 5 months' worth in an emergency fund, so the total amount in your emergency fund is:
= 5 x $2,280.75
= $11,403.75

How much is in the CD and savings account?You placed 75% of your emergency fund in a 60-day CD at a 5.25% APR:
= 75% of $11,403.75 = $8,552.81
You placed the remaining 25% of your emergency fund in a regular savings account at a 3.8% APR:
= 25% of $11,403.75
= $2,850.94.

The equation a² + b² = c² represents the Pythagorean theorem.
What is the Pythagorean theorem?This is a theorem that states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b).
The Pythagorean theorem is used to find the length of one of the sides of a right-angled triangle when the lengths of the other two sides are known.
To solve the problem, you need to have at least two side lengths given. Then, you can use the equation to find the length of the third side. For example:
If you know the lengths of sides a and b and need to find the length of the hypotenuse (c):
Plug in the known values for a and b into the equation and solve for c.
Example: If a = 3 and b = 4, then 3² + 4² = c², which gives 9 + 16 = c², so c² = 25, and c = sqrt(25) = 5.

8x+5+3x+8=90
Answer:
x = 7
Step-by-step explanation:
8x + 5 + 3x + 8 = 90
11x + 5 + 8 = 90
11x + 13 = 90
11x = 77
x = 7
Let's Check
8(7) + 5 + 3(7) + 8 = 90
56 + 5 + 21 + 8 = 90
61 + 21 + 8 = 90
82 + 8 = 90
90 = 90
So, x = 7 is the correct answer!
Answer:
7
Step-by-step explanation:
First, collect common factors. This means put the x's together and the regular numbers together.
8x+3x=11x
5+8=13
11x+13=90
Subtract 13 from both sides
11x+13=90
-13 -13
11x=77
Divide 77 by 11
x=7

The length of a rectangular poster is 2 more inches than two times its width. The area of the poster is 84 square inches. Solve for the dimensions (length and width) of the poster.
Step-by-step explanation:
w = width
2w + 2 = Length
Area = W x L = 84 = w (2w+2)
84 = 2w^2 + 2w
0 = 2w^2 + 2w - 84 Use Quadratic Formula
a = 2 b=2 c = -84
to find
W = 6 then L = 14 inches

Given: if p(x,y) is the point on the unit circle defined by the real number theta.
We have to find the value of the csc theta.
P(x,y) is the point on the unit circle (the unit circle has a radius of 1 and center (0,0))
Now in a diagram, we can see that
OA= x
AP= y
radius OP =1
∠POA =θ
Now in ΔAOP
Cscθ = hypotenuse/opposite side
Cscθ = OP/AP
Cscθ = 1/y
Hence, the value of Cscθ is 1/y.
