In response to the given question, we can state that As a result, the square answer is (D) 1 square yard.
what is a square?In Euclidean geometry, a square is an equilateral quadrilateral having four equal sides and four equal angles. It is also known as a rectangle with two adjoining sides that have the same length. A square is an equilateral quadrilateral because it has all four equal sides and all four equal angles. Square angles are 90 degree or straight angles. Moreover, the square's diagonals are evenly spaced and divide at a 90-degree angle. an adjacent rectangle with two equal sides. A quadrilateral with four equal-length sides and four right angles. A parallelogram with two adjacent, equal sides that create a right angle. Rhombus with straight sides.
Then, calculate the length of each side of the square enclosure.
Vanessa utilised the garage's outer wall for one of the sides, so she only needed to create three more sides. She utilised three yards of fence for these three sides, therefore each must be three-thirds of a yard long.
As a result, the area of the enclosure is equal to the length of one side squared:
Area = side length + 1 yard + 1 yard = 1 square yard
As a result, the answer is (D) 1 square yard.

What is a matrix?A matrix, sometimes known as matrices, is a rectangular array or table of letters, numbers, or other symbols organized in rows and columns that are used to represent a mathematical object or a characteristic of one.
In linear algebra, matrices describe linear mappings and enable explicit computations. As a result, a significant portion of linear algebra involves the study of matrices, and the majority of the characteristics and operations of abstract linear algebra may be described in terms of matrices. The composition of linear maps, for instance, is represented by matrix multiplication.
Not every matrix has a connection to linear algebra. This is especially true for incidence matrices and adjacency matrices in graph theory.
The matrix A is:
| 0 1 1 |

A box contained red, orange and white beads, 20% of the beads were red. Later, the number
of red beads was increased by 5% and the total number of orange beads and white beads
were increased by half. Mary found that there were 123 beads more. How many beads were in the
box at first?
Answer:
Step-by-step explanation:
Let the total number of beads in the box be x.
Then, the number of red beads in the box is 20% of x = 0.2x.
After increasing the number of red beads by 5%, the number of red beads becomes 1.05 times the original number of red beads, which is 1.05(0.2x) = 0.21x.
The total number of orange and white beads is (100% - 20%) = 80% of x, which is 0.8x.
After increasing the number of orange and white beads by half, the total number becomes 1.5 times the original number, which is 1.5(0.8x) = 1.2x.
So, we have the equation: 0.21x = 0.2x + 123 - 1.2x
Simplifying this equation, we get:
0.01x = 123
x = 12,300
Therefore, the box originally contained 12,300 beads.
Bob and Kevin bought a lottery ticket and won $100 000. Since they paid different amounts for the winning ticket, Bob received $10 000 more than two times what Kevin received. How much did each person receive?
answer: Kevin received $30,000, and Bob received $70,000.
According to the problem, Bob received $10,000 more than two times what Kevin received. So, Bob received:
2X + $10,000
We also know that the total amount won is $100,000. Therefore, we can write the equation:
X + (2X + $10,000) = $100,000
Simplifying the equation, we get:
3X + $10,000 = $100,000
3X = $90,000
X = $30,000
Therefore, Kevin received $30,000, and Bob received:
2X + $10,000 = 2($30,000) + $10,000 = $70,000
So Bob received $70,000.

What is linear regression ?
Linear regression is a statistical method that is used to establish the relationship between two variables, usually represented as a straight line. It is used to determine the extent to which one variable is dependent on the other variable, and to make predictions based on this relationship.
Using linear regression, we want to find the equation of the line of best fit in the form y = mx + b, where m is the slope and b is the y-intercept.
First, we need to calculate some sums:
∑x = 28
∑y = 45
∑xy = 224
∑x² = 140
∑y²= 275
Using these sums, we can calculate the slope m:
m = (n∑xy - ∑x∑y) / (n∑x² - (∑x)²)
m = (7(224) - (28)(45)) / (7(140) - (28)^2)
m = 1.19
Now we can use the slope to calculate the y-intercept b:
b = (∑y - m∑x) / n
b = (45 - (1.19)(28)) / 7
b = -0.37
Therefore, the equation of the line of best fit is y = 1.19x - 0.37.

Step-by-step explanation:
Calculate the radius of the following circle. Round to two decimal places when necessary.
(x+3)² + (y +7)² =121
Answer:
The equation of the given circle is:
(x + 3)² + (y + 7)² = 121
This equation is in standard form, which is:
(x - h)² + (y - k)² = r²

What is the Equation of the Perpendicular Line to an Equation?To find the equation of a line that is perpendicular to y = 2x + 4 and goes through the point (6, 4), we first need to determine the slope of the given line.
The equation y = 2x + 4 is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Therefore, the slope of the given line is 2.
The slope of a line perpendicular to this one will be the negative reciprocal of 2, which is -1/2.
So the equation we are looking for will have a slope of -1/2 and will pass through the point (6, 4). We can use the point-slope form of the equation of a line to find it:

the price p of a certain computer system decreases immediately after its introduction and then increases. if the price P is estimated by the formula P= 170t^2- 1700t + 6400, where t is the time in months from its introduction, find the time until the minimum price is reached
The time until the minimum price is reached is 5 months. After this time, the price will start to increase again.
Define the term price?Price is the amount of money that must be paid to acquire a product or service, usually expressed in currency units such as dollars or euros.
The price of the computer system is given by the formula:
P = 170t² - 1700t + 6400
To find the time until the minimum price is reached, we need to find the value of t that corresponds to the vertex of the parabola described by this formula. The vertex is the point at which the price reaches its minimum value.
The formula for the x-coordinate of the vertex of a parabola in standard form (ax² + bx + c) is:
x = -b/2a
In this case, the formula for the price of the computer system is:
P = 170t² - 1700t + 6400
So we can see that a = 170, b = -1700, and c = 6400. Substituting these values into the formula for the x-coordinate of the vertex, we get:
t = -b/2a = -(-1700)/(2×170) = 5

The height of a flare is given by the equation h(t)= -0.5t² +16t+22 where h is the height of the flare in metres and is the time the flare has been in the air in seconds. How long will the flare be in the air if it fizzles out at a height of 10 m above ground?
Answer:
the flare will be in the air for approximately 29.09 seconds before fizzling out at a height of 10 meters above ground.
Step-by-step explanation:
To find out how long the flare will be in the air, we need to find the time it takes for the flare to reach a height of 10 meters.
Setting h(t) to 10 and solving for t:
-0.5t² +16t+22 = 10
-0.5t² +16t+12 = 0
Using the quadratic formula:
t = (-b ± √(b² - 4ac)) / 2a
Where a = -0.5, b = 16, and c = 12:
t = (-16 ± √(16² - 4(-0.5)(12))) / 2(-0.5)
t = (-16 ± √(256 + 24)) / -1
t = (-16 ± √280) / -1
t ≈ -1.09 or t ≈ 29.09
Since time cannot be negative, we can ignore the negative root. Therefore, the flare will be in the air for approximately 29.09 seconds before fizzling out at a height of 10 meters above ground.

What is function ?
In mathematics, a function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range) with the property that each input is related to exactly one output. Functions are often represented by a formula or rule that describes how to compute the output value from the input value.
The towing cost, C, can be expressed as a function of miles towed, x, using the given information as follows:
C(x) = 75 + 2x
where x is the number of miles towed.
To find the cost of towing a car 14 miles, we can substitute x = 14 into the function:
C(14) = 75 + 2(14)
= 75 + 28
= $103
Therefore, the cost of having a car towed 14 miles is $103.
