Therefore, the perimeter of a quadrilateral at the given vertices is 12.76 units.
What is quadrilateral?A quadrilateral is a four-sided polygon with four edges and four corners that is used in geometry. The Latin words quadri, a variation of four, and latus, meaning "side," are the source of the name.
Define edges and corners.A face is a flat surface, an edge is a straight line connecting two faces, and a vertex is the corner of the form. Faces, edges, and vertices of three-dimensional forms are all unique. In the course of our daily activities, we come into contact with numerous things of all sizes and forms.
The length of each side:
CD: C(2,4) and D(1,1) = sqrt((1-2)^2 + (1-4)^2) = sqrt(1 + 9) = sqrt(10)
DE: D(1,1) and E(5,0) = sqrt((5-1)^2 + (0-1)^2) = sqrt(16+1) = sqrt(17)
EF: E(5,0) and F(3,4) = sqrt((3-5)^2 + (4-0)^2) = sqrt(4+16) = sqrt(20)
FC: F(3,4) and C(2,4) = sqrt((2-3)^2 + (4-4)^2) = sqrt(1) = 1
Perimeter of the quadrilateral = sum of the lengths of all four sides:
Perimeter = sqrt(10) + sqrt(17) + sqrt(20) + 1
Calculating, perimeter = 3.162+4.123+4.472+1 = 12.7557 and rounding to the nearest hundredth, it is 12.76

b) How many words will the code have in 10 years?
Answer:
a). t = 5 years.
b). n = 25000 words.
Step-by-step explanation:
From the question it have been given a formula
which is n = 2450t + 500
a) The year
n = 12750 words
n = 2450t + 500
= 12750 = 2450t + 500
= 12750 - 500 = 2450t
= 12250 = 2450t
= 12250/2450 = 2450t/2450.
5 years = t
Or

We decide on 320 as the best-predicted value. EV(node 4) = 320. The answer is option (a).
What is Probability?
Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes. Statistics is the study of occurrences that follow a probability distribution.
Probability of S1 = 0.6
Probability of F = 0.40

The likelihood that the basketball player will convert at least six of his or her eight free throw tries is 0.32.
What is meant by probability ?The simple definition of probability is the likelihood that something will occur. We can discuss the probabilities of different outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics refers to the study of events subject to probability.
The ratio of all potential cases to the number of cases that are favorable to an event determines its likelihood when there is no reason for us to believe that any one of these circumstances will happen more frequently than any other, making them all equally likely.
The likelihood that an event will occur is quantified by probability. The probability of an event is the relative frequency throughout time of that event. Probabilities are all numbers between 0 and 1, inclusive—that is, any numbers between 0 and 1.

Using any method(s), solve Angle K H P when h = 16.1, p = 24.9 and k = 12.8 (trigonometry)
The angles of the triangle KHP are P ≈ 118.555°, H ≈ 34.614°, K ≈ 26.844°, respectively.
How to determine the measures of missing angles in a triangleHere we have the case of a triangle where the lengths of three sides are known and measures of angles must be determined. The missing angles can be found by means of law of cosine, whose equations related to the triangle are introduced below;
p² = h² + k² - 2 · h · k · cos P
h² = p² + k² - 2 · p · k · cos H
k² = h² + p² - 2 · h · p · cos K
Given;
h, k, p - Sides
H, K, P - Angles
If we know that h = 16.1, p = 24.9 and k = 12.8, then the measures of the angles are;
cos P = (p² - h² - k²) / (- 2 · h · k)
cos P = (24.9² - 16.1² - 12.8²) / (- 2 · 16.1 · 12.8)
cos P = - 0.478
P ≈ 118.555°
cos H = (h² - p² - k²) / (- 2 · p · k)
cos H = (16.1² - 24.9² - 12.8²) / (- 2 · 24.9 · 12.8)
cos H = 0.823
H ≈ 34.614°
cos K = (k² - h² - p²) / (- 2 · h · p)
cos K = (12.8² - 16.1² - 24.9²) / (- 2 · 16.1 · 24.9)

Juan builds this pedestal for a trophy.
What is the volume of the pedestal?
Answer:
112 in³------------------------------------
The pedestal is the combination of two rectangular prisms.
One of them has dimensions:
9 in by 2 in by 4 inIts volume is:
V = 9*2*4 = 72 in³The other one has dimensions:
(9 - 2 - 2) = 5 in by 2 in by 4 inIts volume is:
V = 5*2*4 = 40 in³Total volume is:
72 + 40 = 112 in³Answer:
112 in³
Step-by-step explanation:
The pedestal is made up of two rectangular prisms.
[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Volume of a rectangular prism}\\\\$V=w\cdot l\cdot h$\\\\where:\\ \phantom{ww}$\bullet$ $w$ is the width of the base. \\ \phantom{ww}$\bullet$ $l$ is the length of the base.\\\phantom{ww}$\bullet$ $h$ is the height of the prism.\\\end{minipage}}[/tex]
The dimensions of the largest rectangular prism are:
w = 2 inl = 9 inh = 4 inTherefore, the volume of the largest rectangular prism is:
[tex]\begin{aligned}\implies V&=2 \cdot 9 \cdot 4\\&=18 \cdot 4\\&=72\;\rm in^3\end{aligned}[/tex]
The dimensions of the smaller rectangular prism are:
w = 2 inl = 9 - 2 - 2 = 5 inh = 4 inTherefore, the volume of the smaller rectangular prism is:
[tex]\begin{aligned}\implies V&=2 \cdot 5 \cdot 4\\&=10\cdot 4\\&=40\;\rm in^3\end{aligned}[/tex]
The volume of the pedestal is the sum of the volumes of the largest and smaller rectangular prisms:
[tex]\implies V=72+40=112\; \rm in^3[/tex]
Therefore, the volume of the pedestal is 112 in³.

What is Combination in Mathematics?
In mathematics, a combination is a way of selecting a certain number of items from a larger set of items, without regard to the order in which the items are selected. It is a way to count the number of distinct subsets of a given size from a larger set.
The formula for combination is:
(n!) / (r! * (n-r)!)
The company Sea Esta has 12 members on its board of directors, and they need to elect a president, vice-president, secretary, and treasurer. The number of ways to elect these four positions is determined by using the formula of combination, which is:
Where n is the total number of options (in this case, the number of board members) and r is the number of positions to be filled (in this case, 4).
So, the number of ways to elect a president, vice-president, secretary, and treasurer is:
(12!) / (4! * (12-4)!) = (1211109) / (4321) = 495
Therefore, the company Sea Esta can elect a president, vice-president, secretary and treasurer in 495 different ways.

What is a Right Angle Triangle ?
A right triangle is a triangle having one right angle or two perpendicular sides. It is also referred to as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle. The relationship between the sides and various angles of the right triangle serves as the basis for trigonometry.
The Pythagorean theorem, often known as Pythagoras' theorem, in Euclidean geometry relates the three sides of a right triangle. This statement states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
In the triangle 2 angles are 90° and 45° respectively.
The third angle is = 180°+90°-45°=45°
The triangle is issosceles triangle
So the side which is not x is 16.
Now by using Pythagoras Theorem
x = √16^2+16^2 = 16√2
The value of x is 16√2
The value of y is y^2 + 16^2 = 16√2^2
y^2 = 512 - 256
y^2 = 256

It is given that:
f: R → R is a continuous function such that:
[tex]f(x+y)[/tex] = [tex]f(x) + f(y)[/tex] ∀ x , y ∈ R (Equation-1)
Now, let us assume f(1)=k
Also,
f(0) = 0( Since, f(0)=f(0+0)
That is,
f(0)=f(0)+f(0)
By using property (1)
Also,
f(0)=2f(0)
That is,
2f(0)-f(0)=0
That is,
f(0)=0 )
Also,
f(2)=f(1+1)
That is,
f(2)=f(1)+f(1) ( By using property (1) )
i.e.
f(2)=2f(1)
That is,
f(2)=2k
Similarly for any m ∈ N
f(m)=f(1+1+1+...+1)
That is,
f(m)=f(1)+f(1)+f(1)+ ....... +f(1) (m times)
That is,

Now,
f(1) = [tex]f(\frac{1}{n} +\frac{1}{n} +......\frac{1}{n} )[/tex]
f(1) = [tex]f(\frac{1}{n} )+f(\frac{1}{n} )+......f(\frac{1}{n} )[/tex]
f(1) = n [tex]f(\frac{1}{n} )[/tex]
f(1) = k
[tex]f(\frac{1}{n} )[/tex] = k * [tex]\frac{1}{n}[/tex]
Also,

Then,
[tex]f(\frac{p}{q})[/tex] = [tex]f(\frac{1}{q} )+ f(\frac{1}{q} )+ .....f(\frac{1}{q} )[/tex]
[tex]f(\frac{p}{q})[/tex] = p * [tex]f(\frac{1}{q} )[/tex]
[tex]f(\frac{p}{q})[/tex] = [tex]p\frac{k}{q}[/tex]
[tex]f(\frac{p}{q})[/tex] = [tex]k\frac{p}{q}[/tex]
So,
[tex]f(x) = kx[/tex] for all x belongs to Q
Now, as we know that:
Q is dense in R.
So Э x∈ Q' such that Э a seq < [tex]x_{n}[/tex] > belonging to Q such that:

[tex]a_{n}[/tex] belongs to Q,
[tex]a_{n}[/tex] ⇒ [tex]\alpha[/tex]
[tex]f(a_{n} )= ka_{n}[/tex]

Let f is continuous at x=α
This means that:
[tex]f(a_{n} )[/tex] ⇒ [tex]f(\alpha )[/tex]
k [tex]a_{n}[/tex] ⇒ [tex]f(\alpha )[/tex]
k [tex]a_{n}[/tex] ⇒ k [tex]\alpha[/tex]

Which graph shows the solution to the system of linear equations? y = 2x − 2 4x − 2y = 4 Coordinate plane with one line that passes through the points 0 comma negative 2 and 1 comma 0. Coordinate plane with one line that passes through the points 0 comma negative 1 and 1 comma 1 and another line that passes through the points 0 comma negative 2 and 1 comma 0.
This is false, hence, the portion of the graph which does not contain (0, 0) is shaded.
What is inequalities?A connection in mathematics that compares two numbers or other mathematical expressions in an unequal way is known as an inequality. It is most frequently used to compare the sizes of two numbers on the number line. A relationship between two expressions or values that is not equal to each other is known as inequality in mathematics. So inequality emerges from an imbalance.Given the inequalities :
y ≥ 2x + 1
y ≤ 2x - 2
From y ≥ 2x + 1 ;
Since the inequality sign is ≥, a solid line is used to draw the straight line graph of y ≥ 2x + 1
From :
y = mx + c
Where, m = slope ; c = intercept
Hence, a straight line graph with ;
Intercept, c = 1 (where the line crosses the y-intercept)
Slope, m = 2
Consider a point, which isn't on the line ;
Take point (0,0) and use it to test the inequality :
0 ≥ 2(0) + 1
0 ≥ 0 + 1
0 ≥ 1
Since this is untrue, the area of the graph that does not contain (0, 0) is shaded.
From : y ≤ 2x - 2
Since the inequality sign is ≤, a solid line is used to draw the straight line graph of y ≤ 2x - 2
Graph the line y ≤ 2x - 2, with ;
Intercept, c = - 2
Slope = 2
Consider a point, which isn't on the line ;
Take point (0,0) and use it to test the inequality y ≤ 2x - 2:
0 ≤ 2(0) - 2
0 ≤ 0 - 2
0 ≤ - 2
This is untrue, hence the area of the graph that doesn't include (0, 0) is shaded.

If the dimensions of the gym were 24 ft. by 45 ft., how much distance did he save on one lap?
Answer:
18
Step-by-step explanation:
One trip around the gym would be 138 ft.
If we cut the diagonal, we use the Pythagorean theorem to find the distance of the hypotenuse, which is 51 ft.
One trip with the shortcut is 119 ft. (24 + 45 + 51 = 119).
Subtract 119 ft. from 138 feet and you have 18 ft. shorter route than walking the entire perimeter.

given triangle abc prove m∠a=66 2/3
Any triangle's three interior angles add up to 180 degrees, according to the Triangle Sum Theorem.
How do you calculate the triangular sum theorem?Any triangle's three interior angles add up to 180 degrees, according to the Triangle Sum Theorem. m∠1+m∠2+m∠3=180∘.
Here,
According to the triangle sum theorem, a triangle's total angles equal 180°. Therefore, using the Substitution property
=> (3x)° + 90° + (x+10)° = 180°,
=> m(A,B,C) = 180.
To find x, combine similar terms to get
=> 4x + 100 = 180. Then, using the subtraction condition of equality, convert => 13 1/2 to 80.
=> Finally, divide 80 by 5 ( 13 1/2) to find x.
The substitution property may be used to get the measure of the angle A, yielding mA = 5 ( 13 1/2) °.
When the expression is finally simplified, m < A = 66 2/3.

A dilation maps (6, 10) to (3, 5) and the center of dilation is the origin. Given A(12, 4), determine
under the same dilation.
Analyzing the coordinates being provided, the scale factor is found to be 0.5, hence the image of point A(12,4) under the same dilation and the center of dilation as origin is A'(6,2).
What is dilation?A dilation is a transformation in Euclidean space that enlarges or reduces all the points in a figure by a scale factor. In the example given, the dilation maps (6, 10) to (3, 5) with a scale factor of 0.5, and the center of dilation is the origin (0,0). The image of a point A(x,y) under this dilation would be A'(x*0.5, y*0.5). It means the point is scaled down by 0.5 in both x and y coordinate.
How can the dilation described above be used in real-world applications?The dilation described above can be used in real-world applications such as image processing, where it can be used to reduce the size of an image without losing important details, or to enlarge an image without introducing distortion. It can also be used in architectural design to create smaller or larger versions of floor plans and blueprints. Additionally, it can be used in cartography to change the scale of maps without altering the shape of the features on the map.
Analyzing the given dilation map , mapped from (6,10) to (3,5) ,the center of the dilation being origin. We can see that the scaling factor is 0.5.
So , using the same dilation for point A(12,4), The image of A will be,
A'(12*0.5,4*0.5) = A'(6,2)
