Lines a, b, and c are parallel, and d and e are also parallel to each other.

No matter how far they may reach in either direction, parallel lines are ones that are equidistant from one another and never cross. Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline. In this essay, let's study more about parallel lines.

Given the 5 lines and the angles made by them,

if ∠1 = ∠3 then a║b Because they intersect on the same line.

if ∠4 = ∠6 then c║b Because they intersect on the same line.

if ∠1 = ∠7, ∠2 = ∠8,  ∠23 = ∠5, ∠11 = ∠17, ∠2 = ∠8, ∠24 = ∠18, ∠6 = ∠12, and some more than d║e Because they intersect on the same line.

Therefore from the above figure, if two lines intersect another line with the same angle then they are parallel lines.

The expression after simplifying with the first rule of radicals is 9√5.

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is side²

We have,

Area of a square = side² _______(1)

Area = 405 square feet _______(2)

From (1) and (2) we get,

405 square feet = Side²

Side = √405 feet

[ 405 = 81 x 5 ]

Answer:

y = -5x -2

Step-by-step explanation:

Equation y=mx+b

Slope m=(y2-y1)/(x2-x1)

Slope m=(-7- -2)/(1 - 0)

Slope m=(-7 + 2)/(1 - 0)

Slope m=(-5)/(1)

Slope m= -5

Point-slope form = y − y 1 = m ( x − x 1 )

Point-slope form = y − -2 = -5 ( x − 0 )

Point-slope form = y + 2 = -5x − 0

Therefore the solution to the given question equation will shift the graph of the original equation up 2 units in  y=2x + 9

equation, a declaration of equivalence between two expressions with variable- and/or number-filled expressions. In essence, equations are questions, and efforts to discover a method for answering them have fueled the growth of mathematics. Equations range in complexity from straightforward addition-and-multiplication equations in mathematics through differential equations, exponential equations that use exponential expressions, and integral equations.

Here,

It follows a linear function. y=mx + b

If A is the location where the y-axis intersects, then x = 0 and y = b are the coordinates of A.

In order to move the graph up by 2 units, you must add 2 units to b.

In our case, b was originally equal to 7, so shifting it up makes b become 7+2=9, and the new function is y=2x + 9.

Because the value of x is 126° and the value of cos 2x is -0.301, which is fractionally identical to -7/25, the value of cos 2x will be -7/25.

Trigonometry is the study of angles and the angular relationships between planar and three-dimensional shapes. The cosecant, cosine, cotangent, secant, sine, and tangent are among the trigonometric functions (also known as the circle functions) that make up trigonometry. The sine, cosine, and tangent are the three fundamental trigonometric operations. The cotangent, secant, and cosecant functions are derived from these three basic functions. On these functions, all trigonometrical concepts are built.

Here,

sin x=4/5

x=126°

Cos 126°=-0.588

cos (2*126)=-0.310

The value of cos 2x will be -7/25 because value of x is 126° and that of cos 2x is -0.301 that is fractionally equal to -7/25.

Answer: 3150 is the answer

Step-by-step explanation:

To find the value of K, we need to find the point at which the line Y=2x+K is tangent to the parabola Y=x^2-4x+4. This means that the line and the parabola will have the same y-value at this point, and the line will be tangent to the parabola (meaning it will just touch the parabola at this point, without intersecting it).

To find the point at which the line and parabola are tangent, we can set Y=2x+K equal to Y=x^2-4x+4 and solve for x:

2x + K = x^2 - 4x + 4

x^2 - 4x + 4 - 2x - K = 0

(x-2)^2 = K

x = 2 +/- sqrt(K)

Since the line is tangent to the parabola, it will just touch the parabola at this point, which means that the parabola will have a minimum value at this point. This means that the value of K must be nonnegative, because the square root of a negative number is not a real number. Therefore, K must be equal to or greater than 0.

So, the value of K for which Y=2x+K is tangent to Y=x^2-4x+4 is K >= 0.

The probability that the first household speaks French, but the second household speaks English, is 0.1449. The correct option is a.

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

In Canada, 63% of households speak English as their primary language, and 23% speak French as their primary language.

Let A be the event that the household speaks French and B be the event that the household speaks English.

Converting percentage to decimals,

63% = 0.63

and 23% = 0.23

According to the question,

P (A) = 0.23 and P (B) = 0.63.

Then, the probability that the first household speaks French, but the second household speaks English is,

Probability =(0.23) x (0.63)

                  =0.1449

Therefore, the probability that the first household speaks French, but the second household speaks English is 0.1449.

It will take the sales of 381 necklaces to reach break-even.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

An equation is an expression that shows the relationship between two or more numbers and variables.

We are given that Tony invest an initial amount of $381 for advertising, and materials cost $8 for each necklace he makes. Tony can sell his creations for $9 per necklace.

Let the number of necklace be x then;

8x + 381 = 9x

Solving;

9x - 8x = 381

x = 381

Therefore, Total expenses = 8x + 381

8(381) + 381

Answer:

6 drinks

2 boxes of candy

==================================================

Explanation:

x = number of drinks

y = number of boxes of candy

These two variables represent positive integers.

"He bought 3 times as many drinks as candies" which means we can set up the equation x = 3y

-------------

1 drink costs $4.50

x drinks cost 4.50x dollars

1 box of candy costs $3

y boxes of candy cost 3y dollars.

4.50x + 3y = total cost = 33 dollars

Therefore, we arrive at the second equation of 4.50x+3y = 33

-------------

We have this system of equations

[tex]\begin{cases}x = 3y\\4.50x+3y = 33\end{cases}[/tex]

I'll use substitution to solve. Replace x with 3y in the second equation, then isolate y.

[tex]4.50x+3y = 33\\\\4.50(3y)+3y = 33\\\\13.50y+3y = 33\\\\16.50y = 33\\\\y = 33/16.50\\\\y = 2\\\\[/tex]

This tells us he bought 2 boxes of candy.

Use that value to find x.

[tex]x = 3y\\\\x = 3*2\\\\x = 6\\\\[/tex]

Carter also bought 6 drinks.

Increasing the given sample size will decreases the probability because σx will decreases as n value increases.

In Statistitics whenever we test a hypothesis for testing a statistic, we use confidence interval. Confidence interval is on either side of an assumed value a margin of error. Margin of error is calculated as critical value * sigma/sqrt of n. Thus we find that whenever n increases, margin of error decreases.

Thus making confidence interval narrower and thus making probability for accepting null hypothesis a less value. As the pattern sizes increase, the range of every sampling distribution decreases so they emerge as more and more leptokurtic. The variety of the sampling distribution is smaller than the variety of the authentic populace. Therefore, as a pattern length increases, the pattern imply and general deviation might be nearer in fee to the populace imply μ and general deviation σ.
