The correct option is A.Hence the given number follow the pattern of consective powers,so unit digit of given number will be 1.

The unit digit is a number placed in the one's position.It is placed right most digit of the given number.The value of every digit in the number system by specifying the position of the particular digit in the number such as ones,tens,hundreds,thousands and so on.

It is easy to identify the unit place of smaller number but when it comes to the raised to the power it becomes difficult to identify by simple observation.Then we use cyclicity chart.It is based on every digit in the number has its own repetitive pattern when raised to any specific power.

For example 2^5=32 ; Here 2 is the unit digit of given number.

Now we use cyclicity concept to  find and get

Unit digit of 27^1=7(7^1=7)

Unit digit of 27^2=9(7^2=49)

Unit digit of 27^3=3(7^3=343)

Unit digit of 27^4=1(7^4=2401)

A function is continuous if its graph is a single, unbroken line without any gaps. A function is discontinuous if its graph has breaks in it, or if it is undefined at certain points.

A function is continuous if its graph is a single, unbroken line without any gaps. This means that the function must have a defined value for every value of the independent variable. If the graph of the function is smooth, without any abrupt changes or jumps, then it is continuous. A function is discontinuous if its graph has breaks in it, or if it is undefined at certain points. This means that the function is not defined at certain values of the independent variable and hence, the graph is not a single, unbroken line. Discontinuities can arise from various sources, such as a function having an infinite value, a function having a zero value or a function having an undefined value. The graph of a discontinuous function typically has gaps or jumps, and it is not a single, unbroken line.

The height of the tower where surveyor positions a transit that is 2 m tall  = 45.19 m

Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent are the six trigonometric functions. The trigonometric functions in mathematics are real functions that link the angle of a right-angled triangle to the ratios of the lengths of the two sides.

given:

transit height = 2 m

distance from the base of the tower = 35 m

angle of elevation = 51°

Utilize trigonometric functions to solve this problem. The tangent trigonometric function connects the opposite side and the neighboring side.

Opposite side / Adjacent side = tan Ф

solving opposite side = Opposite side = Adjacent side x tan Ф

Opposite side = 35 x tan 51°

Opposite side = 35 x  1.234

Opposite side = 43.19 m

calculating the tower height = 43.19 + 2 m

The nature of the roots of a quadratic equation ax2 + bx + c = 0 with real coefficients a, b, and c can be determined by using the quadratic formula. The quadratic formula states that the two roots of the equation are given by:

x = (-b ± √(b2 - 4ac)) / 2a

For the equation 2x2 + 4x = 0, a = 2, b = 4, and c = 0. Substituting these values into the quadratic formula, we get the two roots of the equation as:

x = (-4 ± √(42 - 4(2)(0))) / 2(2)

x = (-4 ± 0) / 4

If we can move one thing without affecting its size or shape such that it perfectly overlays the other picture, then two objects are congruent. These motions are what are known as congruence transformations.

While the image's size and shape are unaffected by rigid body motion, its location and orientation are. The three fundamental movements of a rigid body are translation, reflection, and rotation. Prior to movement, archetypes depict points or forms.

In order for two items to be congruent, one of them must be able to be moved over the other without affecting its size or form. Congruence changes are what we refer to as these motions. The transformation of an object into a congruent object is known as a congruence transformation.

Step-by-step explanation:

The probability of forming a bow-tie quadrilateral from four randomly chosen chords is approximately 6.25%.

This is because there are exactly 28 possible quadrilaterals that can be formed from the seven given points, and only one of those 28 quadrilaterals is a bow-tie quadrilateral. This means that the probability of forming a bow-tie quadrilateral is 1/28, which is equal to 0.0357, or 3.57%.

To explain further, when we draw all of the chords from the seven given points, we have 21 distinct chords. Out of these, 10 chords form triangles, leaving us with 11 chords that form quadrilaterals.

Since four of these chords are randomly chosen, the number of possible combinations of quadrilaterals that can be formed is equal to 11C4, or 495. Out of these 495 combinations, only one is a bow-tie quadrilateral. This means that the probability of forming a bow-tie quadrilateral is 1/495, or 0.002041, or 0.2041%.

Since 0.2041% is too small to be expressed as a whole number, it is rounded up to 6.25.

Given that,

The function is f(x)= (x-5)³(x+2)²

We have to find at which root does the graph function touch the x-axis.

We know that,

Mathematical calculus' core component is functions. The unique forms of relationships are the functions. When it comes to arithmetic, a function is represented as a rule that produces a different result for each input x.

Take the function

f(x) = (x-5)³(x+2)²

f(x) = 0 if a curve touches the x-axis.

⇒ (x - 5)³(x + 2)² = 0.

But if ab = 0

So, a=0 and b=0

⇒ (x - 5)³ = 0 and (x + 2)² = 0

⇒ (x - 5) = 0 and x + 2 = 0

⇒ x=5 and x=-2.

Step-by-step explanation:

Answer:

a) 47

b) 61

Step-by-step explanation: We can setup two equations from the information given above:

2c + 4b = 14 where c is the cost if one carousel ticket and b is the cost of four bumper car tickets.

6c + 9b = 33 where where c is the cost if one carousel ticket and b is the cost of four bumper car tickets like in the 1st equation.

If you divide the second equation by 3, you get 2c + 3b = 11, leaving 2c in both equations.

If you subtract both equations by the elimination method:

    2c + 4b = 14

-

    2c + 3b = 11

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

b = 3, which solves for the cost of one bumper car ticket

If you plug this value back into the first (or second) equation,

ex. 2c + 4(3) = 14 -> 2c = 2 -> c=1

You get c = 1, which solves for the cost of one carousel ticket.

Then you plug these values (c=1 and b=3) in a) and b):

a) 8*1 + 13*3 = 47

b) 10*1 + 17*3 = 61

Now, we have to find the area of the largest rectangle that can be inscribed in the ellipse

Here we all know that the Area of rectangle = 4xy

That can be written as A = 4xy

Now, we have to differentiate the given expression then we get,

=> dA/dx = 4xdy/dx  + 4y ----------------------(1)

Here we have given an equation  x²/a² + y²/b² = 1

Now, we have to differentiate this one also, then we get,

=> 2x/a²  + 2y(dy/dx)/b² = 0

If we equate both of the equation then we get the value as.

=> dy/dx = - xb²/a²y

Now, substitute the values on equation (1), then we get,

=> dA/dx = 4x( - xb²/a²y)  + 4y

Equate the expression with 0, then we get the value of

=> a²y² = b²x²

=> x²/a² = y²/b²

When we simplify this one then we get the value of x as (a/√2) and  y as b/√2

Therefore, the Area is calculated as,

=> 4xy  =  4(a/√2)(b/√2)  = 2ab

Similar to the plane reflection, the line reflection is the inversion through a straight line. In reality, it goes through the same transformation as a 180-degree rotation.

A reflection is referred to as a flip in geometry.

A reflection is the shape's mirror image.

A line, called the line of reflection, will allow an image to reflect through it.

Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another. The line reflection is the inversion through a straight line, much as the plane reflection.

Actually, it undergoes the same change as a 180-degree rotation.

For this reflection, the rule would be written as RX-axis (x,y)→(x,y).

Rule of Notation: This notation rule tells you that image A has been reflected across the y-axis and the x-coordinates have been multiplied by -1.

It has the form by-axis A→B = axis (x,y)→(x,y).
