Step-by-step explanation:

We can see from the provided data that it is obviously divergent.

Convergent sequence occurs when, as n approaches infinity, you arrive at a final as well as constant term through a number of terms. Divergent sequences are those in which individual terms never stabilize; instead, they constantly grow or decrease as n approaches infinity, approaching either infinity or -infinity.

A series diverges when it moves up, down, to infinity or minus infinity without settling on a value.

The series' parts are becoming larger and larger while being interrupted by some constant "1" (however they are useless in this situation since the series is divergent because there are always two numbers that follow an intercepting "1" that are greater by 1 than the two that came before it).

The value of y'' at the point where x = 0 is 8.

A derivative is a mathematical concept that measures how much a function changes as its input (or independent variable) changes. It is often represented by the symbol "dy/dx" or "f'(x)", and is used to calculate the slope of a function at a particular point.

To find the value of y'' at the point where x = 0, we first take the derivative of the equation with respect to x. This gives us y' + 8exy' = 0. Then, we take the derivative of this equation with respect to x again, which gives us y'' + 8exy'' + 8ey' = 0. Substituting x = 0 into this equation gives us y'' + 0 + 8e(0) = 0, which simplifies to y'' = 8.

As an outcome, an isosceles triangle has two equal sides as well as two equal angles. As from Greek words iso (same) and skelos, the phrase is formed (leg). Except for a right triangle, which has quadrilateral on all sides, a scalene triangle lacks equal sides on each side.

The slope of the line connecting the bottom right vertex of something like the triangle to the top left vertex of both the square is equal to -1/2.

This line's equation is y = (-1/2)x + 10. (1)

The point at the triangle's top vertex is (15, 10)

The slope of the segment between (10, 0) and (15, 10) is 10/5, which equals two.

The line connecting these two locations has the equation y = 2(x - 10) y = 2x - 20. (2)

You may get the x coordinate of the point where these lines cross by putting (1) = (2) 

(-1/2)x + 10 = 2x - 20 

30 = [5/2]. x x equals 12 and y equals 2(12) - 20 = 4.

Therefore, the triangle's shaded area's height is 4 and its base is 10.

Its area is therefore (1/2)(4)(10) = 20 units squared.

The dimensions of the rectangular field with a minimum cost are x = 50 m and y = 2 m.

Let x be the length of the north-south sides and y be the length of the east-west sides.

The area will be given by: A = xy

The cost will be given by: C = 20x + 5y

We have to find the dimensions (x and y) that minimize the cost C subject to the constraint that the area A is 100 m2.

Using the constraint, we have:

A = xy = 100

We can solve this equation for one of the variables in terms of the other, say x in terms of y.

We get: x = 100/y

Substituting this into the cost equation, we get:

C = 20(100/y) + 5y

Differentiating this equation with respect to y and equating it to 0, we get:

dC/dy = 20/y2 - 5 = 0

or, y2 = 4

or, y = ±2

We choose the positive value for y, so y = 2

Substituting this value of y in the equation for x, we get:

x = 100/2 = 50

Therefore, the dimensions of the rectangular field with a minimum cost are x = 50 m and y = 2 m.

Answer:

y = 136

x=15

Step-by-step explanation:

to work this question out you must know the angles on a straight line add up to 180 degrees. By doing that we can find the top angle inside of the triangle.

180 - 104 = 76

to find x we need to know that angles in a triangle add up to 180 degrees.

180 =  (3x-1) + 4x + 76

To solve for x, we can first simplify the equation.

180 = (3x-1) + 4x + 76

This can be re-arranged as:

(3x-1) + 4x = 104

and then combined as:

7x = 105

Finally, we can solve for x by dividing both sides by 7:

x = 105/7

x = 15

So the value of x that satisfies the equation is 15

to find y we need to know that angles on a line equal 180

180 = (3(15)-1) + y

180 = 44 + y

To find the value of y, we can subtract 44 from both sides

y = 180-44

y = 136

The Hindu-Arabic numeral system is superior to other numeral systems because of its invention of the number 0. This allows for the representation of the concept of nothingness or absence, which allows for the development of more advanced mathematical operations such as negative numbers and decimal fractions.

The two purposes of numerals or digits are to show the cardinal value (how many) and to show the place value (10s, 100s, 1000s). The cardinal value is the actual quantity of a number, while the place value is the position of a digit in a number, which determines its value in relation to other digits.

The natural numbers are the numbers used in a counting process and do not include 0. They include the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and so on to infinity. The principle of closure is the idea that certain operations, such as addition and multiplication, will always result in a natural number when performed on natural numbers. However, subtraction and division do not result in natural numbers in all cases.

Integers are positive and negative numbers that start at 0 and expand infinitely in both directions. They are closed under addition, multiplication, and subtraction. However, division is not closed under integers.

Rational numbers are numbers that can be expressed as the quotient of two integers. Irrational numbers are non-terminating, non-repeating decimals.

The three axioms of equality are the reflexive property (A = A), the symmetric property (if A = B, then B = A), and the transitive property (if A = B and B = C, then A = C).

The commutative property states that the order of the numbers does not affect the result in operations such as addition and multiplication. The associative property states that the grouping of numbers does not affect the result in operations such as addition and multiplication. The distributive property states that multiplication can be distributed over addition.

The unity element for multiplication is the number 1, which serves as the identity element for multiplication. The zero element for addition is 0, which serves as the identity element for addition. Dividing by 0 is an error and not allowed.

What is equation of the circle?

A closed curve that is drawn from a set point known as the center and has all of its points at exactly the same distances from it is termed a circle. The formula for a circle with the coordinates (h, k) in its center and radius is [tex](x-h)^2+(y-k)^2=r^2[/tex]

This represents the equation's conventional form. As a result, the equation for the circle is simple to find if we also know the coordinates for the radius of the circle.

Here according to the graph the center of the circle is (2,-1) and radius of the circle = 2+2=4 unit.

Now using circle equation then

=> [tex](x-p)^2+(y-q)^2=r^2[/tex]

Where p=2 , q=-1 and r=4 then
