The value of x₃ , starting with x₁ = 8 is 4.578
Given in the question ,
The iterative formula for the sequence is
=> xₙ₊₁ = 5 - 2 / xₙ
Also , x₁ = 8
Putting n = 2 in iterative formula
x₂ = 5 - 2 / x₁
Substituting the value of x₁
=> x₂ = 5 - 2 / 8
=> x₂ = 5 - 1 / 4
=> x₂ = (20 - 1)/4
=> x₂ = 19/4
=> x₂ = 4.75
Now , putting n = 3
x₃ = 5 - 2 / x₂
Substituting the value of x₂
=> x₃ = 5 - 2 / x₂
=> x₃ = 5 - 2 / 4.75
=> x₃ = 5 - 0.421
=> x₃ = 4.578

The integral Value is [tex]\pi[/tex] or 22/7 or 3.14
Integral Value: It is a value which is obtained after integrating.
Triple Integral: Integral function of a three variable over a region in R³ ( real number 3D space) are called triple integral.
For x = 2,
x = 2y² + 2z²
equating those two functions, we get,
1 = y² + z²
that gives -1≤ y≤ 1 and -(√x/2 -y²) ≤ z≤ (√x/2 - z²) and 2y²≤ x ≤ 2
so after the integration, the form is quite complicated to solve so use the following form instead letting x = 2 and x = 2y² + 2x², so that the integral became
∫∫∫ 2y² + 2z² dx dA which becomes
ff (2 - 2y² - 2z²) da now use polar coordinate where y= 1 cos Ф and z = 1 sinФ

To Calculate the size of angle x.
What is a right angle triangle?
A right angle triangle has one of its angles as 90 degrees. Therefore, the sides of the triangle can be found using trigonometric ratios.
area of a triangle = 1 / 2 bh
where
b = base of triangle
h = height of triangle
Hence,
area of a triangle = 1 / 2 × 4 × h
24 = 2h
h = 24 / 2
h = 12 cm
DC = 24 - 4 = 20 cm
AC = 12 cm
tan x = opposite / adjacent
tan x = 12 / 20
x = tan ⁻¹ 0.6
x = 38.06
x = 38.06 degrees.
Hence the answer is the measure of the angle x in the right triangle ABD is 38.06 degrees.

The number of laddus who were there at the beginning Rohan has is 48.
Here we have to find the number of laddu Rohan at the beginning.
Let x be the number of laddu Rohan have.
He gave on the first day = x × 1/3= x/3
The leftover laddu = x - x/3
= 2x/3
Laddu is given on the second day = 2x/3 × 1/4
= x/6
Here we know that the laddu given by Rohan is 8,
So
x/6 = 8
x = 48

4x-y=5 slope n y intercept
Step-by-step explanation:
4x - y = 5
You need to convert this equation to point intercept form: y = mx + b where m = slope and b = y-intercept.
4x - y = 5
subtract 4x from both sides:
4x - y - 4x = 5 - 4x
-y = 5 - 4x
divide both sides by -1:
(-y)/-1 = (5 - 4x)/-1
y = -5 + 4x
rearrange right side:
y = 4x - 5
Remembering that: y = mx + b where m = slope and b = y-intercept
slope = 4
y-intercept = -5 or (0 , -5)

The volume of a right cone is 245ππ units33. If its height is 15 units, find its radius.
The volume of the right cone is 7 units.
How to find the radius of a cone with volume?The radius of a cone can be found as follows:
The volume of the right cone is 245π unit³. The height of the right cone is 15 units.
Therefore,
volume of a right cone = 1 / 3 πr²h
where
r = radiush = heightHence,
volume of the right cone = 245π
h = 15 units
Hence,
245π = 1 / 3 × π × r² × 15
divide both sides by π
245 = 15 / 3 r²

Find the distance between the two points in simplest radical form.
(7,1) and (4,5)
The distance between the two points in simplest radical form is 5.
What is meant by distance between two points?The length of the line segment connecting two points in a plane is the distance between them. The formula for calculating the distance between two places is typically d=((x₂ - x₁)² + (y₂ - y₁)²). This formula is used to calculate the distance between two locations on a coordinate plane or the x-y plane.
In geometry, distances are usually positive unless the points coincide. Consider two points A(a, b) and B to obtain the formula for the distance between two points in the plane (c, d).
The linear distance between two points is equal to the square root of the sum of the squared x-axis and y-axis distances. To continue with the example, the distance between (3,2) and (7,8) is sqrt (52), or 7.21 units.
Given,

Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.
To calculate the size of town A in 1990, multiply the current population by 2000 + (200x40) and add 40 years to account for population growth.
To work out how big town B will be in 1990
We have to use the equation 2000 X 1.1^40 because to work out plus 10 percent you need to do 1.1 and do it to the power of 40 for how many years
So 2000* 45.259 = 90518. for 2000people of A Town
And 200* 45.259 = 9051.8 for 200people of B Town

What is the nearest cent?
The total cost to the nearest cent = 2675 cents.
Given that:
The cost of backpack = $25
Tax = 7%
To calculate the total cost, we can also approach the problem in two ways:
1). Multiply the amount by 7% ($25 x 0.07 = $1.75, rounded up to the nearest cent at 175 cents or $1.75). This will tell us how much tax we will have to pay. Add this to the cost to get the total amount one has to pay (25 + 1.75 = $26.75 or 2675 cents).
2). Multiply the amount by 107%. This includes both steps from 1 in one step. ($25 x 1.07 = $26.75; $26.75 rounded to dollars).
We know that,

let's multiply both sides by -4, and the result is
