Determine the y-intercept of the line
11x - 8y = 22

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 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

now, integral becomes

       2 ∫¹₀ (1- r²) r dr dФ

= 4[tex]\pi[/tex] ( r²/2 - r⁴ /4)¹ ₀

= 4[tex]\pi[/tex] ( 1/2 - 1/4)

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,

1 dollar ($) = 100 cents

Multiply both sides by 26.75

Answer:

Step-by-step explanation:

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

(1) The explicit formula and the 21st term for the first sequence are:

aₙ = 10 - 5n and a₂₁ = -95

(2) The explicit formula and the 21st term for the second  sequence are:

aₙ = 1.5n + 1.5 and a₂₁ = 33

A sequence in which the difference between any two consecutive terms is the same is known as an arithmetic sequence.

(1)

The given sequence is 5, 0, -5, -10,...

Note the difference between two consecutive terms of the sequence is the same, which is -5.

Therefore, the sequence is an arithmetic sequence with a common difference of d = -5.

The [tex]n^{th}[/tex] term of an arithmetic sequence is given by:

aₙ = a₁ + (n-1)d

Substitute a₁ = 5 and d= -5 into the equation,

aₙ = 5+ (n-1)(-5)

   = 5 - 5n + 5

aₙ = 10 - 5n

To find the 21st term, substitute n = 21 into the above equation,

a₂₁ = 10 - 5n

a₂₁ = 10 - 5(21)

a₂₁ = 10 - 105

a₂₁ = -95

Hence, the explicit formula and the 21st term for the first sequence are:

aₙ = 10 - 5n and a₂₁ = -95

(2)

The given sequence is 3, 4.5, 6, 7.5, 9,...

Note that the difference between two consecutive terms is 1.5, therefore, the sequence is an arithmetic sequence with a common difference of

d = 1.5.

The [tex]n^{th}[/tex] term of an arithmetic sequence is given by:

aₙ = a₁ + (n-1)d

Substitute a₁ = 3 and d= 1.5 into the equation,

aₙ = 3 + (n-1)1.5

aₙ = 3+1.5n-1.5

aₙ = 1.5n+1.5

To find the 21st term, substitute n = 21 into the above equation,

a₂₁ = 1.5(21) + 1.5

a₂₁ = 31.5 + 1.5

a₂₁ = 33

Hence, the explicit formula and the 21st term for the second  sequence are:

Using inequality the number of 105  of 120-kilogram crates that can be loaded into the shipping container.

What is inequality?

A difference between two values indicates whether one is smaller, larger, or simply not equal to the other. In mathematics, the term "inequality" refers to a relationship between two expressions or values that is not equal to one another.

The greatest weight that container can hold = 27500

Shipment weight already  in the container =14900

Amount of weight that may be loaded = 27500 - 14900 = 12600

Weight of each crates = 120 kg

Let x be the maximum number of 120 kg crates that can be loaded to the container then,

Weight of 'x' number of 120 kg crates = 120x

Therefore, the required inequality is as follows

=>120x< 12600

(since the maximum amount of weight of crates that can be put in the container should be less than or equal to the total weight of the maximum number of crates that can be loaded into the container).

Then the inequality is ,

=> x [tex]\leq \frac{12600}{120}[/tex]

=> x ≤ 105.

Thus, a maximum of 105 crates can be loaded into the container.

What is the arithmetic operation?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. 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

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).
