By using the partial quotients method 1032/32 = 32 R8.
What is expression?In mathematics, an expression is a combination of numbers, symbols, and operators that represents a mathematical quantity or relationship. It can be a single number, a variable, or a combination of both, and can also include mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. Expressions can be evaluated or simplified using mathematical rules and formulas.
According to the given information:Step 1: Estimate how many times 32 goes into 1032. It's helpful to find a multiple of 32 that is close to 1032. In this case, 32 x 30 = 960, which is less than 1032, and 32 x 31 = 992, which is greater than 1032. So we can estimate that 32 goes into 1032 around 30 to 31 times.
Step 2: Write 30 on top of a division symbol, and multiply 30 by 32. Write the result, 960, under 1032, and subtract.
30
-------
32|1032
960
------
72
Step 3: Write 72 next to the 30 on top of the division symbol. Then, add 72 to the partial quotient (30) to get 102. Write 102 under the partial difference (72) and bring down the next digit, which is 2.
30 72
-------
32|1032

8
step 4: Estimate again how many times 32 goes into the new partial difference, 82. Since 32 x 2 = 64 is less than 82 and 32 x 3 = 96 is greater than 82, we estimate 32 goes into 82 two to three times.
Step 5: Write 2 on top of the division symbol, and multiply 32 by 2. Write the result, 64, under 82, and subtract.
30 72 2
------------
32|1032
960
------
72
64

8
tep 6: Write 2 next to the 30 and 72 on top of the division symbol, and add 2 to the partial quotient to get 32. Write 32 under the partial difference and bring down the next digit, which is 0.
30 72 2
------------
32|1032
960
------
72
64
------
8
0
Step 7: Since there are no more digits to bring down, we have the final answer. The quotient is 32 with a remainder of 8. Therefore, 1032 divided by 32 is equal to 32 with a remainder of 8.
Therefore, by using the partial quotients method 1032/32 = 32 R8 .

Explain about the universe gas law?While dealing with gas, a popular equation was utilized to relate the various components necessary to solve a gas problem. This same Ideal Gas Equation is the name given to this formula. We have always understood that there is no such thing as an ideal. Two well-known presumptions must have been made in this case in advance:
the particles also had no forces acting among them, and these particles do not start taking up any space, implying their atomic volume is entirely ignored.Those four gas variables are: temperature (T), number of gas molecules (n), volume (V), and pressure (P) . Last but not least, the following equation's constant, R, or the gas constant, will be covered in more detail later:
PV = nRT
PV/T = nR
Given data:
absolute temperature 275Kpressure 10 N/ m² volume 0.0224 m³Putting the value;
nR = PV/T
nR = 10*0.0224 / 275
nR = 0.224 / 275
Thus, the formula for the temperature (T), number of gas molecules (n), volume (V), and pressure (P) is found as: nR = 0.224 / 275.

Converging duct flow (Fig. P4–16) is modeled by the steady, two-dimensional velocity field of Prob. 4–16. Is this flow field rotational or irrotational? Show all your work.
V=(u,v)=(U0+bx)i−(by)j
Answers
The flow field is rotational because the curl of the velocity field is non-zero, which is calculated as (-b)k, where k is the unit vector in the z direction.
The velocity field V can be expressed as:
V = (u,v) = (U0+bx)i - (by)j
The flow is rotational if the curl of the velocity field is non-zero, i.e.:
∇ x V ≠ 0
Using the curl operator:
∇ x V = (∂v/∂x - ∂u/∂y)k
where k is the unit vector in the z direction.
Evaluating the partial derivatives:
∂v/∂x = 0, since v does not depend on x
∂u/∂y = -b, since the derivative of by with respect to y is -b
Therefore, the curl of the velocity field is:
∇ x V = (-b)k
Since the curl is non-zero, the flow field is rotational.

What is the role of function in maths?In mathematics, a function is a connection between two sets of numbers in which each member of the first set (known as the domain) corresponds to a single element in the second set (called the range).
In other words, a function takes inputs from one set and produces outputs from another. Inputs are commonly represented by the variable x, whereas outputs are represented by the variable y.
A function can be described using an equation or a graph. The equation y = 2x + 1 represents a linear function in which each value of x yields a distinct value of y.v
a) Because time cannot be negative, the domain of the function g(t) is the set of all non-negative real numbers. As a result, the domain is [0, ].
Because the amount of gas in the tank cannot be negative or more than the tank's capacity. The range of the function g(t) is the set of all non-negative real numbers less than or equal to 23 (the maximum capacity of the tank).
We can graph the function g(t) by plotting points for different values of t and connecting them with a line. For instance, if we pick t = 0, g(0) = 23, we plot the point (0, 23). We plot the point if we select t = 1 and g(1) = 19.8. (1, 19.8).
c) We are informed that there are 6.4 gallons remaining at the end of the journey. As a result, g(t) = 6.4. We can solve for t by plugging this number into the equation for g(t):

Answers
No, we cannot perform element by element addition, subtraction, multiplication and division when the matrices are different sizes, because to do this the size of matrices should be same.
The Element-by-element operations, also called element-wise operations, can only be performed when two matrices have the same dimensions, meaning they have the same number of rows and columns.
In this case, the operations are applied to the corresponding elements of each matrix, resulting in a new matrix with the same dimensions as the original matrices.
When the two matrices have different sizes, element-by-element operations are not defined. In some cases, it may be possible to perform other types of operations, such as matrix multiplication or matrix addition (if the matrices have compatible dimensions).

Simplifying remex's works the same way we simplify fractions. In fractions, a rational number is considered to be a simplified form when its numerator and denominator have no other common factors than 1.
Regular expressions are fractions with variables. In rational expressions, the numerator and denominator are polynomials. That is, it is of the form p(x)/q(x), where q(x) ≠ 0 and p(x) and q(x) are polynomials. Because regular expressions are nothing but fractions, we treat them as if they were fractions.
It is not possible to divide a number by 0. Check what 1/0 is with your calculator, it will return an error. Therefore, no regular expression is defined for variable values with a denominator of 0 (because it is a fraction). For example, in the expression x / (x + 2), the denominator becomes zero when x = -2, so it is called the limit of the rational expression x / (x + 2). In other words, we say x / (x + 2) for all values of x but x ≠ -2.
Simplifying a regular expression means reducing the value of a regular expression to its lowest term or simplified form. Simplifying regexps works the same way we simplify fractions. In fractions, a rational number is considered a simplified form when its numerator and denominator have no other common factors than 1.

What are the zeros of the function f(x)= 240x -2x^2
Answers
Answer:
What are the zeros of the function f(x)= 240x -2x^2
Step-by-step explanation:
To find the zeros of the function f(x) = 240x - 2x^2, we need to set f(x) equal to zero and solve for x:
240x - 2x^2 = 0
We can factor out 2x from the left side:
2x(120 - x) = 0
So either 2x = 0 or 120 - x = 0. Solving for x in each case gives:
2x = 0 => x = 0
120 - x = 0 => x = 120
Therefore, the zeros of the function are x = 0 and x = 120.

Answers
Thus, A’s share is Rs. 2,40,000 and B’s share is Rs. 2,61,000.
What is profit and loss?A profit and loss statement (P&L) is a financial statement that summarizes income, expenses, and expenses incurred during a specified period of time.
Along with the balance sheet and cash flow statement, the income statement is one of the three financial statements issued quarterly and annually by all publicly traded companies.
When used together, the Income Statement, Balance Sheet, and Cash Flow Statement provide detailed insight into the company's overall financial performance.
Accounting is created using the cash method or the accrual method of accounting.
Changes over time are more important than the numbers themselves, so it's important to compare income statements from different accounting periods.
According to our question-
Ratio of their share in profit = Ratio of their investments
Ratio of their share in profit = Ratio of their investments
⇒ 27000 × 5 + 23000 × 15 ∶ 36000 × 9 + 33000 × 6 ∶ 50000 × 6
Thus, ratio of their investments = 480000 ∶ 522000 ∶ 300000 = 480 ∶ 522 ∶ 300 = 80 ∶ 87 ∶ 50
Profit earned after a year = Rs. 6,51,000
A’s share = (80/217) × 651000 = Rs. 240000
B’s share = (87/217) × 651000 = Rs. 261000
Hence, Thus, A’s share is Rs. 2,40,000 and B’s share is Rs. 2,61,000.

Let f(x) = x? - 6x + 8 and g (x) = x - 5.
Find (f + g) (x) and (f - g) (x) .
Answers
(f + g)(x) = x^2 - 5x + 3.
(f - g)(x) = x^2 - 7x + 13
Step by step explanation:
To find (f + g)(x), we add the functions f(x) and g(x) together:
(f + g)(x) = f(x) + g(x) = (x^2 - 6x + 8) + (x - 5)
Combining like terms, we get:
(f + g)(x) = x^2 - 5x + 3
Therefore, (f + g)(x) = x^2 - 5x + 3.
To find (f - g)(x), we subtract the function g(x) from f(x):
(f - g)(x) = f(x) - g(x) = (x^2 - 6x + 8) - (x - 5)
Again, combining like terms, we get:
(f - g)(x) = x^2 - 7x + 13
Therefore, (f - g)(x) = x^2 - 7x + 13.

Answers
Answer:
1/6
Step-by-step explanation:
5/6 - 4/6 = 1/6
Answer:
Step-by-step explanation:
To subtract these fractions, we need to have a common denominator. In this case, the denominators 5 and 6 do not match, so we have to find the least common multiple (LCM) of 5 and 6, which is 30.
Then, we can convert both fractions so that they have a denominator of 30:
5/6 = 25/30
4/6 = 20/30
Now we can subtract the numerators:
25/30 - 20/30 = 5/30
Simplifying the result to its lowest terms, we have:
5/30 = 1/6
Therefore, 5/6 - 4/6 = 1/6.

Now, we can consider the remainders when p is divided by each of the answer choices:
F. 7: If p = 7, then p³- p = 7³ - 7 = 342, which is not divisible by 7.
G. 5: If p = 5, then p³ - p = 5³ - 5 = 120, which is divisible by 5.
H. 4: If p = 4, then p³ - p = 4³ - 4 = 60, which is divisible by 4.
J. 3: If p = 3, then p³ - p = 3³ - 3 = 24, which is divisible by 3.
Therefore, we can see that p(p + 1)(p − 1) is not always divisible by 7, but it is always divisible by 5, 4, and 3.
Thus, the correct answer is (G) 5.

Answer:
Scale factor = 2.25
Step-by-step explanation:
To find the scale factor between two similar shapes, we need to compare the corresponding sides of the shapes.
The scale factor is the ratio of the length of any side of one shape to the length of the corresponding side on the other shape.
From inspection of the given diagram, the ratio of the corresponding sides of the two similar figures is:
⇒ Figure 1 : Figure 2 = 8 : 18
Therefore, to find the scale factor from Figure 1 to Figure 2, divide the side length of Figure 2 by the corresponding side length of Figure 1:
[tex]\implies \sf Scale\;factor=\dfrac{18}{8}=2.25[/tex]
show that if 16 people are seated in a row of 20 chairs, then some group of 4 consecutive chairs must be occupied.
Answers
The process to show that if 16 people are seated in a row of 20 chairs, then some group of 4 consecutive chairs must be occupied is shown below.
We prove this using the Pigeonhole Principle, which states that if n items are placed into m containers, and n > m, then at least one container must contain more than one item.
Let us consider the 16 people seated in a row of 20 chairs. Each person occupies one chair, so there are 20 - 16 = 4 empty chairs in the row.
We assume that empty chairs as containers, and people as items that need to be placed into containers.
Since there are more items (people) than containers (empty chairs), there must be at least one group of 2 or more consecutive empty chairs.
Now, let's consider the complement of this statement: Suppose there are no groups of 4 consecutive chairs that are occupied. Then, each group of 4 consecutive chairs contains at most 3 people.
We partition the row of chairs into groups of 4 consecutive chairs.
So, there are 20 - 3 = 17 such groups. By the statement above, each of these groups contains at most 3 people. Therefore, the total number of people seated in the row is at most 17×3 = 51.
But, we know that there are actually 16 people seated in the row. This is a contradiction, since 51 < 16. Therefore, our assumption that there are no groups of 4 consecutive chairs that are occupied must be false, and we have proved that some group of 4 consecutive chairs must be occupied.

A invested Rs 4500 for 3 years at the rate of 8% annual compound interest and B invested the
same amount for same time at the rate of per month per rupee I paisa simple interest. Calculate
(i) The interest received by A. (ii) The interest received by B.
Answers
The calculation of the interest received by Investor A and Investor B is as follows:
Investor A = $1,168.70 (Compound)Investor B = $1,620 (Simple).What is the difference between compound and simple interest?Compound interest is based on the system of charging interest on accumulated interest and principal for each period.
Simple interest is charged on only the principal for each period.
A's Investment at 8% Annual Compound Interest:N (# of periods) = 3 years
I/Y (Interest per year) = 8%
PV (Present Value) = $4,500
PMT (Periodic Payment) = $0
Results:
Future Value (FV) = $5,668.70
Total Interest = $1,168.70
B's Investment at Paisa 1 per R1.00 Monthly Simple Interest:N (# of periods) = 3 years
r = 1 paisa per rupee per month
= 1÷100*100 = 1%
Annually rate =1%*12 = 12%
PV (Present Value) = $4,500
Results:
Total Interest = $1,620 (R4,500 x 12% x 3)
Future Value (FV) = $6,120.
Thus, while Investor A receives $1,168.70 at the end of 3 years, Investor B receives $1,620.

Find the mass of the solid bounded by the xy-plane, yz-plane, xz-plane, and the plane (x/2)+(y/3)+(z/6)=1, if the density of the solid is given by δ(x,y,z)=x+4y.
mass=?
Answers
The mass of the solid is approximately 17.333 units.
To find the mass of the solid bounded by the given planes, we need to integrate the density function δ(x,y,z) over the volume of the solid. We can express the volume of the solid as the region enclosed by the planes
0 ≤ x ≤ 2, 0 ≤ y ≤ 3, 0 ≤ z ≤ 6-3x-2y
So, the mass of the solid is given by the triple integral
M = ∭ δ(x,y,z) dV
= ∫₀² ∫₀³ ∫₀^(6-3x-2y) (x+4y) dz dy dx
= ∫₀² ∫₀³ [(x+4y)(6-3x-2y)] dy dx
= ∫₀² [(6x-3x²)⁄2 + 8xy - 4y²] dy
= ∫₀² [(6x-3x²)⁄2 + 12x - 36] dx
= [3x³/2 - x⁴/4 + 6x² - 36x]₀²
= (12 - 8/3 + 24 - 72) - (0 - 0 + 0 - 0)
= 17.333 units

Answers
The largest interval which includes x=0 for which the given initial value problem has a unique solution is (-∞,4).
The Differential Equation is : (x-4)y'' + 2y = x,
Now, we convert the differential-equation into the standard form,
We get,
⇒ y'' + 2y/(x-4) = x/(x-4) ...equation(1)
We know that second order differential-equation is :
⇒ ay'' + by' + cy = R ...equation(2),
Now, On comparing equation(2) with equation(1),
we get,
The values are : a = 1, b = 0 and c = 2/(x-4), R = x/(x-4),
The Values of "c" , "R" are continuous except at the value "4" because on substituting 4 in x of c and x of R the values of c and R approaches to ∞.

f the determinant of a matrix is , and the matrix is obtained from by swapping the third and fourth columns, then
Answers
If the determinant of a 5 times 5 matrix A, swapping two columns in a matrix changes the sign of the determinant. Thus, det(C) = -det(A) = -(9) = -9. Determinant of a 4 times 4 matrix A is det (A) = 6, multiplying a column of a matrix by a scalar k multiplies the determinant by k. Thus, det(B) = 5det(A) = 5(6) = 30.
To evaluate det(C) given that det(A) = 9 and C is obtained by swapping the third and fourth columns of A, we can use the fact that swapping two columns of a matrix multiplies its determinant by -1. Thus, det(C) = -det(A) = -9.
To evaluate det(B) given that det(A) = 6 and B is obtained by multiplying the second column of A by 5, we can use the fact that multiplying a column of a matrix by a scalar multiplies its determinant by that scalar. Thus, det(B) = 5(det(A)) = 5(6) = 30.
