Consider a rectangular box with dimensions length (L), width (W), and height (H).The method of Lagrange multipliers can be used to find the maximum volume of a rectangular box with its diagonal length fixed at l.

Consider a rectangular box with dimensions length (L), width (W), and height (H). We want to maximize the volume of the box, V = LWH, subject to the constraint that the diagonal length is fixed at l.

To apply the method of Lagrange multipliers, we introduce a Lagrange multiplier λ and form the following function:

F(L, W, H, λ) = LWH + λ(D² - L² - W² - H²),

where D is the fixed diagonal length, and the term λ(D² - L² - W² - H²) is the constraint equation.

We then take partial derivatives of F with respect to L, W, H, and λ, and set them equal to zero to find critical points. Solving these equations, we obtain:

∂F/∂L = WH - 2λL = 0,

∂F/∂W = LH - 2λW = 0,

∂F/∂H = LW - 2λH = 0,

∂F/∂λ = D² - L² - W² - H² = 0.From equations (1)-(3), we find that WH = 2λL, LH = 2λW, and LW = 2λH. Dividing these equations, we get (WH)/(LW) = L/H, (LH)/(LW) = W/H, and (LW)/(LH) = W/L. Simplifying, we have L = W = H, which means the dimensions of the box are all equal.

Substituting L = W = H into equation (4), we have 3L² = D², or L = W = H = D/√3.

Therefore, the maximum volume of the rectangular box is                        (D/√3)³ = D³/√27.

Answer: 32

Step-by-step explanation:

This is an example of an arithmetic sequence as the difference between the first 3 terms is constant. We can see that 4 is constantly being subtracted.

\(a_{n}=a+(n-1)d\)  is the formula for an arithmetic sequence.

\(a_{n}\) = nth term

a = the first term in the sequence

n = term you are looking for (in this case 45)

d = common difference between the terms (in this case -4)

∴

\(a_{n}=a+(n-1)d\)

\(a_{45} =208+(45-1)(-4)\\a_{45}=32\)

Answer:

Rs 6900

Step-by-step explanation:

To calculate the tax amount the girl should pay in a year, we need to determine the taxable income and then apply the corresponding tax rates.

The taxable income is calculated by subtracting the tax-free allowance from the girl's early income:

Taxable Income = Early Income - Tax-Free Allowance

Taxable Income = 150,000 - 100,000

Taxable Income = 50,000

Now, we can calculate the tax amount based on the given tax rates:

For the first 20,000 rupees, the tax rate is 12%:

Tax on First 20,000 = 20,000 * 0.12

Tax on First 20,000 = 2,400

For the remaining taxable income (30,000 rupees), the tax rate is 15%:

Tax on Remaining 30,000 = 30,000 * 0.15

Tax on Remaining 30,000 = 4,500

Finally, we add the two tax amounts to get the total tax she should pay in a year:

Total Tax = Tax on First 20,000 + Tax on Remaining 30,000

Total Tax = 2,400 + 4,500

Total Tax = 6,900

Therefore, the girl should pay 6,900 rupees in tax in a year.

Answer:

187 people

Step-by-step explanation:

5 to 6 is the same as 5/6. 5 is the men and 6 is the women. We know that there are 102 women so we can arrange this equation.

\(\frac{5}{6}\)  = \(\frac{x}{102}\)

Re-arrange the equation to find x, or the number of men in the company.

\(\frac{(102*5)}{6}\) = x

x = 82

We have found the number of men in the company. Now add the number of men and women.

102 + 82 = 187

187 total people!

Answer: 187 employees

Step-by-step explanation:

ratio of men to women: 5:6

number women working for company: 102

to work out the number of men working for the company, you must first find out what you have to multiply 6 by to get to 102

therefore you do 102/6 which is 17

now you do 17x5 to work out how many men are working for the company which is 85

total number of employees: 102+85=187

The book is opened to pages 11 and 12.

How to get the product of the page

x * (x + 1) = 132

Expanding the equation, we get:

x² + x = 132

To solve for x, we need to rewrite the equation as a quadratic equation:

x²+ x - 132 = 0

Now, we can factor the quadratic equation:

(x - 11)(x + 12) = 0

This equation has two solutions for x:

x = 11

x = -12

Since page numbers cannot be negative, we discard the second solution. Thus, the left-hand page number is 11, and the right-hand page number is 11 + 1 = 12.

The number in the sequence closest to 300 is 320.

What is sequence?

In mathematics, a sequence is an ordered list of numbers or other objects that follow a specific pattern or rule. Each element in the sequence is called a term, and the position of a term in the sequence is called its index.

To find the number in the sequence closest to 300, we can subtract 110 from 300 to get 190, and then divide by 30 to find how many additional terms we need to add to the sequence after 110:

(300 - 110) / 30 = 6

So we need to add 6 more terms to the sequence after 110.

The next term in the sequence after 110 is:

110 + 30 = 140

And the 6th term after that is:

140 + 30(6) = 320

So the number in the sequence closest to 300 is 320.

The slope of the tangent line at (x,f(x)) is given by the derivative f'(x). Thus, we have: The function f(x) is:
f(x) = -4/x - (7/5)/x^5 + 27/5

f'(x) = 4/x^2 - 7/x^6

To find the function f(x), we need to integrate f'(x) with respect to x. We have:

∫ f'(x) dx = ∫ (4/x^2 - 7/x^6) dx

Integrating each term separately, we get:

f(x) = -4/x - 7/(5x^5) + C

where C is the constant of integration. We can find the value of C by using the fact that the curve passes through the point (1,0):

0 = -4/1 - 7/(5*1^5) + C

C = 4/5

Therefore, the function f(x) is:

f(x) = -4/x - 7/(5x^5) + 4/5

Note that this function is defined for x > 0, as specified in the problem statement.

By forming and solving the equations we know that the ceiling bulbs and natural bulbs cost $12.30 and $4.46 respectively.

The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions.

An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values.

As in 3x + 5 = 15, for example.

There are many different types of equations, including linear, quadratic, cubic, and others. Let's learn more about math equations in this tutorial.

So, we can form 2 equations as follows:

5n + 2c = 23 ⇒ n = (23 - 2c)5 ...(1)

3n + 4c = 25 ...(2)

Now, insert n = (23 - 2c)5 in equation (2).

3n + 4c = 25

3(115 - 10c) + 4c = 25

345 - 30c + 4c = 25

-26c = - 320

c = 12.30

Now, insert c = 12.30 in equation (1):

Step-by-step explanation:

Subtract 2 from 47 because each ride is $2 then divide 3 from 45 to get 15 miles $3 per mile to check you could multiply to 15 to get 45.

The correct simplified form of the expression is x + 5.

a) The mistake that Hannah has made is incorrectly combining the terms 3x and -2x. Instead of subtracting the coefficients of x, she subtracted the entire expression 2x from 3x.

b) To simplify the expression correctly, we need to combine like terms. In this case, the like terms are the ones with the variable x.

The expression 3x + 5 - 2x can be rewritten as (-2x + 3x) + 5.

Now, let's combine the like terms:

(-2x + 3x) + 5 = x + 5

Therefore, the correct simplified form of the expression is x + 5.

To further clarify, Hannah mistakenly thought that subtracting 2x from 3x would result in 1x (or just x). However, when subtracting or adding terms with the same variable, we need to consider the coefficients. In this case, 3x - 2x simplifies to x, not 1x.

It's important to pay attention to the signs and operations when combining terms. In this scenario, Hannah overlooked the need to subtract the coefficients of x and ended up with an incorrect result.
