Write 13/12 as a mised number

Answer:

Step-by-step explanation:

If Boden's account has a principal of $600 and a simple interest rate of 3.9%, then the interest he earns each year can be calculated as follows:

Simple Interest = Principal * Rate * Time = $600 * 3.9% * 1 = $23.40

So, after one year, the amount of money in the account will be $600 + $23.40 = $623.40

This process can be repeated for multiple years to find the amount of money in the account for a specific time period.

Using the formula of area of rectangle and square, the cost of painting is Rs. 1335

The area of a rectangle is equal to the product of its length and width. Mathematically, it can be represented as:

Area = Length × Width

In this problem, we need to substitute the values and calculate the area of the rectangular wall and then subtract the area of the window from it.

Area of rectangle = 15 * 7 = 105m²

The area of the window is calculate by using the formula of area of square.

Area of square = 4 * 4 = 16m²

Area of wall painted = 105 - 16 = 89m²

The cost of painting one square meter = Rs. 15

1m² = Rs. 15

89m² = x

x = 15 * 89

x = Rs. 1335

The cost is Rs. 1335

A library has 2500 books.40% of the books are fiction, number of not fiction books are 1500.

A percentage is a relative figure that represents one tenth of a quantity. Since one percent (symbolised as 1%) is equal to one tenth of anything, 100 percent stands for everything, while 200 percent refers to double the amount specified.

Total amount of book in library are 2500 ,

Out of that 40% are fiction so the number of the non fiction books are 60%

so 60% of 2500 will give us the value of non fiction books,

Number of non fiction = 2500 x 60%

= 2500 x 60/100

= 25 x 60

= 1500

Therefore,  Number of non fiction books are 1500.

The Pythagorean Theorem, sometimes known as the Pythagorean Theorem, is the basic Euclidean geometry relationship between a right triangle's three sides. According to this rule, the area of a square with the hypotenuse side equals the sum of the areas of squares with the other two sides. The Pythagorean Theorem, often known as the generic algebraic notation a2 + b2 = c2, states that the square that crosses the hypotenuse of a right triangle opposite the right angle equals the sum of the squares that span the sides of a right triangle.

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Let x be the number of biology textbooks sold. Then, the number of psychology textbooks sold was x - 61.

The combined total of the two types of textbooks sold was 251, so we can write an equation:

x + (x - 61) = 251

Expanding the right side:

2x - 61 = 251

Adding 61 to both sides:

2x = 312

Dividing both sides by 2:

x = 156

the number of psychology textbooks sold =  x - 61

                                                                      =  156 - 61

                                                                      =  95

The ratio of used books to all books is 7 : 13 and  the ratio of new books to used books is 6 : 7

If there are 13 books on a shelf. 6 of these books are new.

(a) The ratio of used books to all books

Number of all books = 13

Number of used books = total no. of books - no. of new books

                                       =  13 - 6

                                       = 7

So, ratio of used books to all books

= no. of all books : no. of total books

= 7 : 13

Thus, the ratio of used books to all books = 7 : 13

(b) The ratio of new books to used books

Number of new books = 6

Answer:

  (d)  C'(-1, 14)

Step-by-step explanation:

You want the coordinates of C' after the point C(-1, -6) is reflected across the line y = 4.

Reflection across the horizontal line y=4 will not change the x-coordinate of the point, so C' has an x-coordinate of -1.

The point (-1, 4) on the line of reflection will be the midpoint of C and C', so we have ...

  (C +C')/2 = (-1, 4)

  C +C' = 2(-1, 4) = (-2, 8) . . . .  .multiply by 2

  C' = (-2, 8) -C

  C' = (-2, 8) -(-1, -6) = (-1, 8+6)

  C' = (-1, 14)

__

Additional comment

Effectively, the reflection across the line y=4 is the transformation ...

 (x, y) ⇒ (x, 8 -y)

Answer:

C'(-1, -6).

Step-by-step explanation:

the reflection across y = 4 for point C(-1, -6).

When reflecting a point across a horizontal line like y = 4, the y-coordinate remains the same, and the x-coordinate is inverted with respect to the line of reflection.

For point C(-1, -6), the y-coordinate remains -6, and the x-coordinate is inverted across y = 4:

New x-coordinate = -1

So, the reflected image of point C across y = 4 is C'(-1, -6).

None of the provided options match this reflection, so it seems there might be an error in the given answer choices. The correct reflection of point C(-1, -6) across y = 4 is C'(-1, -6).

Answer: In a parallelogram, opposite sides are equal in length and parallel, so if we subtract the vectors AB and BC from each other, we will get the vector for CD.

Given A = (4,0), B = (1.5,0), and C = (-3,-5), we can calculate the vectors AB and BC as follows:

AB = B - A = (1.5, 0) - (4, 0) = (-2.5, 0)

BC = C - B = (-3, -5) - (1.5, 0) = (-4.5, -5)

Next, we subtract these vectors to find the vector for CD:

CD = BC - AB = (-4.5, -5) - (-2.5, 0) = (-2, -5)

Finally, we add the vector CD to vertex C to find vertex D:

D = C + CD = (-3, -5) + (-2, -5) = (-5, -10)

So, the ordered pair for vertex D is (-5, -10).

$2,250 was invested at 2% and the remaining $3,500 was invested at 12%. The combined interest earned amount for the first year was $475.

The financial planner invested $5,750 of the couple's money. Let x be the amount of money invested in the savings account paying 2% annual simple interest and y be the amount of money invested in the riskier mini-mall development plan paying 12% annual simple interest. Since the combined interest earned for the first year was $475, we can write the equation 2x + 12y = 475. Since the total amount of money invested was $5,750, we can add the equation x + y = 5,750 to our system of equations. Solving the system of equations yields x = 2,250 and y = 3,500. Thus, $2,250 was invested at 2% and the remaining $3,500 was invested at 12%. The combined interest earned for the first year was $475.

Step-by-step explanation:

Given function:

[tex]f(x)=4(x-2)^3+2[/tex]

The point-of-symmetry of a cubic graph is its point of inflection.

To find the x-value of the point of inflection of a cubic function, differentiate the function twice:

[tex]f'(x)=12(x-2)^2[/tex]

[tex]f''(x)=24(x-2)[/tex]

Set the second differentiated function to zero and solve for x:

[tex]\implies 24(x-2)=0[/tex]

[tex]\implies x-2=0[/tex]

[tex]\implies x=2[/tex]

Substitute the found value of x into the original function to find the y-value of the point of inflection:

[tex]\implies y=4(2-2)^3+2[/tex]

[tex]\implies y=4(0)^3+2[/tex]

[tex]\implies y=0+2[/tex]

[tex]\implies y=2[/tex]

Therefore, the point of symmetry of the cubic function is (2, 2).

The inverse of a cubic function its reflection in the line y = x.

As the point of symmetry is (2, 2), then its reflection in the line y = x is also (2, 2).

So the point of symmetry on f⁻¹(x) is (2, 2).

The given function has an unrestricted domain and range.

The domain of the inverse function is the range of the function.

The range of the inverse function is the domain of the function.

Therefore, as the domain and the range of the original function are unrestricted, so are the domain and range of the inverse function.

The inverse of a cubic function with an unrestricted domain is its reflection across the line y = x.

Therefore, the graphs of f⁻¹(x) and f(x) are reflections across the line y = x.

To find the inverse of the given function, swap x and y:

[tex]\implies x=4(y-2)^3+2[/tex]

Rearrange to make y the subject:

[tex]\implies x-2=4(y-2)^3[/tex]

[tex]\implies \dfrac{x-2}{4}=(y-2)^3[/tex]

[tex]\implies \sqrt[3]{\dfrac{x-2}{4}}=y-2[/tex]

[tex]\implies y=\sqrt[3]{\dfrac{x-2}{4}}+2[/tex]

Replace y with f⁻¹(x):

[tex]\implies f^{-1}(x)=\sqrt[3]{\dfrac{x-2}{4}}+2[/tex]

As we have already established, the domain and range of the inverse function are unrestricted.  As each x-value has only one y-value associated with it, f⁻¹(x) is a function.
