Answer: B .. Y = +- square root X+36

Step-by-step explanation:

Answer:

Saving=£450

Spent=£200

Step-by-step explanation:

Ratio of saving to spending is 9:4

She inherits £650

So to determine her saving

It will be

9+4=13

Since her saving is 9

So, 9/13 × 650

5850/13

=450

So her saving is£450

To determine what she spent

4/13 × 650

2600/13

200

Saving=£450

Spent=£200

The amount she saves is  £450 and the amount she spends is £200.

Step-by-step explanation:

Given,

The amount she has = £650

The ratio of saving to spending money is 9:4

To find the amount she saves and she spends.

Let,

The amount she saves = 9x

The amount she spends = 4x

According to the problem,

9x+4x = 650

or, 13x = 650

or, x = [tex]\frac{650}{13}[/tex] = 50

Hence,

The amount she saves =  £50×9 =  £450

The amount she spends = £50×4 = £200

Answer:

The second answer

XYZ-RQS

Step-by-step explanation:

Answer:

[tex]\theta=128.5^{\circ}[/tex]

Step-by-step explanation:

The given angle measure is

[tex]\theta=\dfrac{257\pi}{360}[/tex]

We need to convert the radian measure to degree.

To convert radian to degree, multiply the given measure by [tex]\frac{180^{\circ}}{\pi}[/tex].

[tex]\theta=\dfrac{257\pi}{360}\times \dfrac{180^{\circ}}{\pi}[/tex]

On simplification, we get

[tex]\theta=128.5^{\circ}[/tex]

Hence, the required measure is [tex]\theta=128.5^{\circ}[/tex].

Answer:

x=300

Step-by-step explanation:

Multiply both sides by 10

0.4x·10=0.5x·10-30·10

Refine

4x=5x-300

Subtract 5x from both sides

4x-5x=5x-300-5x

Simplify

-x=-300

Divided both sides by -1

-x/-1=--300/-1

Simplify this and you will get x=300

The value of c that makes the expression x² − 15x + c a perfect square trinomial is obtained by squaring half the coefficient of x, which in this case is 225/4. Therefore option A is the correct answer.

To find the value of c that makes the expression x² − 15x + c a perfect square trinomial, we need to find a value for c such that the trinomial can be expressed as the square of a binomial.

This binomial will have the form (x - h)², where h is half the coefficient of the x term in the original trinomial.

In this case, the coefficient of x is -15.

Half of -15 is -15/2.

Squaring this value will give us c. Thus, (-15/2)² equals 225/4.

The value of c that makes the expression a perfect square trinomial is 225/4.

Answer: The equation is y = 0.25/(x - 4) + 3

Step-by-step explanation:

If we have a function y = f(x)

A compression means that we multiply the function by a factor smaller than 1.

Then the vertical compression by a factor of 0.25 is:

y = 0.25*f(x)

a translation by A units to the right, means that we need to valuate the function in x - A.

So now we have:

y = 0.25*f(x - 4)

A translation in the y-axis means that we need to add a constant to the equation, then if we tralate it by 3 units up, we have:

y = 0.25*f(x - A) + 3

Then, if f(x) = 1/x

Our new equation is:

y = 0.25/(x - 4) + 3

Answer:

g ( x ) = 0.25 / ( x - 4 ) + 3

Step-by-step explanation:

Solution:-

- The given function is defined as an inverse function:

                           f ( x ) = 1 / x

- The transformation on the function of f ( x ) are of three kinds. We will use a general form to look at the effect of each transformation.

             [tex]f ( x ) --- > g ( x ) = [ \frac{a}{( x +/- b)} ] + c[/tex]

Where a,b, and c are constants for transformation.

- The effect of constant a:

            a > 1 ------ > Flattens the graph  

            0 < a < 1 -------- > Compresses the graph vertically

- The effect of constant b:

            b > 0 ------ > Horizontal shift to left

            b < 0 -------- > Horizontal shift to right

- The effect of constant c:

            c > 0 ------ > Vertical shift up

            c < 0 -------- > Vertical shift down

- Now we will determine the result of function after each transformation.

                        k ( x ) = 0.25 / x

                      j ( x ) = 0.25 / ( x - 4 )

                     g ( x ) = 0.25 / ( x - 4 ) + 3

Hence, the resulting function of all the mentioned transformations of original function f ( x ) is given as g ( x ):

                    g ( x ) = 0.25 / ( x - 4 ) + 3

The volume of the prism with a pentagonal base area of ([tex]\frac{124}{\tan36^\circ}[/tex])m² and height of 13 m is approximately 2218.73  m³ when rounded to the nearest hundredth.

The volume of a prism is calculated by multiplying the area of the base by the height of the prism. For a prism with a pentagonal base, if the area of the base is ([tex]\frac{124}{\tan36^\circ}[/tex])m² and the prism's height is 13 m, then the volume V is found by the following calculation:

V = area of base × height
V = ([tex]\frac{124}{\tan36^\circ}[/tex]) × 13

First, calculate the numerical value for tan36°:

tan36° ≈ 0.7265

Then plug this value into the formula:

V = (124÷0.7265) × 13
V ≈ 2218.73 m³

The volume of the prism is therefore approximately 2218.73 m³, rounded to the nearest hundredth.

Answer:

Here you go, your equation should look a lot like this:

x²-16 -----> (x+4)(x-4).

Step-by-step explanation:

It's an example of what you should be writing depending on your answer. You did not include any details about your question.

The polynomial that is a difference of squares will be x²-16. It is factored as (x+4)(x-4).

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order. Polynomials are used in management, computer, and math-based occupations. Variables and constants are utilized to define numbers that are known and unknown in expressions in all professions that need proficiency with polynomials.

We have to define a polynomial that is a difference of squares we have to also do factors for that polynomial.

The polynomial that is a difference of squares is found as,

x²-16

Used the below identity in order to factorize the polynomial,

a²-b²=(a+b)(a-b)

16 in its square form is written as 4².

x²-4² = (x+4)(x-4)

Thus, the polynomial that is a difference of squares will be x²-16. It is factored as (x+4)(x-4).

Answer:

1 -- 3/25

2 -- 1/25

3 -- 4/24

Step-by-step explanation:

To find the probability of a randomly selected person being in any category, divide the amount of people in that category by the total amount of people.

We can find the total amount of people by adding the amount of people with each blood type.

Total = O + A + B + AB = 22 + 20 + 6 + 2 = 50

There are 50 total people in this group. Now we can find the probability of randomly selecting a person from each category.

Probability of type B

There are 6 people with type B blood. The probability of randomly selecting a person from this group is 6/50, or 3/25.

Probability of type AB

There are 2 people with type AB blood. The probability of randomly selecting a person from this group is 2/50, or 1/25.

Probability of type B or AB

We need to find the amount of people who are in either group. There are 6 people with type B blood and 2 people with type AB blood, so 8 people satisfy this criteria. The probability of randomly selecting a person with type B or AB blood is 8/50, or 4/25.

Answer:

B

Step-by-step explanation:

Given

3x² + 21x + 18 ← factor out 3 from each term

= 3(x² + 7x + 6) ← factor the quadratic

Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 7)

The factors are + 6 and + 1, since

6 × 1 = 6 and 6 + 1 = 7, thus

x² + 7x + 6 = (x + 6)(x + 1)

Thus

3x² + 21x + 18 = 3(x + 6)(x + 1) → B

Asher will need c. 936 cm² of paint to cover both the bookends.

Step-by-step explanation:

Step 1:

To determine the amount of paint needed, we determine the surface area of the triangular prisms.

To calculate the triangular prism's surface area, we calculate the areas of all the 5 sides. We divide the prism into 2 triangles and 3 rectangles, find the areas individually and then sum them all up in order to determine the area of the entire triangular prism.

Step 2:

There are two triangles with base lengths of 9 cm and heights of 12 cm. A triangle's area is half the product of the base length and its height.

Area of 1 triangle = [tex]\frac{1}{2} (9)(12) = 54[/tex] cm².

Area of both triangles = 2× Area of 1 triangle [tex]= 2(54)[/tex] = 108 cm².

Step 3:

There are three rectangles with a common length of 10 cm but there are three different widths. Any rectangle's area is calculated by multiplying the rectangle's length with its width.

Area of a rectangle with width 15 cm [tex]= (10)(15) = 150[/tex] cm².

Area of a rectangle with width 9 cm [tex]= (10)(9) = 90[/tex] cm².

Area of a rectangle with width 12 cm [tex]= (10)(12) = 120[/tex] cm².

Step 4:

The area of the entire triangular prism = Area of 2 triangles + Area of all the 3 rectangles = [tex]108+150+90+120 = 468[/tex] cm².

This is the surface area of 1 bookend. As both the bookends are similar.

The surface area of 2 bookends [tex]= 2(468) = 936[/tex] cm².

Asher will need 936 cm² of paint to cover both the bookends.
