Answer:

Tthe area of the shaded region is [tex](x^{2}-3x+36)\ unit^{2}[/tex]

Step-by-step explanation:

we know that

To find the area of the shaded region (blue region), subtract the area of the smaller rectangle from the area of the larger square

so

Find the area of the larger square

[tex]A=(x+1)^{2}=(x^{2}+2x+1)\ unit^{2}[/tex]

Find the area of the smaller rectangle

[tex]A=5(x-7)=(5x-35)\ unit^{2}[/tex]

Answer:

11/6 or decimal 1.8333... + 4.9 = 6.733333....

Step-by-step explanation:

Simplify the following:

(3 + 2/3)/2

Express 4/6 in its lowest form by cancelling out gcd(4, 6) = 2 from the numerator and denominator. 4/6 = (2×2)/(2×3) = 2/3:

(2/3 + 3)/2

Put 3 + 2/3 over the common denominator 3. 3 + 2/3 = (3×3)/3 + 2/3:

((3×3)/3 + 2/3)/2

3×3 = 9:

(9/3 + 2/3)/2

9/3 + 2/3 = (9 + 2)/3:

((9 + 2)/3)/2

9 + 2 = 11:

(11/3)/2

11/3×1/2 = 11/(3×2):

11/(3×2)

3×2 = 6:

Answer:  11/6 or decimal 1.8333... + 4.9 = 6.733333....

Answer:

5/8

Step-by-step explanation:

5/8 is equal to 5 divided by 8 and your dividing 5 so all the friends can have a equal amount. every friend would also get 5/8 of a apple

Every friend would get 5/8 parts of the total apple.

A fraction is a part of a whole number, and a way to split up a number into equal parts.

Given that, 8 friends want to share 5 apples equally. We need to find that what fraction will each person get,

Since, we have 5 apples, which is to be distributed to 8 persons,

To find the same, we will have to, divide 5 apples equally among 8 persons,

Therefore,

If we divide 5 by 8 then the faction of 5/8 of the whole is the part that each of the 8 friends going to have,

Hence, each friend would get 5/8 parts of the total apple.

Answer:

The answer is ellipse; 23° to the nearest degree ⇒ answer (d)

Step-by-step explanation:

* At first lets talk about the general form of the conic equation

- Ax² + Bxy + Cy²  + Dx + Ey + F = 0

∵ B² - 4AC < 0 , if a conic exists, it will be either a circle or an ellipse.

∵ B² - 4AC = 0 , if a conic exists, it will be a parabola.

∵ B² - 4AC > 0 , if a conic exists, it will be a hyperbola.

* Now we will study our equation:

- 9x² + 4xy + 5y² - 40 = 0

∵ A = 9 , B = 4 , 5 = 5

∴ B² - 4 AC = (4)² - 4(9)(5) = -164 < 0

∴ B² - 4AC < 0

∴ If a conic exists, it will be either a circle or an ellipse.

* To find the type of the graph lets check;

- If A and C are nonzero, have the same sign, and are not

 equal to each other, then the graph is an ellipse.

- If A and C are equal and nonzero and have the same

 sign, then the graph is a circle.

∵ A and C have same signs and are not equal

∴ The graph is an ellipse

* If we have term xy ⇒ B ≠ 0

∴ The graph is rotate by angle Ф

* To find the angle of rotation use the rule:

- cot(2Ф) = (A - C)/B

∵ A = 9 , B = 4 , C = 5

∴ cot(2Ф) = (9 - 5)/4 = 4/4 = 1

∴ tan(2Ф) = 1

∴ 2Ф = 45°

∴ Ф = 22.5° ≅ 23° to the nearest degree

* The answer is ellipse; with angle of rotation = 23°

The Zero Product Property in mathematics states that if the product of two numbers is zero, then at least one of the numbers must be zero. You typically use this property when solving quadratic equations by setting each factored term equal to zero and then solving for every variable.

The Zero Product Property is an essential concept in algebra, particularly when it comes to solving quadratic equations. The Zero Product Property states that if the product of two numbers, terms, or factors is zero, then at least one of the factors must be zero. In simple terms, if a * b = 0, then a has to be zero, or b has to be zero, or both.

To use the Zero Product Property, you usually start by setting an equation equal to zero. For example, let's solve the quadratic equation x^2 - 5x = 0. First, you would factor the equation to (x)(x-5) = 0. Now, using the Zero Product Property, we can set each factor equal to zero and solve for x. This gives us x = 0 and x = 5.

Step-by-step explanation:

In a parallelogram opposite angles are congruent. Therefore we have the equation:

10y - 29 = 7y +19               add 29 to both sides

10y = 7y + 48               subtract 7y from both sides

3y = 48              divide both sides by 3

Step-by-step explanation:

Given in the question a logarithm expression

[tex]125^(log_{5}2)[/tex]

We will use Exponent of Log Rule

[tex]b^(log_{b}k) = k[/tex]

here b = 5

         k = 2

Suppose

[tex]125^(log_{5}2) = x[/tex]

take cube root on both sides of this equation

[tex]\sqrt[ 3]{(125^(log_{5}2)}=\sqrt[3]{x}[/tex]

[tex]\sqrt[3]{(125)} ^(log_{5}2)=\sqrt[3]{x}[/tex]

[tex]5^(log_{5}2)}=\sqrt[3]{x}[/tex]

2 = ∛x

to remove cube root take cube on both side

x = 8

so [tex]125^(log_{5}2 )[/tex] = 8

Answer:

B

Step-by-step explanation:

A transformation of T(a,b) in the equation would give this form:

[tex](x-a)^2+(y-b)^2=8[/tex]

So, T(4,3) means translation of 4 units in x and 3 units in y. Thus, we can write:

[tex](x-4)^2+(y-3)^2=8[/tex]

Expanding and rearranging, we get:

[tex](x-4)^2-(y-3)^2-8=0\\x^2-8y+16-y^2+6y-9-8=0\\x^2-y^2-8x+6y-1=0[/tex]

The area left to build is [tex]\frac{704}{60}\ m^{2}[/tex]

Step-by-step explanation:

The question in English is

The area of a property in square meters, measures 704/5. A house is built that occupies 5/6 of the total area. Half of the remaining area is used to build a terrace, how much area is left to build?

we know that

The total area represent the fraction 6/6

A house represent the fraction 5/6 of the total area

The remaining area represent the fraction  (6/6)-(5/6)=1/6 of the total area

If half of the remaining area is used to build a terrace

then

the area of the terrace represent the fraction (1/6)/2=1/12 of the total area

therefore

The area left to build represent the fraction 1/12 of the total area

so

[tex](\frac{1}{12})\frac{704}{5} =\frac{704}{60}\ m^{2}[/tex]

Hence, the lakes' altitudes varied by 40 feet. To sum up: Average: around -26.3 feet, Average: -18 feet , Zero mode and 30 to 40 ft.

The mean, a statistic of central tendency in mathematics, is the average of a group of numerical values. It is also frequently known as the geometric average. A set of values' mean is calculated by adding up all of the values and dividing the result by the amount of values in the set. The mean can be determined, for instance, if the set of values is 3, 5, 7, 9, and 11, by multiplying the values together and dividing them by the total amount of numbers: Mean = (3 + 5 + 7 + 9 + 11) / 5 = 7 .As a result, 7 represents the set's mean value.

given

The median altitude of the lakes is -18 feet because the middle number is -18.

Mode: To identify the mode, we search the collection for the number that pops up the most often. There is no mode because no number appears more than once in this instance.

Range: To get the range, divide the largest by the smallest number:

The original price of the bike helmet was $68.25, calculated by understanding that the $54.60 Kelly paid represented 80% of the original price after a 20% discount.

Kelly paid $54.60 for a bike helmet that was 20% off the original price. To find the original price of the helmet, we need to understand that the price Kelly paid is 80% of the original price, after the discount was applied. Therefore, the equation to find the original price (OP) is:

54.60 = 0.80 × OP

To solve for OP, we divide both sides of the equation by 0.80:

OP = 54.60 / 0.80

OP = $68.25

Thus, the original price of the bike helmet was $68.25.

Answer:  The correct options are

(B) [tex]x=\dfrac{11+\sqrt{61}}{2}.[/tex]

(D) [tex]x=\dfrac{11-\sqrt{61}}{2}.[/tex]

Step-by-step explanation:  We are given to select the values of x that are the roots of the following polynomial :

[tex]x^2-11x+15.[/tex]

The quadratic equation formed by the given polynomial will be

[tex]x^2-11x+15=0~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

we know that

the solution set of a quadratic equation [tex]ax^2+bx+c=0,~~a\neq 0[/tex] is given by

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}.[/tex]

From equation (i), we have

a = 1, b = -11  and  c = 15.

Therefore, the roots of equation (i) will be given by

[tex]x=\dfrac{-(-11)\pm\sqrt{(-11)^2-4\times1\times15}}{2\times1}\\\\\\\Rightarrow x=\dfrac{11\pm\sqrt{121-60}}{2}\\\\\\\Rightarrow x=\dfrac{11\pm\sqrt{61}}{2}.[/tex]
