17=(-14)+K solve for K

that is true if that's 1/3n=7/12

if it's 1/3n-7/12 then the first step is to equal it to zero

Yes, the second step in solving 1/3n = 7/12 is to divide both sides of the equation by 1/3.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In a fraction say (x/y), [y] is called denominator.

We have the equation -

(1/3)n = (7/12)

We have -

(1/3)n = (7/12)

Dividing both sides by (1/3), we get -

[(1/3)/(1/3)]n = [7/12 x 3]

n = 7/4

Therefore, yes, the second step in solving 1/3n = 7/12 is to divide both sides of the equation by 1/3.

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

Answer:

The volume = [tex]5x^{5}+4x^{4}+x^{3}[/tex]

Step-by-step explanation:

* The rule of the volume of the rectangular prism:

- the volume of any prism = base area × height

∵ The base of the rectangular prism is rectangle

∵ Area any rectangle = Length × Width = l × w

∴ The volume of the rectangular prism = l × w × h

* In the problem:

∵ l = x , w = x² , h = 5x² + 4x + 1

∴ The volume = (x)(x²)(5x² + 4x + 1)

* We will simplify it

- Multiply x by x² and then multiply the answer by the bracket

∵ x × x² = x³

∴ x³(5x² + 4x + 1)

∵ x³ × 5x² = 5x^5

∵ x³ × 4x = 4x^4

∵ x³ × 1 = x³

∴ The volume = [tex]5x^{5}+4x^{4}+x^{3}[/tex]

Area of circle = [tex]\pi[/tex][tex]r^{2}[/tex]

First, we can put in our values. For now, we can leave [tex]\pi[/tex] alone.

Our radius is 5.5 so we have to square it which gives us a product of 30.25

then, we can multiply our radius squared by [tex]\pi[/tex] and we get

Area, A = 95.033177771091 [tex]in^{2}[/tex]

The answer is:

[tex]cos(R)=\frac{1}{2}[/tex]

Since it's a right triangle and we need to know the adjacent side of the triangle, in order to find cos(R), we can use the Pythagorean Theorem.

Pythagorean Theorem formula:

[tex]c^{2}=a^{2} +b^{2}[/tex]

Where:

[tex]c=hypotenuse=20\\a=FirstTriangleSide=AdjacentSide\\b=SecondTriangleSide=OppositeSide=10\sqrt{3}[/tex]

So, the adjacent side will be:

[tex]AdjacentSide=\sqrt{c^{2}-b^{2}}=\sqrt{20^{2}-(10\sqrt{3})^{2}}=\sqrt{400-100*3} \\AdjacentSide=\sqrt{100}=10[/tex]

Now, that we know the adjacent side, we can calculate cos(R), so:

[tex]cos(R)=\frac{AdjacentSide}{Hypotenuse}=\frac{10}{20}=\frac{1}{2}[/tex]

Have a nice day!

Answer:

cosine∠R = 1/2

Step-by-step explanation:

We have to find the figure of triangle.

We have to find the cosine∠R.

First we find the base of triangle.

We have formula: Hypotenuse² = Base² + perpendicular²

Hypotenuse = 20

Base= ?

perpendicular = 10√3

Applying formula we get,

Base = √20² - (10√3)²

base = 10

As we know that :

cosФ = base/hypotenuse

cosine∠R = 10/20

cosine∠R = 1/2 is the result.

Answer:

g + l = 38

g = l + 8

l + 8 + l = 38

2l = 30

l = 15, g = 23

The numbers are 15 and 23. The lesser number is 15, and the greater number is 23.

To find the two numbers, we can set up a system of linear equations. Using substitution method, we find that the numbers are 23 and 15.

To solve this problem, we can set up a system of linear equations. Let's assume that the two numbers are x and y, with x being the greater number.

We're given that the sum of the two numbers is 38, so we can write the equation x + y = 38.

We're also given that the greater number is 8 more than the other number, so we can write the equation x = y + 8.

We can solve this system of equations using substitution or elimination method. Let's use substitution method.

From the second equation, we can substitute the value of x in the first equation:

y + 8 + y = 38

2y + 8 = 38

2y = 30

y = 15

Now, substitute the value of y in the second equation:

x = 15 + 8

x = 23

Therefore, the two numbers are 23 and 15.

It is 104.5

Using the tangent function with the given angle of elevation and distance to the tower, we can calculate that the height of the tower is approximately 106.1 feet, which is answer C.

This is a question about trigonometry, specifically using tangent ratios. Given that the angle of elevation from Mindy to the top of the cell phone tower is 75 degrees and Mindy is standing 28 feet from the base of the tower, we need to find the height of the tower. The tangent of an angle in a right triangle is defined as the opposite side (the height of the tower in this case) divided by the adjacent side (the distance from Mindy to the tower).

Using the tangent function gives us: Tan(75) = height / 28. Multiplying both sides by 28 gives us the height: height = 28*Tan(75). Calculating this gives us the height of the tower, which is approximately 106.1 feet, therefore Option C is correct.

Answer:

The answer is the third

S = 16 t²

Step-by-step explanation:

* Lets study the order pairs in C to find what is the relation

  between the input (t) and the output (S)

∵ C = {(t , S): (0 , 0) , (1 , 16) , (2 , 64) , (3 , 144) , .............}

∵ (0 , 0) is the first point

∴ There is no plus or minus in the relation between S and t

∴ We refused the last answer S = 16(t + 1)² because

  if t = 0 then S = 16(0 + 1) = 16 ≠ 0

- If we chose the first answer:

∵ S = 16t  

∵ t = 0 ⇒ S = 16(0) = 0 ⇒ its right

∵ t = 1 ⇒ S = 16(1) = 16 ⇒ its right

∵ t = 2 ⇒ S = 16(2) = 32 ⇒ its wrong

∴ We refused the first answer

- If we chose the second answer:

∵ S = (16t)²

∵ t = 0 ⇒ S = (16×0)² = 0 ⇒ its right

∵ t = 1 ⇒ S = (16×1)² = 256 ⇒ wrong

∴ We refused the second answer

- If we chose the third answer:

∵ S = 16 t²

∵ t = 0 ⇒ S = (16)(0)² = 0 ⇒ its right

∵ t = 1 ⇒ S = (16)(1)² = 16 ⇒ its right

∵ t = 2 ⇒ S = (16)(2)² = 16 × 4 = 64 ⇒ its right

∵ t = 3 ⇒ S = (16)(3)² = 16 × 9 = 144 ⇒ its right

∴ every time we multiply 16 by the square of the value of t

∴ We accept the third answer

Step-by-step explanation:

Since -4 is indeed equal to -4, we can say that D, there are many solutions since all real numbers are a solution because any number is equal to itself :)

The equation 5(x-2)+6 = 2x-4+3x has infinitely many solutions.

To solve the equation 5(x-2)+6 = 2x-4+3x, we start by distributing the 5 to the terms inside the parentheses: 5x - 10 + 6 = 2x - 4 + 3x. Next, we combine like terms on both sides of the equation: 5x - 4 = 5x - 4. This simplifies to 0 = 0, which means that both sides of the equation are equal.

Since the equation is true no matter what value of x we choose, this means that the equation has infinitely many solutions.

Answer:

CD = two square root of 10 end square root

Step-by-step explanation:

To find the length of a segment, use the distance formula. Substitute the order pairs for the endpoints of the segment. CD has the end points (-7, -4) and (-1, -2).

[tex]d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2} \\\\d = \sqrt{(-4--2)^2 + (-7--1)^2} \\\\d = \sqrt{-2^2 + -6^2}\\\\d = \sqrt{4 + 36}\\\\d=\sqrt {40} = 2\sqrt{10}[/tex]

To find the length of segment CD, use the distance formula:
[tex]\[d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}.\][/tex] For CD with endpoints (-7, -4) and (-1, -2),
[tex]\[d = \sqrt{40} = 2\sqrt{10}.\][/tex]

To determine the length of a segment, utilize the distance formula by substituting the coordinates of the endpoints. In the case of segment CD, the endpoints are (-7, -4) and (-1, -2).

To determine the length of a segment, the distance formula is applied, denoted as:

[tex]\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \][/tex]

For segment CD with endpoints (-7, -4) and (-1, -2), the distance is computed as follows:

[tex]\[ d = \sqrt{(-1 - (-7))^2 + (-2 - (-4))^2} \][/tex]

This simplifies to:

[tex]\[ d = \sqrt{(6)^2 + (2)^2} \][/tex]

[tex]\[ d = \sqrt{36 + 4} \][/tex]

[tex]\[ d = \sqrt{40} \][/tex]

Hence, the length of segment CD is [tex]\(\sqrt{40}\)[/tex] units. This result can be further expressed as [tex]\(2 \sqrt{10}\)[/tex] by factoring out the square of the largest perfect square, which is 4, from 40. Therefore, the exact length of segment CD is [tex]\(2 \sqrt{10}\)[/tex] units.

Answer with explanation:

The value of square -9 is not -3 ([tex] \sqrt { - 9 } \neq - 3 [/tex]).

It is because we cannot take a square root of a negative number since any number multiplied by itself is a positive number so you never get a negative value.

Therefore, it given an error if you try to take a square root of a negative number on a calculator.

Answer:

The value of √-9 is not -3 because we cannot take the square root of negative numbers

Step-by-step explanation:

It is not possible to take square root of a negative number.

If any positive number we can take its square roots.

-9 is a negative number.

√9 = ±3 means that,

√9 = 3 or √9 = -3

3 * 3 = 9 and -3 * -3 = 9

Answer:

length of x is 50 yards

Step-by-step explanation:

Pythagorean Theorem:  a^2 + b^2 = c^2

30^2 + 40^2 = c^2

900 + 1600 = c^2

2500 = c^2   need to solve for c, square root both sides

50 = c

The length of the diagonal is 50 yards. The diagonal of a rectangle divides the rectangle into two right-angled triangles. Thus, by applying the Pythagoras theorem we can able to find the length of the diagonal.

The theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle) and the algebraic notation, [tex]a^2 + b^2 = c^2[/tex].

The diagonal of a rectangle divides the rectangle into two halves of right-angled triangles.

The length and breadth of the rectangle are 40 yards and 30 yards.

The diagonal x divides the rectangle. So, it becomes a common hypotenus for the two right-angled triangles.

So, applying the Pythagoras theorem.

x^2 = (40)^2 + (30)^2

     = 1600 + 900

     = 2500

Thus, the value of x is 50 yards.

Therefore, the length of the diagonal is 50 yards.
