A number's square root multiplied by another number's square root does not always equal the total of these two numbers' square roots, thus the square root of 16 is equal to 4.

It is possible to multiply an integer by its square root in order to obtain the original value. Square root of, end square root is the symbol for this mathematical concept. Contrary to squaring, finding a number's square root is the reverse. For instance, 3 is squared at 9, 32, and its square root at 9, which is 9, is equal to 3. It is simple to multiply by 9 since it is a perfect square.

So, there is a reverse relationship between squaring and getting the square root.

A statement which is supported by the information in the graph include the following: A. exactly 42% of the students chose green, black, or purple as their favorite color.

In order to determine the true statement based on the information provided in the given bar chart, we would calculate the total number of students as follows;

Total number of students = 6 + 4 + 8 + 7 + 9 + 3 + 4 + 9

Total number of students = 50 students.

For the number of students who chose green as their favorite color, we have the following:

Green = 6/50 × 100

Green = 0.14 × 100

Green = 14%.

For the number of students who chose black as their favorite color, we have the following:

Black = 8/50 × 100

Black = 0.16 × 100

Black = 16%.

For the number of students who chose purple as their favorite color, we have the following:

Purple = 6/50 × 100

Purple = 0.12 × 100

Purple = 12%.

Total percentage = 14% + 16% + 12%

Total percentage = 42%

let  [tex]tan^-^1 (\frac{4}{3})[/tex] = θ

so tan θ = 4/3

tan θ = p/b

Trignometic angle formula

so  p= 4k and b= 3k where k is a constant value.

h = [tex]\sqrt{p^2+b^2}[/tex]

=> [tex]\sqrt{16k^2+ 9k^2}[/tex]

=> 25k^2

=> 5k

where p is perpendicular , b is base and h is hypotenuse

so h= 5k

sin θ = p/h

=> 4k/5k

=> 4/5

cos  θ =b/h

=> 3k/5k

=> 3/5

and cos (2  [tex]tan^-^1 (\frac{4}{3})[/tex]) = cos (2θ)

cos (2θ) = 2 [tex]cos^2[/tex] θ -1

=> 2 * [tex]\frac{3}{5} ^2[/tex] - 1

The factor of (x + y)³ - (x³+y³) is 3xy is a factor of the given expression.

Factor of Expression:

The factor is part of the product. Both are factors of this term 5y because 5y represents 5 × y and 5 is multiplied by y to form 5y. Expressing a term as the product of two or more variables or numbers is called factorization. Sometimes we need to factorize arbitrary algebraic expressions. For example, y2 + y is factored as y(y+1). This means that y and y+1 are factors of y2 + y and a2- b2 = (a + b)(a - b). That is, (a + b ) and ( a-b) are factors of a² - b².

As we know,

(a + b)³ = a³ + b³ + 3a²b + 3ab²

The given expression can be simplified as,

   (x + y)³ - (x³ + y³) = ( x³ +y³ +3x²y + 3xy³) - (x³ +y³)

⇒ (x + y)³ - (x³ + y³) =  x³ +y³ +3x²y + 3xy³ - x³ - y³

This gives,

(x + y)³ - (x³ +y³) = 3x²y+ 3xy²

This can be written as,

(x + y)³ - (x³+y³) = 3xy(x + y)

Therefore, we can say that  3xy is a factor of the given expression.

For the year in which they earned $176,500, the partners will receive $52,950, $35,300, and $88,250 respectively.

Here let the partners be A, B, and C.

According to the question, A: B: C = 3: 2: 5

This implies that if the profits are divided into

3 + 2 + 5 = 10 equal parts, 3 of those parts will go to A, 2 of those parts will go to B and 5 of those parts will go to C.

Here the profits for the year are $176,500.

Now dividing them into 10 equal parts will give us the value of each part to be

$176, 500/10 = $17,650

Hence A will receive $17,650 X 3 = $52,950

B will receive $17,650 X 2 = $35,300

The derived units answers are 379 mg, 787 × 10^3 mg and 0.0743 kg.

What do you mean by units?

Unit is a quantity of constant magnitude which is used to measure the magnitudes of other quantities of the same manner

0.379 g = ? mg

as we know, 1 gram is equal to 1000 milligrams. i.e. 1 g = 1000 mg

∴ 0.379 × 1 g

= 0.379 × 1000 mg

= 379 mg

787 g = ? mg

as we know, 1 gram is equal to 1000 milligrams. i.e. 1 g = 1000 mg

∴ 787 × 1 g

= 787 × 1000 mg

= 787000 mg

= 787 × 10^3 mg

74.3 g = ? kg

as we know, 1 gram is equal to 1 / 1000 kilograms. i.e. 1 g = 1 / 1000 kg

∴ 74.3 × 1 g

= 74.3 × 1 / 1000 kg

= 74.3 / 1000 kg

= 0.0743 kg

Therefore, the derived units answers are 379 mg, 787 × 10^3 mg and 0.0743 kg.

Answer:

C.) 4,3

Step-by-step explanation:

The given system of equations is:

x + 3y = 15

4x + 2y = 30

The first equation can be rewritten as:

y = (15 - x)/3

Substituting this expression for y into the second equation gives:

Solving for x, we get:

x = 4

Substituting this value of x back into the first equation gives:

y = (15 - 4)/3 = 3

Therefore, the solution to the system of equations is (4,3).

According to Pythagoras, the square with the longest side is equal to the total of the squares with two sides. Therefore, the triangle in question has an acute angle of 28.07 degrees.

A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.

The Pythagorean theorem is satisfied by the triangle's dimension. As a result, the triangle has a right angle.

Answer:

A convex polygon's interior angle measure is given by the formula (n-2) * 180, where n is the number of sides of the polygon. So for a polygon with an interior angle sum of 900, we have (n-2) * 180 = 900. Solving for n, we get n = 5.

For a polygon with an interior angle sum of 2520, we have (n-2) * 180 = 2520. Solving for n, we get n = 14.

So the convex polygon with an interior angle sum of 900 is a pentagon, and the convex polygon with an interior angle sum of 2520 is a 14-gon.

• the opposite angles of a parallelogram are congruent.

Then

∠ 2 = ∠ 1

and

∠ 4 = ∠ 1

and

∠ 3 = ∠ 4

since ∠ 3 = ∠ 4 and ∠ 4 = ∠ 1 with ∠ 2 = ∠ 1 = ∠ 4

then

∠ 2 ≅ ∠ 3

By using the property of opposite angles of a parallelogram, we can say that ∠2 = ∠3.

A parallelogram is a special type of quadrilateral whose opposite sides are equal and parallel to each other. Another notable property of a parallelogram is that opposite angles are equal and sum of adjacent angles is 180 degrees.

Using the property that opposite angles of a parallelogram are equal,

In the parallelogram BEFG, ∠2 = ∠1 - equation 1

In the parallelogram DHJK, ∠4 = ∠3 - equation 2
