Answer:

The y-intercept is where an equation's graph hits the y-axis. It represents the constant value, when x=0, the intercept is the constant

Step-by-step explanation:

The y-intercept indicates the vertical position where the line or curve intersects the y-axis

The y-intercept refers to the point where a line or curve intersects the y-axis on a graph.

It is the value of the dependent variable (y) when the independent variable (x) is equal to zero.

In the equation of a line in slope-intercept form (y = mx + b), where m represents the slope of the line and b represents the y-intercept, the y-intercept is the constant term (b).

The y-intercept represents the value of the dependent variable (y) when the independent variable (x) is not present or equal to zero.

It is the initial value or starting point of the function or graph.

Answer:

Step-by-step explanation:

The complete factorized form for the given expression is [tex]\left(9 x^{4}+1\right)\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)[/tex]

Step-by-step explanation:

Step 1: Given expression:

              [tex]81 x^{8}-1[/tex]

Step 2: Trying to factor as a Difference of Squares

Factoring [tex]81 x^{8}-1[/tex]

As we know the theory that the difference of two perfect squares, [tex]A^{2}-B^{2}[/tex]  can be factored into (A+B) (A-B)

from this, when analysing, 81 is the square of 9, [tex]x^{8}[/tex] is the square of [tex]x^{4}[/tex]. Hence, we can write the given expression as,

            [tex]\left(9 x^{4}\right)^{2}-1^{2}[/tex]

By using the theory, we get

           [tex]\left(9 x^{4}+1\right)\left(9 x^{4}-1\right)[/tex]

Again, we can further factorise the term [tex]\left(9 x^{4}-1\right)[/tex]

[tex]9 x^{4}[/tex] is the square of [tex]3 x^{2}[/tex]. Therefore, it can be expressed as below

           [tex]\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)[/tex]

Now, we can not factorise further the term [tex]\left(3 x^{2}-1\right)[/tex]. Because it will come as [tex]\sqrt{3} x[/tex] (3 is not a square term). Thereby concluding that the complete factorisation for the given expression is [tex]\left(9 x^{4}+1\right)\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)[/tex]

BOTH TRIANGLES ARE SIMILAR BY THE AA SIMILARITY POSTULATE.

In first triangle:

Remaining angle = 180° - (70° + 30°)= 80°

In second triangle:

Remaining angle = 180° - (80° + 30°)= 70°

Hence, all the angles of first triangle are congruent to the corresponding angles of the second triangle.

Thus, both the triangles are similar by

Answer:

see explanation

Step-by-step explanation:

Using the Cosine rule

a² = b² + c² - 2abcosA ← Rearranging for cosA gives

cosA = [tex]\frac{b^2+c^2-a^2}{2ab}[/tex]

(a)

let a = 10, b = 7, c = 8 and A = α, then

cosα = [tex]\frac{7^2+8^2-10^2}{2(7)(8)}[/tex] = [tex]\frac{49+64-100}{112}[/tex] = [tex]\frac{13}{112}[/tex], thus

α = [tex]cos^{-1}[/tex]( [tex]\frac{13}{112}[/tex] ) ≈ 83° ( to the nearest degree )

(b)

let the angle opposite side 7 be x

Using the Sine rule

[tex]\frac{10}{sin83}[/tex] = [tex]\frac{7}{sinx}[/tex] ( cross- multiply )

10sinx = 7sin83 ( divide both sides by 10 )

sinx = [tex]\frac{7sin83}{10}[/tex] , thus

x = [tex]sin^{-1}[/tex] ( [tex]\frac{7sin83}{10}[/tex] ) = 44°

The third angle can be found using the sum of angles in a triangle

third angle = 180° - (83 + 44)° = 180° - 127° = 53°

The 3 angles are 83°, 44°, 53°

Final answer:

Multiplying the dimensions of a rectangle by 3 increases its area by a factor of 9, which is the square of 3. The area of the rectangle goes from 14 cm^2 to 126 cm^2.

Explanation:

When the dimensions of a rectangle are multiplied by a certain factor, the area of the rectangle is affected by the square of that factor. Initially, the area of a 7-cm by 2-cm rectangle is 14 cm2. When the dimensions are each multiplied by 3, the new dimensions become 21 cm by 6 cm. Therefore, the new area is 21 cm  imes 6 cm = 126 cm2. The area scales in proportion to the square of the linear dimensions. If we compare the new area to the old area, we see that 126 cm2 / 14 cm2 equals 9, meaning the area has increased by a factor of 9, which is 32, since we multiplied the dimensions by 3. This principle applies generally: when a rectangle's dimensions are scaled by a factor, its area is scaled by the square of that factor.

To determine how many ways to paint the buildings, we consider the choices for each building sequentially, considering the constraints. There are either 36 or 24 combinations, depending on the colors chosen for the first and last buildings. A step-by-step count confirms this range of possibilities.

A systematic approach gives us the general formula: 4 choices for the first building × 3 choices for the second building × 3 choices for the third building × (2 or 3) choices for the fourth building, depending on the first color chosen. This results in a total of 36 or 24 possible combinations, depending on the first and last color's relationship. A careful count avoiding the restrictions on the colors confirms this.

Answer:

The volume of the actual house is 1,324.94 cubic meters

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Height of the scale model = 53 cm

Height of the actual house = 624 cm

Scale of the model = 642/53 = 11.77

Volume of the scale model = 0.8125 cubic meters

2. What is the volume of the house?

For answering the question we have to find the width and the length of the model, then use the scale of the model for calculating the volume of the actual house, this way:

Volume of the scale model = 0.8125 cubic meters

Area of the scale model = Volume of the model/Height of the model

Area of the scale model = 0.8125/0.53

Area of the scale model = 1.533 square meters

Area of the scale model = Length * Width

Area of the scale model = 1.533 * 1

Now, we can calculate, the measurements of the house to calculate its volume:

Height of the actual house = 6.24 meters

Length of the actual house = 1.533 * 11.77 = 18.04 meters

Width of the actual house = 1 * 11.77 = 11.77 meters

Volume of the actual house = 6.24 * 18.04 * 11.77

Volume of the actual house = 1,324.94 cubic meters

Write the ratio as a fraction in simplest form

Part 1) 15 girls to 6 boys

we know that

To find out the ratio, divide the number of girls by the number of boys

so

[tex]\frac{15}{6}[/tex]

Simplify

Divide by 3 both numerator and denominator

[tex]\frac{5}{2}\ \frac{girls}{boys}[/tex]

Part 2) 24 plays for 3 teams

we know that

To find out the ratio, divide the number of plays by the number of teams

so

[tex]\frac{24}{3}[/tex]

Simplify

Divide by 3 both numerator and denominator

[tex]\frac{8}{1}\ \frac{plays}{team}[/tex]

Final answer:

To simplify the ratios 15 girls : 6 boys and 24 plays : 3 teams, find the greatest common factor and divide both parts of the ratio by it, resulting in the simplest forms  rac{5}{2} and 8, respectively.

Explanation:

To write the ratios as fractions in simplest form for the given scenarios:

For the ratio of 15 girls to 6 boys, the fraction would be  rac{15}{6}. To simplify, divide both the numerator and the denominator by their greatest common factor (GCF), which is 3. Thus, the simplest form is  rac{15 \/ 3}{6 \/ 3} =  rac{5}{2}.

For the ratio of 24 plays for 3 teams, the fraction is  rac{24}{3}. Again, to simplify, divide both the numerator and the denominator by the GCF, which is 3 in this case. The simplest form is  rac{24 \/ 3}{3 \/ 3} =  rac{8}{1}, which can also be written simply as 8 since a denominator of 1 implies the value is a whole number.
