Answer:

20

Step-by-step explanation:

Took the cumulative exam on Edge

The value of y in the given similar triangles is 20.

Two triangles are said to be similar if their corresponding angles are congruent to each other and the corresponding sides are in equal ratios.

Given are two triangles, we need to find the value of y so that the triangles be similar by SSS rule,

If the figures are similar by SSS Similarity Theorem, then the ratio of its corresponding sides must be proportional,

So,

14/28 = 10/y

y = 20

Hence, the value of y in the given similar triangles is 20.

[tex]\huge\boxed{Answer\hookleftarrow}[/tex]

Given,

[tex]3x - 2y = 5[/tex]

[tex]xy = - 2[/tex]

Now,

[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ [/tex]

Use the algebraic identity ⇻ (a - b)² = a² - 2ab + b²

[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ 3x {}^{2} - 2 \times 3x \times 2y + 2y {}^{2} = 5 {}^{2} \\ 9 {x}^{2} - 12xy + 4y {}^{2} = 25 \\9x {}^{2} + 4y {}^{2} = 25 + 12xy \\ 9x {}^{2} + 4 {y}^{2} - 1 = 24 + 12xy[/tex]

✐ So, the value of 9x² + 4y² - 1 is 24 + 12xy

Now,

xy = - 2

So, 12xy = 12 × - 2 = - 24

•°• 24 + 12xy

= 24 + (-24)

= 24 - 24

Answer:

6 x 4 = 24, 24 x 2 = 48

7 x 6 = 42

7 x 4 = 28, 28 x 2 = 56

6 x 4 x 1/2(basically just dividing by 2) = 12, 12 x 2(two triangles) = 24

5 x 5 = 25, 25 x 2 = 50

Add given areas:

48 + 42 + 56 + 24 + 50 = 220 ft^2 is your answer.

7a* Consider the distance is x

2/3x = 240

x = 360

The Distance between two points = 360 Km

7b* Consider the average speed at 2/3 distance was V

(45+V)/2 = 54

45+V = 108

V= 108-45= 63km/hr

The average speed for the last 2/3 trip was 63 km/hr

The factor form of expression (b³ - 1,000) will be;

⇒ (b - 10) (b² + 10b + 100)

What is mean by Factor?

A number or an algebraic expression that divides the another number or algebraic expression is called the factor of same number.

Given that;

The algebraic expression is;

⇒ b³ - 1,000

Now, Solve the expression for the factor form as;

Since, The formula is;

a³ - b³ = (a - b) (a² + ab + b²)

Hence, we factor the expression  b³ - 1,000 with the help of above formula as;

⇒ b³ - 1,000

⇒ b³ - 10³

⇒ (b - 10) (b² + b × 10 + 10²)

⇒ (b - 10) (b² + 10b + 100)

Thus,  b³ - 1,000 =  (b - 10) (b² + 10b + 100)

Therefore,

The factor form of expression (b³ - 1,000) will be;

⇒ (b - 10) (b² + 10b + 100)

Answer:

20,000 per sq. km.

Step-by-step explanation:

In this question, the variable k represents the total number of people in a single square km. Since we are provided both the total number of the population and the total square kilometers of the land, we can calculate the value of k by dividing the population size by the total land. Therefore, the calculation would be the following...

[tex]\frac{10,400,000 people}{520km^{2} }[/tex] = k

20,000 per sq. km. = k

Finally, we can see that the value of k is 20,000 per sq. km.

C = 2 * pi *9

C = 18 pi

This is a semicircle which is 1/2 of a circle

Take 1/2 of the circumference

1/2 C = 1/2 ( 18 pi)

1/2 C = 9 pi

Step-by-step explanation:

1(x+3)^2-1=0

Add 1 to each side

1(x+3)^2-1+1=0+1

(x+3)^2=1

Take the square root of each side

sqrt((x+3)^2)=sqrt(1)

x+3 = ±1

x+3 = 1    x+3 = -1

Subtract 3 from each side

x+3-3 = 1-3    x+3-3 = -1-3

x = -2     x=-4

Problem 3

-------------------------

Explanation:

Two points from the graph are (10,2) and (20,4)

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (4-2)/(20-10)

m = 2/10

m = 1/5

The slope of the graph is 1/5.

Do the same for two points from the table. I'll use the first two rows

m = (y2-y1)/(x2-x1)

m = (4-2)/(10-5)

m = 2/5

The slope of the table is 2/5.

Subtract the two slopes to wrap things up:

2/5 - 1/5 = (2-1)/5 = 1/5
