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

Explanation:

Apply difference of cubes formula: [tex]\bold{x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)}[/tex]

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

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

2² = 4

Answers

Answer:

slope = [tex]-\frac{1}{8}[/tex]

Step-by-step explanation:

Use the slope formula given in the question to solve for the slope. The [tex]m[/tex] is the variable representing the slope. The [tex]x_1[/tex] and [tex]y_1[/tex] values are x and y values of one point. The [tex]x_2[/tex] and [tex]y_2[/tex]  are x and y values of another point.

So, use the x and y values of the points given and substitute them in the correct order into the formula:

[tex]m = \frac{(7)-(9)}{(10)-(-6)}\\m = \frac{7-9}{10+6} \\m = \frac{-2}{16} \\m = -\frac{1}{8}[/tex]

Thus, the slope is [tex]-\frac{1}{8}[/tex].

A-line includes the points (8,9) and (9,1). What is its equation in point-slope form?

Answers

Answer:

[tex]y-(9)=(-8)(x-8)\\[/tex]

Step-by-step explanation:

[tex](x_1, y_1) = (8, 9)\\(x_2, y_2) = (9,1)\\[/tex]

Step one: Find the slope (m)

[tex]slope=m=\frac{rise}{run} =\frac{y_2-y_1}{x_2-x_1} = \frac{1-9}{9-8} =\frac{-8}{1} =-8[/tex]

Step two: Plug your known values into the point-slope equation

[tex]m=-8\\y_1=9\\x_1=8\\[/tex]

Point-slope form is [tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(9)=(-8)(x-8)\\[/tex]

If you want to convert point-slope form to general form, isolate for y.

[tex]y-9=-8x+64\\y=-8x+73[/tex]

A certain forest covers an area of 4800 km^2 . Suppose that each year this area decreases by 5.25% . What will the area be after 6 years? Use the calculator provided and round your answer to the nearest square kilometer.

Answers

Answer:

the area after 6 years is  3,473 km^2

Step-by-step explanation:

The computation of the area after 6 years is as follows:

= Area × (1 - decreased percentage)^number of years

= 4,800 km^2 × (1 - 5.25%)^6

= 4,800 km^2 × 0.9475^6

= 3,473 km^2

Hence, the area after 6 years is  3,473 km^2

The perimeter of a right-angled triangle is 96 cm.
The lengths of its sides are in the ratio 6:8:10
Work out the area of the triangle in cm”.
B x W x = 2
Total marke: 4

Answers

Answer:

[tex]A=384\ cm^2[/tex]

Step-by-step explanation:

Let the sides of a triangle be 6x,8x and 10x.

Perimeter of the triangle, P = 96 cm

We need to find the area of the triangle.

P = sum of all sides

6x+8x+10x = 96

24x = 96

x = 4

Sides are :

6x = 6(4) = 24 cm

8x = 8(4) = 32 cm

10x = 10(4) = 40 cm

Area,

[tex]A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 24\times 32\\A=384\ cm^2[/tex]

So, the area of the triangle be [tex]384\ cm^2[/tex].

What is the mean of the values in the dot plot?



Enter your answer in the box.

Answers

Answer:

The mean is 46.

Step-by-step explanation:

To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.

40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50

Multiply what's in the parentheses.

40 + 82 + 45 + 96 + 147 + 50

Add, going from left to right

122 + 45 + 96 + 147 + 50

167 + 96 + 147 + 50

263 + 147 + 50

410 + 50

460

Now, divide that by how many dots there were (10).

460/10

The mean of the values in this dot plot is 46.

Answers

Answer:2

Step-by-step explanation:

For line y = 9x, m = 9 and c = 0

What is the slope-intercept form of the line?

"y = mx + c, where m is the slope of the line and c is the y-intercept of the line."

What is slope of the line?

"It is the change in y coordinate with respect to the change in x coordinate."

What is y-intercept?

"It is a point at which a line intersects the Y-axis."

For given question,

We have been given an equation of line y = 9x

By comparing above equation of line with the slope-intercept form of line,

m = 9 and c = 0

This means the slope of the line y = 9x is 9 and the y-intercept is 0

Therefore, for line y = 9x, m = 9 and c = 0
