Answer:

(x - 2) • (x - 4) • (x - 8)

Step-by-step explanation:

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  +8  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 8 = 8  

Step-2 : Find two factors of  8  whose sum equals the coefficient of the middle term, which is   -6 .

     -8    +    -1    =    -9  

     -4    +    -2    =    -6    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  -2  

                    x2 - 4x - 2x - 8

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-4)

             Add up the last 2 terms, pulling out common factors :

                   2 • (x-4)

Step-5 : Add up the four terms of step 4 :

                   (x-2)  •  (x-4)

            Which is the desired factorization

______________

in 1 round distance covered = circumference

•radius = 35/100 m

•circumference = 2πr

=2×22/7×35/100

=44×5/100

= 220/100 m

220/100 m covered in 1 turn

1540m covered in 1540×100/220 = 700

hence ans is 700 turns

Answer:

728.85

Step-by-step explanation:

Surface area of a cylinder equation: A = 2πrh+2πr²

A = (2π(4)(25))+(2π(4²))

A = 728.85cm³

Answer:

A=2 B=1

Step-by-step explanation:

B is distributive because you have to foil the x out of the parenthesis

A is  because when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends.

Answer:

343

Answer:

Note that the ratio 12 to 3 is said to be equivalent to the ratio 4 to 1, that is 12:3 = 4:1.

Answer:

12:3 = 4.1

Step-by-step explanation:

12 to 3 is equal or equivalent to the ratio to 4 and 1 so the answer is 12:3 = 4.1

The given function for the height of the firework is a quadratic function

1. Time at which the firework reaches the maximum height is 1 seconds

2. The maximum height of the firework, is 25 yards

3. Time after which the firework will fall to the ground is (1 + √5) seconds

Reason:

The given function that represents the height of the fireworks with time is

presented as follows;

h(t) = -5·t² + 10·t + 20

1. The time at which the firework reaches its maximum height is given by

the maximum point of the given function as follows;

The x-value of the maximum point of a quadratic function is [tex]x = \dfrac{b}{2 \cdot a}[/tex]

Where;

a, and b, are the coefficient of x² and x, in the general form of a quadratic function f(x) = a·x² + b·x + c

By comparison, we have;

[tex]t = -\dfrac{10}{2 \times (-5)} = 1[/tex]

2. The maximum height is given by plugging in the value of t, at the maximum point into the given function as follows;

h(1) = -5×1² + 10×1 + 20 = 25

3 The time at which the firework will fall to the ground, is given by the zero of the function as follows;

When the firework falls to the ground, h(t) = 0 =  -5·t² + 10·t + 20

Dividing both sides by (-5) gives;

[tex]\dfrac{0}{-5} = \dfrac{ -5 \cdot t^2 + 10 \cdot t + 20}{-5} = t^2 - 2 \cdot t - 4[/tex]

t² - 2·t - 4 = 0

By the quadratic formula [tex]x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex], we get;

[tex]t = \dfrac{2\pm \sqrt{(-2)^{2}-4\times 1\times (-4)}}{2\times 1} = \dfrac{2\pm \sqrt{20}}{2\times 1} = \dfrac{2\pm 2 \times \sqrt{5}}{2\times 1} = 1 \pm \sqrt{5}[/tex]

Therefore;

Dilating a trapezoid involves changing its size.

The measure of side OL is 8

The given parameters are:

[tex]\mathbf{O'L' = 6}[/tex]

[tex]\mathbf{k = \frac 34}[/tex]

Side length O'L' is calculated using:

[tex]\mathbf{O'L' = OL \times k}[/tex]

Make OL the subject

[tex]\mathbf{OL = \frac{O'L'}{k}}[/tex]

So, we have:

[tex]\mathbf{OL = \frac{6}{3/4}}[/tex]

[tex]\mathbf{OL = 8}[/tex]

Hence, the measure of side OL is 8

Answer:

Step-by-step explanation:

Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure).

3x = 2x + 16

x = 16

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

check

3 * 16 = 2 * 16 + 16

48 = 48

the answer is good

Answer:

x=16

Step-by-step explanation:

Since both angles are vertically opposite, there fore they equal each other.

2x + 16 = 3x

Subtract 3x from both sides

2x - 3x + 16 = 3x - 3x

-x + 16 = 0

-x = 0-16

-x = -16 (Multiply both sides by -1)

x = 16

---------

3x 16 = 48

2*16 + 16 = 48

Answer:

Computer is $866

Printer is $433

Step-by-step explanation:

We can form two equations given our variables:

Let's assume the computer=C and the Printer=P.

1) C+P=1299

2) 2P=C

Now we just plug in the 2nd equation into the 1st.

(2P+P)=1299

3P=1299

P=1299/3

P=433

Now that we know the value of the printer, we can subtract that from the total price:

1299-433=866

C=866

Answer:

1/3

Step-by-step explanation:

1) Simplify 3/4t to 3t/4

3) Cancel 4

3t = 1

4) Divide both sides by 3

t = 1/3
