the answer is 11

Answer:

d

Step-by-step explanation:

Answer:

9/16

Step-by-step explanation:

First, note that 10000 multiplied by .5625 will get rid of the decimal point. Therefore, make a fraction where the numerator is .5625 times 10000 and denominator is 10000 like this:

.5625 x 10000

10000

Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:

5625 /10000

The greatest common factor of 5625 and 10000 is 625, which means you can divide the numerator and denominator by 625 and keep the same value:

5625 ÷ 625 /10000 ÷ 625

And when calculating the numerator and denominator in our fraction above, we get .5625 as a fraction in the simplest form possible:

 .5625  =  

9 /16

Answer:

308

Step-by-step explanation:

Hello the answer is

14 times 44 = 616

then do 616 divided by 2 because half = 308

Pulling out like terms

2.1     Pull out like factors :

  x9 - x6 - x3  =   x3 • (x6 - x3 - 1)

Trying to factor by splitting the middle term

2.2     Factoring  x6 - x3 - 1

The first term is,  x6  its coefficient is  1 .

The middle term is,  -x3  its coefficient is  -1 .

The last term, "the constant", is  -1

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

Step-2 : Find two factors of  -1  whose sum equals the coefficient of the middle term, which is   -1 .

     -1    +    1    =    0

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 x3 • (x6 - x3 - 1)

At the coordinate of -9, the value of the function g(-9) will be 1.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that in the graph the function is varies with the value of the coordinates, at the value of -9 the solution for the function g(-9) will be equal to 1

g(-9) = 1

Hence, the value of the function will be 1.

Hannah and Omar Only used a formula that will help them prove the relationship.

A line drawn parallel to one side of a Δ divides the other two sides in the same ratio.

Given

To prove that DE divides AB and AC proportionally.

Construction: If DE is not parallel to BC, draw DF meeting AC at F.

Proof: In ΔABC, let DF || BC

[tex]\rm \dfrac{AD}{DB}=\dfrac{AC}{FC}\\\\[/tex]

A line drawn parallel to one side of a Δ divides the other two sides in the same ratio.

Answer:

The new set of coordinates are [tex]E'(x,y) = (-6,-12)[/tex], [tex]F'(x,y) = (12,-30)[/tex], [tex]G'(x,y) = (30,-6)[/tex] and [tex]H'(x,y) = (6,6)[/tex].

Step-by-step explanation:

Vectorially speaking, dilation can be defined by this equation:

[tex]D'(x,y) = O(x,y) +k\cdot (D(x,y)-O(x,y))[/tex] (1)

Where:

[tex]O(x,y)[/tex] - Center of dilation.

[tex]D(x,y)[/tex] - Original point.

[tex]k[/tex] - Scale factor.

[tex]D'(x,y)[/tex] - Dilated point.

Let suppose that center of dilation is located at origin, we determine the new set of coordinates below:

[tex]E'(x,y) = O(x,y) +k\cdot (E(x,y)-O(x,y))[/tex]

[tex]E'(x,y) = (0,0) +6\cdot (-1,-2)[/tex]

[tex]E'(x,y) = (-6,-12)[/tex]

[tex]F'(x,y) = O(x,y) + k\cdot (F(x,y)-O(x,y))[/tex]

[tex]F'(x,y) = (0,0) +6\cdot (2,-5)[/tex]

[tex]F'(x,y) = (12,-30)[/tex]

[tex]G'(x,y) = O(x,y) + k\cdot (G(x,y)-O(x,y))[/tex]

[tex]G'(x,y) = (0,0) + 6\cdot (5,-1)[/tex]

[tex]G'(x,y) = (30,-6)[/tex]

[tex]H'(x,y) = O(x,y) +k\cdot (H(x,y)-O(x,y))[/tex]

[tex]H'(x,y) = (0,0) + 6\cdot (1,1)[/tex]

[tex]H'(x,y) = (6,6)[/tex]

The new set of coordinates are [tex]E'(x,y) = (-6,-12)[/tex], [tex]F'(x,y) = (12,-30)[/tex], [tex]G'(x,y) = (30,-6)[/tex] and [tex]H'(x,y) = (6,6)[/tex].

Answer:

[tex]\$527.2[/tex]

Step-by-step explanation:

[tex]r_i[/tex] = Inner radius

Inner circumference = 4.5 m

[tex]2\pi r_i=4.5\\\Rightarrow r_i=\dfrac{4.5}{2\pi}\\\Rightarrow r_i=\dfrac{2.25}{\pi}[/tex]

[tex]r_o[/tex] = Outer radius

Outer circumference = 4.6 m

[tex]2\pi r_o=4.6\\\Rightarrow r_o=\dfrac{4.6}{2\pi}\\\Rightarrow r_o=\dfrac{2.3}{\pi}[/tex]

h = Height of cylindrical pipe = 8 m

Total surface area to be painted

[tex]s=\pi r_i^2h+\pi r_o^2h\\\Rightarrow s=\pi h(r_i^2+r_o^2)\\\Rightarrow s=\pi\times 8((\dfrac{2.25}{\pi})^2+(\dfrac{2.3}{\pi})^2)\\\Rightarrow s=26.36\ \text{m}^2[/tex]

Cost of painting 1 square meter is 20

Cost of painting the inner and outer surfaces is [tex]20\times 26.36=\$527.2[/tex]

The total cost painting the surfaces is [tex]\$527.2[/tex].

Answer:

5,040

Step-by-step explanation:

10x9x8x7 = 5,040

Using the permutation formula, it is found that 5040 passwords are possible.

The order is important, as 1234 is a different password than 2134, for example, hence the permutation formula is used to solve this question.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, 4 digits are taken from a set of 10, hence:

[tex]P_{(10,4)} = \frac{10!}{6!} = 5040[/tex]

5040 passwords are possible.
