9 Write three fractions that are equivalent to
30.2% using denominators of 1,000, 100,
and 10.

Answer:

a) 18

b)x^2+10x+18

c)x^2 -6x+2

Step-by-step explanation:

This is a case of plugging in the value into f(x).

a) f(-8)= -8^2 + 6(-8) +2

f(-8)= 64 + (-48) +2

f(-8)=64 + (-46)

f(-8)=18

b)  f(x+2)= (x+2)^2+6(x+2)+2

So here I'll take a break to explain what's going on, because x+2 is a binomial meaning two terms and it is being squared I have to multiply the whole thing by itself. Meaning: (x+2) x (x+2), this is also known as foiling!! and for the next part its distributing 6 into x and 2.

    f(x+2)= x^2+4x+4+6x+12+2

I'll reorder it

 f(x+2)= x^2+4x+6x+12+2+4

    f(x+2)= x^2+10x+18

c) f(-x)= -x^2+6(-x) +2

f(-x)= x^2 -6x+2

Answer:

m<4 = 14

Step-by-step explanation:

m<4 = m<8

6x - 16 = 2x + 4

   +16          +16

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

6x = 2x + 20

-2x   -2x

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

4x = 20

/4     /4

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

x = 5

m<4 = 6x - 16

= 6(5) - 16

= 30 - 16

= 14

Thus, m<4 = 14

Answer:

m<4 = 14 --> final answer

The entries for Row 3 in step 3 are : 0, -1, -2, 1

R_{1} = Row1

R_{2} = Row  2

R_{3} = Row  3

For the third step, STEP 3 :

THE VALUE OF Row 3 is obtained thus :

[tex]R_{3} = R_{3} - 3R_{1}[/tex]

[tex]From \: step \: 1 : R_{1} = [1 1 1 0][/tex]

[tex]R_{1} = [1 1 1 0] \\  \\

[tex]R_{3} = [3 2 1 1]  \\  

\\ 3R_{1} = 3(1 1 1 0) = [3 3 3 0][/tex]

[tex]R_{3} - 3R_{1} \:  =

(3 - 3), (2 - 3), (1 - 3), (1 - 0) = (0, -1, -2, 1)[/tex]

Hence, the entry for Row 3 in step 3 will be :

(0, - 1, - 2, 1)

Step-by-step explanation:

SP=?

L%=15%

CP=$20

WE KNOW,

L= L%/100×CP

L= 15/100×20

L= 15/5

L= 3

NOW,

L = CP-SP

Or, 3 = 20 - SP

Or,SP= 20 -3

SP=RS 17

Answer:

  {(1, 2), (3, 4)}

Step-by-step explanation:

If you want both the relation and its inverse to be functions, there can be no repeated x-values, and no repeated y-values.

In the above pair of points, I have avoided duplicates by making all of the values different. That is not necessary, but it satisfies this problem easily.

your answer is 1/36 because if you spin once it would be 1/18 and if spin x2 the answer would be 1/36

Answer:

[tex]x^2-6x+9[/tex]

Step-by-step explanation:

Say you have a function [tex]f(x)=x+1[/tex]. If you wanted to find f(3), you would replace the number in the parentheses, in this case 3, with x, to get [tex]f(3)=3+1=4.[/tex] When combining functions, you should do the same thing.

Here, we have [tex]f(x)=x^2.[/tex] We want to find f(g(x)). So, you should replace x in the function f(x) with the function g(x). [tex]g(x)=x-3.[/tex] So, f(g(x)) would equal [tex](x-3)^2[/tex], which equals [tex]x^2-6x+9[/tex].

Every problem has a solution .Lets solve it .

Here given that

[tex]\\ \sf\longmapsto x=\dfrac{y}{5}[/tex]

[tex]\\ \sf\longmapsto y=5x\dots(1)[/tex]

Now

As its a triangle

[tex]\\ \sf\longmapsto 90+x+y=180[/tex]

[tex]\\ \sf\longmapsto 90+x+5x=180[/tex]

[tex]\\ \sf\longmapsto 6x+90=180[/tex]

[tex]\\ \sf\longmapsto 6x=180-90[/tex]

[tex]\\ \sf\longmapsto 6x=90[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{90}{6}[/tex]

[tex]\\ \sf\longmapsto x=15[/tex]

We need not to find y

See the marked angle and x are supplementary angles hence there sum will be 180

[tex]\\ \sf\longmapsto x+15=180[/tex]

[tex]\\ \sf\longmapsto x=180-15[/tex]

[tex]\\ \sf\longmapsto x=165[/tex]

The required angle is 165°.

Lets find f(n) formula

[tex]\boxed{\sf f(n)=\dfrac{1680}{n}}[/tex]

Now

[tex]\\ \sf\longmapsto f(10)=\dfrac{1680}{10}=168[/tex]

[tex]\\ \sf\longmapsto f(12)=\dfrac{1680}{12}=140[/tex]

[tex]\\ \sf\longmapsto f(16)=\dfrac{1680}{16}=105[/tex]

[tex]\\ \sf\longmapsto f(14)=\dfrac{1680}{14}=120[/tex]
