Three out of seven soccer players wore headbands in a soccer league. a. Write the ratio of soccer players who wore headbands to soccer players who did not. b. If there were 36 players in the league who did not wear headbands, how many players were in the league?

Answer:

Equation: [tex]x=9[/tex]

Step-by-step explanation:

First graph the points on the coordinate plane, then find the x and y intersections and the slope. Since the slope is 0, and the x intersection is 9, you get [tex]x=9[/tex].

Answer:

40 percent

Step-by-step explanation:

60 plus 60 is 120 and take 20 from 60 and get 40 so 40 times 3 equals 123 so 40 percent

[tex]g( \: f(x) \: ) = x[/tex]

And

[tex]f( \: g(x) \: ) = x[/tex]_________________________________

So :

[tex]g(x) = {f}^{ - 1}(x) [/tex]

And

[tex]f(x) = {g}^{ - 1}(x) [/tex]

_________________________________

So to find g(x) , we must find the inverse of f(x) .

Let's do it .....

[tex]f(x) = 8 {x}^{3} + 1 [/tex]

[tex]y = 8 {x}^{3} + 1 [/tex]

Subtract the sides of the equation minus 1

[tex]y - 1 = 8 {x}^{3} [/tex]

Divided the sides of the equation by 8

[tex] \frac{y - 1}{8} = {x}^{3} \\ [/tex]

From the sides of the equation, we take the radical with interval 3

[tex] \sqrt[3]{ \frac{y - 1}{8} } = x \\ [/tex]

[tex] \sqrt[3]{ \frac{1}{8}(y - 1) } = x \\ [/tex]

[tex] \frac{1}{2} \sqrt[3]{y - 1} = x \\ [/tex]

[tex] \frac{ \sqrt[3]{y - 1} }{2} = x \\ [/tex]

So ;

[tex] {f}^{ - 1}(x) = \frac{ \sqrt[3]{x - 1} }{2} \\ [/tex]

Now we find g(x) which is :

[tex]g(x) = \frac{ \sqrt[3]{x - 1} }{2} \\ [/tex]

If f(g(x)) = x and g(f(x)) = x , than  [tex]\rm g(x) = \sqrt[3]{\dfrac{x-1}{8}}[/tex] and this can be calculated by finding the inverse of the given function f(x).

Given :

Given that f(g(x)) = x it means that:

[tex]\rm g(x) = f^{-1}(x)[/tex]

It is also given that g(f(x)) = x that means:

[tex]\rm f(x) = g^{-1}(x)[/tex]

Now, the inverse of f(x) is given by the following calculation:

[tex]\rm f(x) = 8x^3+1[/tex]

Now, replace f(x) with y in the above equation.

[tex]y = 8x^3+1[/tex]

Now, replace y with x and x with y and evaluate 'y'.

[tex]x = 8y^3 +1[/tex]

[tex]\sqrt[3]{\dfrac{x-1}{8}}=y[/tex]

Now, replace y with [tex]\rm f^{-1}(x)[/tex] in the above equation.

[tex]\rm f^{-1}(x) = \sqrt[3]{\dfrac{x-1}{8}}[/tex]

[tex]\rm f^{-1}(x) = \sqrt[3]{\dfrac{x-1}{8}} = g(x)[/tex]

======================================================

Explanation:

In any quadrilateral, the four angles always add to 360

P+Q+R+S = 360

x+5x+x+5x = 360

12x = 360

x = 360/12

x = 30

This means

P = R = x = 30

Q = S = 5x = 5*30 = 150

So, P+Q+R+S = 30+150+30+150 = 360 which helps confirm the answer.

Answer:

x = 30

Step-by-step explanation:

the sum of all angles is 360

the picture shows that the sum equals 12x

12x=360

x= 360/12

x = 30

Let's see what to do buddy...

________________________________

If 99 & 100 are in Degree

_________________________________

STEP (1)

The angles 99 and 100 are in the second quarter of the trigonometric circle.

The cosine is negative in the second quarter.

To make things easier, we can use angle conversion.

Look :

[tex]we \: know \: that \: 100 = 90 + 10[/tex]

[tex]also \: we \: know \: 99 = 90 + 9[/tex]

So :

[tex] \cos(100) = \cos(90 + 10) = \cos( \frac{\pi}{2} + 10 ) \\ [/tex]

[tex] \cos(99) = \cos(90 + 9) = \cos( \frac{\pi}{2} + 9 ) \\ [/tex]

_________________________________

STEP (2)

Well now we have to do the arc deletion.

To remove the arc, we remove π/2 from the arc.

Remember that every time we remove π/2 from the arc, the trigonometric ratio changes.

That is, if it is a sine, it becomes a cosine, and if it is a cosine, it becomes a sine.

Or if it is a tangent, it becomes a cotangent, and if it is a cotangent, it becomes a tangent.

[tex]in \: second \: quarter \: cosine \: is \: negative \\ \\ \cos( \frac{\pi}{2} + 10 ) = - \sin(10) = - 0.173 [/tex]

[tex] \cos( \frac{\pi}{2} + 9 ) = - \sin(9) = - 0.156 \\ [/tex]

_________________________________

STEP (3)

[tex] \cos(100) - \cos(99) = \\ - \sin(10) - ( - \sin(9) \: ) = \\ - 0.173 - ( - 0.156) = \\ - 0.173 + 0.156 = - 0.017 [/tex]

And we're done here.

_________________________________

If 99 & 100 are in Radian

_________________________________

STEP (1)

First we need to know how many degrees 1 radian is.

The following equation is used to convert degrees to radians or radians to degrees.

[tex] \frac{degree}{180} = \frac{radian}{\pi} \\ [/tex]

So we have :

[tex] \frac{d}{180} = \frac{1}{\pi} \\ [/tex]

Multiply the sides of the equation by 180 :

[tex]d = \frac{180}{\pi} = \frac{180}{3.14} = 57.32 \\ [/tex]

So 1 radian is approximately equal to 57 degrees.

And we have :

[tex]100 \: rad \: = 100 \times 57 = 5700 \: deg \\ \\ 99 \: rad \: = 99 \times 57 = 5601 \: deg[/tex]

_________________________________

STEP (2)

Let's move on to deletion.

Look : 5700° = 15 × 360° + 300°

and : 5601° = 15 × 360° + 201°

We know π rad = 3.14 × 57 = 180° deg

So 2π rad = 2 × 180 = 360 ° deg

Then :5700 = 15 × 2 π + 300° = 30 π + 300°

and :5601 = 15 × 2 π + 201° = 30 π + 201°

Remember that deleting 2π is unconditional.

[tex] \cos(30\pi + 300) = \cos(300) = \cos(360 - 60) = \cos(2\pi - 60) = \cos( - 60) = \\ cosine \: eat \: negative \\ \cos( - 60) = \cos(60) = \frac{1}{2} [/tex]

[tex] \cos(30\pi + 201) = \cos(201) = \\ \cos(180 + 21) = \cos(\pi + 21) = \\ - \cos(21) = - 0.933 [/tex]

[tex] \frac{1}{2} - ( - 0.933) = 0.500 + 0.933 = 1.433[/tex]

And we're done.

Thanks for watching buddy good luck.

Answer:

y = 3/4x + 1/2

Step-by-step explanation:

We can use the formula [ y2-y1/x2-x1 ] to solve for the slope.

-4-5/-6-6

-9/-12

9/12

3/4

Find the y-intercept.

y = 3/4x + b

5 = 3/4(6) + b

5 = 4.5 + b

0.5 = b

y = 3/4x + 1/2

Best of Luck!

First of all, Let's find the slope because we need it on the formula for finding the y-intercept.

From the points given in the question,

Plugging in the above formula,

➝ m = -4 - 5 / -6 - 6

➝ m = -9 / -12

➝ m = 3/4

Now finding the y-intercept[tex]:[/tex]

➝ y = mx + b

And if we put in the values from our first point (6, 5) we get

➝ 5 = 3/4 (6) + b

➝ 5 = 9/2 + b

➝ b = 5 - 9/2

➝ b = 1/2

Required equation of the line:

➝ y = 3/4x + 1/2

Answer:

x = - 2, - 3

Step-by-step explanation:

Given

- 3x + 4 ≥ 9 ( subtract 4 from both sides )

Answer:

x > -1

Step-by-step explanation:

Isolate the variable, x. Treat the > sign like an equal sign, what you do to one side, you do to the other.

Subtract 5 from both sides:

x + 5 (-5) > 4 (-5)

x > 4 - 5

x > -1

x > -1 is your answer.

Answer:

x > -1

Step-by-step explanation:

Step 1: Write inequality

The following statement should be a(n) inductive reasoning.

Step-by-step explanation:

inductive Reasoning: Has observations and draws a conclusion from it.

As seen in the statement:

The hypothesis is: Ever quiz has been easy.

While the conclusion is: Therefore, the test will be easy.

Their observation was that every quiz was easy, so they concluded that the test would be too.
