Answer:

y = 8/27

Step-by-step explanation:

given

x = 7

y = 4x*y - 4(2)

y = 4*7*y - 8

y = 28y - 8

8 = 28y - y

8 = 27y

8/27 = y

to prove

y = 4x*y - 4(2)

8/27 = 4*7*y - 8

8/27 = 28*8/27 - 8

8/27 = 224/27 - 8

8/27 = 224 - 27*8/27

8/27 = 8/27

hence it is proved that y is 8/27 .

Step-by-step explanation:

Perhaps you're stuck because it is too simple. If any value in the x-column is repeated, the relation is not a function.

Of the two relations shown, the first is not a function (x=3 is repeated), and the second one is a function (all the x-values are different).

Answer:

The coefficient of variation after the tax is imposed is 0.033

Step-by-step explanation:

Given

[tex]\mu =1000[/tex] --- mean

[tex]\sigma^2 = 1200[/tex] --- variance

[tex]tax = 10\%[/tex]

Required

The coefficient of variation

The coefficient of variation is calculated using:

[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]

After the tax, the new mean is:

[tex]\mu_{new} = \mu * (1 + tax)[/tex]

[tex]\mu_{new} = 1000 * (1 + 10\%)[/tex]

[tex]\mu_{new} = 1100[/tex]

And the new variance is:

[tex]\sigma^2_{new} = \sigma^2 * (1 + tax)[/tex]

[tex]\sigma^2_{new} = 1200 * (1 + 10\%)[/tex]

[tex]\sigma^2_{new} = 1320[/tex]

So, we have:

[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]

[tex]CV = \frac{\sqrt{1320}}{1100}[/tex]

[tex]CV = \frac{36.33}{1100}[/tex]

[tex]CV = 0.033[/tex]

Answer:

π in²

Step-by-step explanation:

We'll begin by calculating the radius of the circle. This can be obtained:

Area of sector (A) = 4π in²

Angle (θ) = 120 °

Radius (r) =?

The radius of the circle can be obtained by using the formula for calculating the area of a sector. This is illustrated below:

A = θ/360 × πr²

4π = 120/360 × πr²

4π = ⅓ × πr²

Cross multiply

3 × 4π = πr²

12π = πr²

Divide both side by π

r² = 12π / π

r² = 12

Take the square root of both side

r = √12 in

Thus, the radius is √12 in.

Finally, we shall determine the area of the sector created by 30 °. This can be obtained as follow:

Radius (r) = √12 in

Angle (θ) = 30 °

Area of sector (A) = ?

A = θ/360 × πr²

A = 30/360 × π(√12)²

A = 1/12 × 12π

A = π in²

Therefore, the area of the sector created by 30 ° us π in².

Step-by-step explanation:

as far as I can tell the steps between the given numbers are

-1

+4

-27

+16

1 can be expressed as 1³

4 can be expressed as 2²

27 can be expressed as 3³

16 can be expressed as 4²

my best guess is that next one is minus 5³ = -125

edit: technically the given steps can be expressed as

(-1)³

(-2)²

(-3)³

(-4)²

somewhat nicer pattern there

Given :

An airplane flying at an altitude of 37,000 feet is still A horizontal distance of 100 miles (100 miles = 5280 ft) from the airport.

To Find :

What angle of depression does the airplane need to use to reach the runway?

Solution :

Let, angle of depression is [tex]\theta[/tex] .

So,

[tex]tan\ \theta = \dfrac{ Altitude \ in \ which \ plane \ is \ flying}{Horizontal \ Distance}\\\\tan \ \theta = \dfrac{37000}{5280}\\\\tan \ \theta = 7.00\\\\\theta = tan^{-1} 7\\\\\theta = 81.87^o[/tex]

Hence, this is the required solution.

Answer:

  x = 48

Step-by-step explanation:

The sum of the angles in a pentagon is 540°, so you have ...

  90° +100° +110° +2x° +3x° = 540°

  5x = 240 . . . . . . . divide by °, subtract 300

  x = 48 . . . . . . . . . divide by 5

The required value of P would be 64 for the given linear relationship.

A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.

Given that P varies inversely with the square of Q

P = k/Q²

As per the question, if Q is 8 and P is 9,

So 9 = k/8²

⇒ 9 = k/64

Apply cross-multiplication operation,

⇒ k = 576

If Q is 3, then

⇒ P = 576/3²

⇒ P = 576/9

Apply division operation, and we get

⇒ P = 64

Thus, the required value of P would be 64.

Answer:

the value of x = 3 and y = 3

Step-by-step explanation:

2x + y = 9 ------------ (1)

-2y -2x = -22 ------------ (2)

Subtract (1) from (2)

-2x -2y = -22

2x + y = 19

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

       -y = -3

        y = 3

Put the value of y in equation 1

2x + y = 9

2x + 3 = 9

2x = 9 - 3

2x = 6

x = 6/2

x = 3

Therefore, the value of x = 3 and y = 3
