The numbers that are irrational are ∛4 and 4 + √5

<h3>How to determine which of the numbers are irrational?</h3>

The numbers are given as:

negative four and 8237 ten thousandths, one half pi, cube root of four, and four plus the square root of twenty-five

Rewrite properly as:

-4.8237, π/2, ∛4 and 4 + √5

When the above numbers are evaluated, we have:

-4.8237 = -4.8237

π/2 = 11/7

∛4 = 1.5874.....

4 + √5 = 6.23606.....

Irrational numbers are numbers that cannot be represented as a fraction of two integers and they are always non-terminating decimals

∛4 and 4 + √5 are non-terminating decimals

Hence, the numbers that are irrational are ∛4 and 4 + √5

Inga [223]

Answer:

The lower the volume, the higher the pressure.

Step-by-step explanation:

Volume and pressure are inverse to each other -- so the more pressure, the less volume, and vice versa. Think of it like this: if you were squished into a tiny room, there would be a lot of pressure on you, and not a lot of volume to move in!

You can also think of it numerically. The higher the V in that equation (the higher the denominator) the lower the p in the equation.

Answer:

Circunferencie can be writen also as a fuction of the diameter of the circle

C = pi*D

Where

D = circunferene diameter

Step-by-step explanation:

C = 2.pi.R = 2.R.pi

In a circle 2.R = D

So,

C = pi.D

Simplify the expression (2x − 9)(x + 6)

kenny6666 [7]

<u>Answer: </u>

Simplified form of given expression (2x – 9 )( x + 6 ) is $2 \mathrm{x}^{2}+3 \mathrm{x}-54$

<u> Solution: </u>

We need to simplify following expression.

(2x – 9) ( x + 6)

For sake of simplicity lets first assume 2x – 9 = A

So expression becomes A(x+6)

= Ax + A6

Now replace A by 2x – 9

= (2x – 9 ) x + (2x – 9 ) 6

$=2 \mathrm{x}^{2}-9 \mathrm{x}+12 \mathrm{x}-54$

On simplification, we get

$=2 \mathrm{x}^{2}+3 \mathrm{x}-54$

Hence simplified form of given expression (2x – 9 )( x + 6 ) is $= 2 \mathrm{x}^{2}+3 \mathrm{x}-54$
