Answer:

Using coal, steam, and <u>OXYGEN,</u> the fischer-tropsch procedure converts coal into a liquid fuel.

Step-by-step explanation:

A series of chemical reactions in which hydrogen and carbon monoxide converges into liquid hydrocarbons by using a metal catalyst. This process is called The Fischer-Tropsch process.

Converting Coal into Liquid Fuel is know as Coal liquification.

IN Liquification process Oxygen, heat is used.

Therefore steam is for heat and oxygen to covert coal into liquid fuel.

Prove Euler's identity using Euler's formula.<br> e^ix = cos x + i sin x
Korolek [52]

First list all the terms out.

e^ix = 1 + ix/1! + (ix)^2/2! + (ix)^3/3! ...

Then, we can expand them.

e^ix = 1 + ix/1! + i^2x^2/2! + i^3x^3/3!...

Then, we can use the rules of raising i to a power.

e^ix = 1 + ix - x^2/2! - ix^3/3!...

Then, we can sort all the real and imaginary terms.

e^ix = (1 - x^2/2!...) + i(x - x^3/3!...)

We can simplify this.

e^ix = cos x + i sin x

This is Euler's Formula.

What happens if we put in pi?

x = pi

e^i*pi = cos(pi) + i sin(pi)

cos(pi) = -1

i sin(pi) = 0

e^i*pi = -1 OR e^i*pi + 1 = 0

That is Euler's identity.

How do you simplify this
Dafna11 [192]

Top:

x / (x + 1) - 1 / x

= [x^2 - (x +1)] / x(x+1)

= (x^2 - x - 1 ) / x (x+1)

Bottom:

x / (x + 1) + 1 / x

= [x^2 + (x +1)] / x(x+1)

= (x^2 + x + 1 ) / x (x+1)

Now you have:

(x^2 - x - 1 ) / x (x+1)

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

(x^2 + x + 1 ) / x (x+1)

= (x^2 - x - 1 ) / x (x+1) * x (x+1) / (x^2 + x + 1 )

= (x^2 - x - 1 ) /(x^2 + x + 1 )

Answer:

x^2 - x - 1

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

x^2 + x + 1

Please help with these questions!!:))
Sonbull [250]

Answer:

The first one : decay

The second one : growth

When the argument of the exponential expression is bigger that 1 then it represents a growth

When it's less than 1 and above 0 then it's a decay
