WolframAlpha evaluates it as  :

399313452966 / 1975

BTW.....welcome to the site......!!!!!

The result is indeed e/(2lambda):

Guest is correct, see more detail below:

صديقي العزيز، يرجى الكتابة باللغة الفارسية والإنجليزية

Dear friend, please write in Farsi and English

Yes, this is afunctional site

It would be like marrying a lady without firstly asking her father for her hand.  Only a man of low morals would do such a thing and Sir CPhill is not such a man.

---------

Sir CPhill did you ask your wife’s father for her hand in marriage?

Amber told me when I ask her dad for her hand in marriage he will tell me I have to take the rest of her too . hahaha

I not ask him that for a long time because we are way too young to get married, but I did ask him for permission to court his daughter. That is one of my journal stories.

Why don't you post them on here DS? 

You know even I'm a sketcher. I mean I have become one. I've been practicing and practicing and finally I've created a beautiful sketch or drawing of an anime boy! Yes you guessed it, I was too fascinated by those beautiful anime faces that I thought to draw some myself! And yep I succeeded! Everybody was very amazed! I'll try and post some of my drawings here.

you got a competitor bro!!!!LOL!

i just love sketching!!!

I wanted to come back to this one and solve it with substitutions......

(1) b=d+f   →  f = b - d  

(2) e=c+f   →  f = e - c

(3) 12=10c+20e   →   6 = 5c + 10e

(4) 0=10f+20b-10c  →  0 = f + 2b - c

 (5) 0=10d-20e-10f  →   0 = d - 2e - f

Subtract (2) from (1)

b - e  = d - c   (6)

Add  (4) and (5)

0 = 2b - 2e + d - c   →   d - c  = 2e - 2b

Substitute  the previous result into (6) for d - c

b - e = 2e - 2b  →  3b = 3e   →   b = e    and from(6) this implies that  →   d = c

Substitute (2)  and  the fact that b = e   into the rearrangement of (4)

0 = e - c + 2e - c → 2c = 3e  → e = [2/3]c

Substitute the previous result into the rearrangement of   (3)

6 = 5c + 10(2/3)c  →  18 = 15c + 20c  →  18 = 35c  →  c = 18/35  →  d = 18/35

And   e = [2/3]c  = [2/3](18/35)  = 12/35  =  b

And f = b - d    .....so   f =  12/35 - 18/35  = -6/35

Alan's answers are correct......I may have mis-typed something when I put the system into WolframAlpha.....!!!!

[When I put this system back into WolframAlpha, it still says no solutions exist.....odd!! ]

You can enter it just like this in the on-site calculator :

0.9807^10

It will give you the result   0.8229......

Then, BS-Scout it is for you, Dragonlance !!!!........we merely have to await final approval from Her Majesty.......

If the cows are on the hill I can bring you muck boots so you not slip as much when you push the bolder. :)

You know I pretty sure it was Naus who trick you into looking for the roman zero. It seem like his writing.

http://web2.0calc.com/questions/how-many-current-digits-of-pi-are-known

Wow look at all the points Naus  get on his birthday post to you.  I guess a lot of people think it’s funny. I get a lot on my story posts but not that many.  

Hahaha I would be a great BS scout. If there is one thing I know it is BS. I shovel tons of it. I can tell if it is from a heifer, cow, steer, or a intact bull.  I pretty good at sniffing out the people kind too because there is way more of that around.  hahaha

Example:    4^(-3)  =   1/4^3   

On the Web2.0 calculator    enter   '4'   then  y^x   then 3  then +- key then =

OK......thanks, guest.....I stand corrected......!!!!

CPhill: Just plugged it into WolframAlpha and it also gives infinity????!!!!!!!!.

How many days has it been since feburary 14th 2005

From Feb. 14, 2005 to today Dec. 26, 2015=3,967 days

You can calculate the elapsed days here.........http://www.timeanddate.com/date/durationresult.html

Look att he graph of the function, here.......https://www.desmos.com/calculator/m8gxiqxa9c

Would it be more accurate to say that the limit does not exist.......since the function "ping-pongs"  between values defined by two non-parallel lines as x approaches infinity    ???

Anyone else have any thoughts about this question ????

thanks CPhill ! :)

Notice that a tangent line drawn from the center of the circle to the point of tangency will meet the given line at right angles..........thus, these two lines will have reciprocal slopes....

And the equation of the line through the origin will be

y = x

So......setting these two equations equal, we have

x = -x + 4      add x to both sides

2x = 4

x = 2

So, at the point of tangency, y = x, so  y = 2

And the radius of such a circle centered at the origin will be

sqrt (2^2 + 2^2) = sqrt (8)

So....the area of this circle will be

A = pi [sqrt(8)]^2   =  8pi     and dividing this by pi   will produce a result of 8

Here's a graph of the situation ......https://www.desmos.com/calculator/g8eurlqsyo

x^2+x >1/e^4        make this an equality and complete the square

x^2 + x + 1/4 = 1/e^4 + 1/4       factor the left side, simplify the right

(x + 1/2)^2  = [ 4 + e^4] / [4e^4)   take the square root of both sides

x + 1/2  =  +/- sqrt [ 4 + e^4] / [2e^2]

x = +/- sqrt [ 4 + e^4] / [ 2e^2] - 1/2  ≈  [ -1.0179919293664084, 0.0179919293664084 ]

The answer  will come from one or more of these intervals

(-infinity, - sqrt [ 4 + e^4] / [ 2e^2] - 1/2) , (- sqrt [ 4 + e^4] / [ 2e^2] - 1/2,  sqrt [ 4 + e^4] / [ 2e^2] - 1/2), ( sqrt [ 4 + e^4] / [ 2e^2] - 1/2, infinity)

Choosing 0 as a test point for the middle interval will make the inequality false

So.....the two outside intervals solve the inequality

Here's the graph that proves this........https://www.desmos.com/calculator/iluvf1vudp

I am from Azerbaijan in our country it s TQDK but i am gonna to take SAT

lim((x^2+bx)/(x-1)-x+2)=0,x->infinity

b = -3. Unfortunately, my software is not working properly to give you step-by-step solution. Sorry about that. See if you can get the same answer. The answer is ACCURATE.

Simplify the following:
-(5/2+7/3)

Put 5/2+7/3 over the common denominator 6. 5/2+7/3  =  (3×5)/6+(2×7)/6:
-(3×5)/6+(2×7)/6

3×5  =  15:
-(15/6+(2×7)/6)

2×7  =  14:
-(15/6+14/6)

15/6+14/6  =  (15+14)/6:
-(15+14)/6
