In the series expansion of (1+ax)(4-x)^-1/2 the coefficient of x^3 is -67/2048. Find the constant a?
You worked out coefficient of x^3 is 5/2048 which is correct.
so, (1+ax)(4-x)^-1/2 = (1+ax)(1/2 + 1/16x + 3/256x^2 + 5/2048x^3 + ... )
hence, ax * 3/256x^2 + 1 * 5/2048x^3 = -67/2048x^3
x^3( 3/256a + 5/2048) = -67/2048 x^3
a = -3
The sum of a geometric series is -2048. If the first term is -4 and the common ratio is 2, what is the final?
tn = ar^(n-1)
Sn = a(1 - r^n)/(1 - r)
-2048 = -4(1 - 2^n) / (1 - 2)
-2048 = 4 - 4*2^(n)
-2052 = -4*2^n
513 = 2^n
log(513) = log(2^n)
log(513) = n*log(2)
n = 9.0028
tn = a*r^(n-1)
tn = 4*r^(8.0028)
tn = 4*2^8.0028
tn = 1025.98
Which makes absolutely no sense whatever. This sum implies that either the steps are not integral which they usually are, or that the sum is incorrect or that a or r or both are not right.
I've always interpreted "this generation" as a trans-chronological meaning - that "this generation" means "whoever is reading this". Then He says "until all these things take place". He gave us several warnings in different parts of the Bible that tell us the things that will be happening simultaneously just before He returns:
1) Wars and rumors of wars
2) Earthquakes, Floods, storms (Several hundred years ago, major earthquakes only happened once every few hundred years - now they happen every day worldwide)
3) Pestilences (Cancer, AIDS, etc.)
4) Famines (Africa and 3rd world countries)
5) Knowledge will increase (in 100 years, we've gone from horse-and-buggy technology to cars, computers, space shuttles and cloning)
6) An explosive interest in the Occult (Harry Potter, "American Haunting", Buffy the Vampire Slayer, Lord of the Rings, "New Age", John Edwards, etc.)
7) People's love will grow cold
8) People will run to and fro (highways, airports)
9) Increased interest in Bible prophecy
10)Gospel will go out to the whole world (satellite and radio have allowed the Gospel to reach formerly remote and unreachable places)
11) Signifcant increase in crime and immorality
12) Satan will attempt to establish a one-world government and one-world religion (United Nations)
I do believe, that at the pace things are going in our world, that Christ will return before 2048, in my lifetime.
It is only 2Gb (or GB, or gb or gB or whichever way round it is). Go buy from a different company, as this one obviously has no problems with lying to you and assuming you are stupid so they can get your money off you.
On the other hand, 2Gb is fine for most computing purposes.
Error -2048: The File Is Not A Movie File.
This error message means that QuickTime cannot play a particular file. However, it doesn’t necessarily mean that the file really doesn’t contain video that you could play back with some other software, because the error happens even with legitimate WMV (Windows Media Video) movie files.
Find and use a media player that supports the type of video file you want to play, such as Windows Media Player for WMV files. If no media player can open the file, the video may be corrupted or was created with special settings that affected its compatibility.
i cant believe im the only person in the world that has this problem,i cant get any attachments on my e mail..?
Errorr 2048 means the playlist and code doesn't match, usually in quicktime.
The reason you have this error is because of Quicktime 7.6.
The QuickTime MPEG-2 Playback Component has been updated for compatibility with QuickTime 7.6. If you are a past purchaser of the QuickTime MPEG-2 Playback Component, then you can download the new software by visiting the Apple Online Store and clicking on "Account" in the Store menu. Click "Downloadable Software Purchases," enter your Apple ID and password, and you will see a link to the QuickTime MPEG-2 Playback Component. Click the link to download and install the new version.
or the complicated way...but free...
Rename all your files that quicktime can’t read, to .wmv all occurances of the -2048 error come from codec misuse by the mis-naming of the 'quicktime' files.
Then download any transcodal translator. I used VLC Player, which can do pretty much anything.
VLC Site: — > http://www.videolan.org/
Once downloaded you’ll find it can play your 'broken files'.
Proceed to click on File — >Streaming/Exporting WIzard...
Go through: 'Transcode/Save to file'
Then: Select either select streaming file from location:
Select File from existing playlist. (Open(ed) files)
Last: Select how you want it TRUELY encoded as anything from mpeg4 video and audio to DivX to H. 264 to Theora REMEMBER: select the transcode buttons.
(Don’t forget bitrate has an extreme importance the more bits the higher quality but it comes at a price as the video becomes larger. It won’t be 100% quality, maybe 95% max; usually around 85 - 90% normal quality.)
Next: select your encapsulation method you want this to match your codec so please match them, it causes less problems.
Almost Done: Select a save location and wammo your done!
Finally: Click FINISH and it shows you all your work one last time before you complete the transcode.
Ta-Da Quicktime Video Problem Error -2048 SOLVED!
2^(x-12) = 2048
First rewrite 2048 as an exponent with a base of 2.
2^(x-12) = 2^11
Now set the powers equal to each other and ignore the 2's.
x-12 = 11
Now solve for x by adding 12 to both sides.
x = 23
where can i get a picture 2048 pixels wide and 1152?
The standard specification is 2048 x 1136 pixels. If it is essential that you must have a 2048 x 1152 pixel image then you can try to open any image in GIMP and convert it into a 2048 x 1152 pixel image. Using a 2048 x 1136 image as the original will give you best results.
It's happening to me as well. I figured I would catch up on some Big Bang Theory, but I've been running into 303: Error #2048 quite a few times already. As dude said before, we're pretty much just gonna have to wait for the servers reset or whatever the hell it is they do. In the mean time you can attempt trying to stream via the other links present. On Season 4 episode 2 I ran into the same error until the third link I believe, which actually worked. Admittedly the system has seemed a bit sluggish today, though.
EDIT: Not even a minute after I typed this I clicked on one of the bugged-out links and it worked no problem.
Ga is Georgia
L is a legislative act
1990 is the year of act
p 2048 is the page of the cite
5 is the section for the cite specifically.
This was used as a researchers footnote and the actual authenticity of the laws cited in the case books?
whats a better resolution 2048 x 1152 or 1920 x 1200?
2048 x 1152 = 2359296
1920 x 1200 = 2304000
so the first has a few MORE pixels...
They are different ASPECT ratios:
2048 x 1152 is a 9 x 16 ratio (standard HDTV or WS)
Regular screens (TV) are 3 x 4 aspect ratio
1920 x 1200 is a 5 x 8 ratio
Both are vary close, so choose the one that matches the aspect ratio of the screen you have!
You are SCREWED.
Even if you used 100 of the most powerful computers in the world you wouldn't be able to get any sense out of that file until the end of the universe. 2048 bit is overkill for that strength encryption.

"Possible" is one of those open-ended words that can have all sorts of meanings.
I sometimes like to mess with our customers, coz they'll ask, "Is it possible to add this function," and I'll say, "Yah, it's POSSIBLE -- but it's gonna COST you!"
THEY meant, would I do it for FREE. Well, I try to disabuse them of that notion as quickly as I can.
Same thing here -- is it POSSIBLE?
YES, IT IS -- how many dudes, decades and dollars do you want to allocate to the job?
Especially 2048 bit, that's getting into NSA territory. That's getting into encryption strength where it would be quicker to just capture you and torture you until you give us the password. (Ve have vays of making you talk.)
So, I say, you wanna mess with your friend, sure go right ahead. Or if you REALLY want to mess with him, use a different encryption package FIRST -- E.g., use PGP to encrypt a file, then take the result, and encrypt it again with Diamond2. But DON'T TELL HIM that!
I guarantee you he'll never crack it in his lifetime.

2048= 2×2×2×2×2×2×2×2×2×2×2= 2×2¹⁰
[486/2048]^ -4/5 *5
