Question:Each binary digit is termed a bit. A series of 8 bits is grouped together into a word, which is called a byte. A byte can represent 28 = 256 different combinations, which is sufficient to record a typical 8-letter word in a sentence. A typical 400 page book has about 2 x 105 words. Estimate the number of books that can be stored on a 1.35 gigabyte computer.

Answers:28 does not = 256. 2^8 does. But storing 8 letters in one byte is not resonable unless you are using a compression scheme. Typically, uncompressed text is one byte per letter or character, in ASCII. A two letter word, not counting capitals, could be one of 26 times 26 possible combinations, which is much more than 16 times 16 = 256. 2 x 105 = 210, which is only half a word per page. 2^105 is more likely. Also, 1 gigabyte can be 1 times 10^9 = (1000) ^3 bytes if you talk to a hard drive manufacturer, or it can be 2^30 = ( 1024 ) ^ 3 as Windows displays it. regardless, divide 1.35 x 10^9 bytes by 2^105 words per book, to get the number of "byte books per word." Then divide by the number of "bytes per word" to get the number of books.

Question:Solve the following 2 problems: 1. Solve for x: (3)(sqrt2x) -10 = 0 << I got x =8 >> 2. Solve for the negative value of x: (x - 3) ( x - 2) = (x + 5) (2x - 3) + 21 << Is it -1/500 (-0.002) ?? >> Find the product of your answers. Raise this product to the power of the absolute value of the sum of your answers. << I don't understand this part at all!! >> I need that final answer mostly! If you can explain how you got it great, but if not just the answer is fine so that I can use it to get to the last Box #9! Here is the website to the actual problem, it is easier for you to understand there: http://mathbits.com/Caching/A16807.html I've been working on this for many hours so any help is much appreciated!!!!!!!

Answers:Solve the following 2 problems: 1. Solve for x: (3)(sqrt2x) -10 = 0 << I got x =8 >> This is correct. 2. Solve for the negative value of x: (x - 3) ( x - 2) = (x + 5) (2x - 3) + 21 << Is it -1/500 (-0.002) ?? >> This is however wrong. The answer should be x = 0 or -12 when you solve the quadratic equation. Since the negative value is required, x=-12. For this part... Find the product of your answers. Raise this product to the power of the absolute value of the sum of your answers. To find the product, take 8 mutiply by -12 and you get -96. The absolute value of the sum of your answers is calculated you take -12 + 8 which gives -4 and taking absolute will give 4. So taking -96 to the power of 4 gives you 84934656. I tried it and it works! =) I hope it helped. Good luck!
