Difference between bar code and qr code?
Bar code stores numbers only,but QR code can be store be with any multimedia.
Point b is between q and r on qr and qb equals 20 br equals 10?
This isn't a question, even. It's a statement about a line segment, QR.
Why is the difference between two rational numbers always a rational number?
Suppose x and y are two rational numbers. Therefore x = p/q and y = r/s where p, q, r and s are integers and q and s are not zero.Then x - y = p/q - r/s = ps/qs - qr/qs = (ps - qr)/qsBy the closure of the set of integers under multiplication, ps, qr and qs are all integers,by the closure of the set of integers under subtraction, (ps - qr) is an integer,and by the multiplicative properties of 0, qs is non zero.Therefore (ps - qr)/qs satisfies the requirements of a rational number.
Who invented QR code?
The Quick Response (or QR) Code was invented by the Denso Wave company to track the vehicle manufacturing process.
Why is the multiplication of rational numbers always result in a rational number?
It follows from the closure of integers under addition and multiplication.Any rational number can be expressed as a ratio of two integers, where the second is not zero. So two rational numbers may be expressed as p/q and r/s.A common multiple of their denominators is qs. So the numbers could also have been expressed as ps/qs and qr/qs.Both these have the same denominator so their sum is (ps + qr)/qs.Now, because the set of integers is closed under multiplication, ps, qr and qs are integers and because the set of integers is closed under addition, ps + qr is an integer.Thus the sum has been expressed as a ratio of two integers, ps + qr, and qs and so it is a rational number.

What is the meaning of QR?
A QR code (QR = Quick Response) is a two-dimensional barcode.
What is the meaning of QR in physical science?
A QR code (QR = Quick Response) is a two-dimensional barcode.
Meaning of QR in airlines operations?
QR is the flight code for Qatar Airways, which is put before every flight number that they operate or have a code-share on. For example QR101.
What is the regular configuration of QR bar codes?
The regular configuration of a QR barcode is 3 squares in the corners of the code and pixelated squares in between them. One could also make custom QR barcodes.
How do you factor 4qr - qr cubed?
To factor the expression 4qr - qr^3, we first notice that both terms have a common factor of qr. We can factor out qr to get qr(4 - r^2). Next, we recognize that 4 - r^2 is a difference of squares, which can be factored further as (2 + r)(2 - r). Therefore, the fully factored form of 4qr - qr^3 is qr(2 + r)(2 - r).
