Books are identified by an international standard book number (isbn), a 10-digit code x1x2â¦x10, assigned by the publisher.
these 10 digits consist of blocks identifying the language, the publisher, the number assigned to the book by its publishing company, and finally, a 1-digit check digit that is either a digit or the letter x (used to represent 10).
this check digit is selected so that â10i=1ixiâ¡0 mod 11 and is used to detect errors in individual digits and transposition of digits.

(a) the isbn for a book is 8â51â532734âq where q is the check digit. what is q?

(b) the isbn of another book is 5â707â15m25â8. find the digit m.

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

no this is a nonlinear negative

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
