What is Spin?

Spin is a conserved quantity carried by elementary particles, and thus by composite particles and atomic nuclei.

Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum.

the answer is 319. (638/2=319) square means doubled so you want to find what was double to get the above. So you then would divide by 2 and get your answer.

Which polynomial has (3x + 2) as a binomial factor? 6x3 + 3x2 + 4x + 2 12x2 + 15x + 8x + 10 18x3 – 12x2 + 9x – 6 21x4 + 7x3 + 6x + 2

Answers

If binomial (3x+2) is a factor of some polynomial, then number $x=-(2)/(3)$ is this polynomial's root. Check all polynomials:

A. For the polynomial $6x^3 + 3x^2 + 4x + 2,$

$6\left(-(2)/(3)\right)^3 + 3\left(-(2)/(3)\right)^2 + 4\left(-(2)/(3)\right) + 2=-(16)/(9)+(4)/(3)-(8)/(3)+2=-(10)/(9)\neq 0.$

B. For the polynomial $12x^2 + 15x + 8x + 10,$

$12\left(-(2)/(3)\right)^2 + 23\left(-(2)/(3)\right) + 10=(16)/(3)-(46)/(3)+10=0.$

C. For the polynomial $18x^3-12x^2 + 9x-6,$

$18\left(-(2)/(3)\right)^3 -12\left(-(2)/(3)\right)^2 + 9\left(-(2)/(3)\right) -6=-(16)/(3)-(16)/(3)-6-6\neq 0.$

D. For the polynomial $21x^4 + 7x^3 + 6x + 2,$

$21\left(-(2)/(3)\right)^4 +7\left(-(2)/(3)\right)^3 +6\left(-(2)/(3)\right) +2=(112)/(27)-(56)/(27)-4+2\neq 0.$

Can someone help? 12x−2y=8 not in a faction and not is a decimal.

Answers

Add 2y to both sides

12x-2y+2y= 8+2y

12x = 2y+8

Divide both sides by 12

12x/12 = (2y+8)/12

x= 1/6 y + 2/3
