Find an invertible matrix P and a matrix C of the form(a -b b a) such that the matrix A = (2 -37 1 4) has the form A = PCP^-1. The eigenvalues of A are 3 + 6 and 3 - 6 with corresponding eigenvectors (6 + i i) and (6 - i i). A The matrices P and C are.
B. There is no matrix C of the form [a -b b a] and no invertible matrix P such that A = PCP^-1

idk

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

i dont know

brandon has 4344 video games.  

step-by-step explanation

7373 - 2929 = 4344

pls let me know if it was correct
