Which of the following sets of data would you likely represent with a square matrix? check all that apply. a travel company wants to use a matrix to represent the number of flights of several different airlines to several different cities. a tennis club has a tournament in which each member plays every other member, and represents the scores in a matrix. a coefficient matrix is used to represent a linear system with 3 equations and 3 unknowns. the augmented matrix is used to represent a linear system with 3 equations and 3 unknowns.

Answer : B and C

Explanation :

firstly, we should know the definition of square matrix. It is a matrix in which number of rows is equal to number of columns

In case of A : it is given that several number of airlines  and several number of columns

if we consider the case of more number of airlines say 5 and we have only 4 cities that these 5 airlines offer services to. Then it will not  form a square matrix

NOTE: it would have formed the square matrix if there would have been equal number of airlines and  cities.

In case of  B: in this case we will have equal number of members in each team.

In case of C : in this case we are given with equal number of  equations and unknowns

In case of D: in this case we have augmented matrix which is formed by appending the column of the matrices given so it can never form a square matrix.

B and C

Step-by-step explanation:

These are the correct answers on ed-genuity, hope this helps! :)

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
