Note: this is a multi-part . once an answer is submitted, you will be unable to return to this part determine whether the relation on the set of all people is reflexive, symmetric, antisymmetric, and/or transitive, where (a. b) e rif and only if ind b have a common grandparent. (check all that apply) reflexive symmetric transitive antisymmetric

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the answer is 31.27mph

1; 35 is the ratio
