PLS HELP ASAP WILL GIVE BRAINLIST what is true about the complex number -5+5i, check all that apply
a. it lies in quadrant 2
b. it lies in quadrant 4
c. the modulus is 5√2
d. the modulus is 10

it lies in quadrant 2

Step-by-step explanation:

in a graph there are 4 quadrant .out of them your question match with second quadrant because the in that sign must be negative and positive

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
