We have a 1 by 3 matrix multi[lied by a 3 by 5 matrix so the answer will be a 1 by 5 matrix 1 row 5 columns
Multiplying matrices is always row by colums
column 1: 14*1.2+16*0+18*1.4=16.8+25.2=42
column two:14*0+16*1.6+18*1.8=25.6+32.4=58
column 3:14*1.4+16*1.6+18*0=19.6+25.6+0=45.2
column 4:14*2.6+16*2.8+18*3=36.4+44.8+54=135.2
column5: 14*5.2+16*4.7+18*4.4=16.8+25.2=72.8+75.2+79.2=227.2
(42,58,45.2,135.2,227.2)
