Question

1)Find the modulus of the complex number √5+3i.
2)solve -12x > 30,when x is a natural number.
3)find the slope of the line 8x-4y+1=0
4)if AXB= {(1,x),(2,x),(3,x),(1,y),(2,y),(3,y)},find BXA.
5)Find the principal solutions of the equation tanx=√3find the slope of the line x by 3 + 5 by 2 is equal to 1

Answer 1

modulus = √(√5)^2+3^2=√5+9=√14

Answer 2
