Answer:
Step-by-step explanation:
The finite set is  in which we can count the elements which has finite number of elements
option 1 is not correct because we can not count the whole numbers they could extended upto infinite.
Option 2 is correct that is finite because condition is given that is natural numbers less than 100,000.
Option 3 is finite because we can count all letters of the alphabet.
Option 4 is not finite because all odd numbers can be extended upto infinity.
Option 5 is correct that is finite because world's population will be a finite number.
Option 6 is finite because it is empty set which is finite.
 
        
                    
             
        
        
        
Answer:
-8i
Step-by-step explanation:
To multiply numbers is polar form
z1 = r1 ( cos theta 1 + i sin theta 1)
z2 = r2 ( cos theta 2 + i sin theta 2)
z1*z2 = r1*r2 (cos (theta1+theta2) + i sin (theta1+theta2)
z1 = 2(cos 70° + i sin 70°) 
 z2 = 4(cos 200+ i sin 200)
z1z2 = 2*4 (cos (70+200) + i sin (70+200)
z1z2 = 8 (cos(270) + i sin (270))
        = 8 (0 + i (-1))
        =-8i

75% = 75/100÷ 5= 15/20 ÷5= ¾. does this help? hope it does
hope it helps :)
