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
Answer:
<h2>68 is the fourth number.</h2>
Step-by-step explanation:
The average of the 4 numbers is 45.
Hence, the total of the four numbers is
= 180.
The given three numbers are 24, 36, 52.
The total of the given three numbers is (24 + 36 + 52) = 112.
The fourth number will be (180 - 112) = 68.
