Answer:
The complex number in the form of a + b i is 3/2 + i √3/2
Step-by-step explanation:
* Lets revise the complex number in Cartesian form and polar form
- The complex number in the Cartesian form is a + bi
-The complex number in the polar form is r(cosФ + i sinФ)
* Lets revise how we can find one from the other
- r² = a² + b²
- tanФ = b/a
* Now lets solve the problem
∵ z = 3(cos 60° + i sin 60°)
∴ r = 3 and Ф = 60°
∵ cos 60° = 1/2
∵ sin 60 = √3/2
- Substitute these values in z
∴ z = 3(1/2 + i √3/2) ⇒ open the bracket
∴ z = 3/2 + i √3/2
* The complex number in the form of a + b i is 3/2 + i √3/2
Answer:
504
Step-by-step explanation:
We are solving for the left leaning poll
Total voters = 900 + 1100
= 2000
Number of voters who say trump was responsible = 56percent x 2000
= 1120
Number of those who say otherwise = 44% x 2000
= 880
For this network
Those who say trump is responsible = 1120 x900/2000
= 1008000/2000
= 504 registered voters
