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:
Independent variable: C
Dependent Variable: M
Step-by-step explanation:
Lets begin with the Independent variable, C. C is moreover a result, so it remains as a dormant number that is yet to be known. M which is the dependent variable, contributes to the corresponding number we call the cost. When M , a quantity that is being manipulated the number 0.6, multiplies "per mile" plus 25. The actual expression is 25 + 0.6m, and the indpendent variable is known as the numerical coefficient.

how would i know the answer
Step-by-step explanation:
The correct answer is <span>C. Diagonals bisect each other
That is not a property of a kite because its diagonals intersect at right angles. Diagonals that bisect each other appear on things such as rectangles. </span>
