Answer:
The last one
Step-by-step explanation:
If you have a grid with a hundred units and you need to show 1 hundredth (or 1%) you shade in 1 unit. If you need to show a tenth (or 10%) you shade 10 Units. I would need a picture of the grid to help any further.
In the given you wrote -2, whereas it should be -2i
z = a + bi and in trigo form | z |.(cos Ф + i.sin Ф).
z = 0 -2i → | z |.(cos Ф + i.sin Ф)
Now let's calculate z:
z² = a²+b² → z² = 0² (-2.i)² → z = -2(i)² →z= -2(-1) → z = |2|
tan Ф = b/a = -2/0 → tan Ф → - ∞ ↔ Ф = -90° or Ф = 270°
then the - 2 I ↔ |2|(cos 270° + i.sin 270°)
Get x all alone on its own side:
x=16+5
x=21
