Answer:
the angles are called vertical angles and they are equal.
Use the Law of Sines or the Law of Cosines with non-right triangles.
Step-by-step explanation:
We have to find f ( i ) for the function: f ( x ) = x³ - 2 x²
f ( i ) = i³ - 2 i²
We know that: i² = - 1 and i³ = - i
f ( i ) = - i - 2 · ( - 1 )
f ( i ) = - i + 2
The complex number is written in form: z = a + b i
Answer:
f ( i ) = 2 - i
I believe the answer is 19 cm, because you compare 8cm to the other side, it's basically the same. Multiply 2 x 8 and you get 19 cm.
There are an infinite amount of solutions to the system because the equations represent parallel lines. Whenever you get a true statement like 0 = 0, you know that there are infinitely many solutions. This is because the equations represent lines that never intersect, which are parallel lines. Remember that ALL lines go on forever, they never end.
