Using Descartes' Rule of Signs:
The signs are: - + - + - +
There are 5 signs changes in this sequence, so there could be either 5, 3, or 1 positive roots.
If we negate the terms with odd numbers (x^5, x^3), we end up with the signs: - - - - - +
Since there is 1 sign change, there can be only 1 negative root.
This means the positive and negative roots can either be 6, 4, or 2.
Since the total number of roots cannot exceed 6, there are either 0, 2, or 4 complex roots.
It is 3.0625 becuase to combine them in any way they have to have the same denominator.
Answer:
2.0
Step-by-step explanation:
Area of Shaded Region = Area of square – Area of circle
Area of square = 3×3 = 9
Area of circle = π×r² = π×1.5² ≈ 7.068
(radius of circle is half of the side length)
9–7.068≈2.0
