Answer:
Step-by-step explanation:
radius r=C/2π
r=47/2π
r=47/ 6.2831853071796
r=7.48028233
<span>the correct equation is
- 4j² + 3j - 28 =0
ax² + bx + c,
a = -4, b=3 c =- 28.
The discriminent D = b² - 4.a.cD = 3² - 4(-4)(-28)D = -439
If D ≥ 0 there are either 2 roots or one double if = 0)if D< 0, there are no real roots (but 2 imaginary roots)Since D < 0, then there is no real roots
The answer there is no real roots</span>

Angles of rotation that would not map the shape on itself
Side of a nonagon is:
and a complete rotation is:
To start with, we calculate a possible angle of each rotation:
This is calculated by dividing the complete rotation by number of sides
The question lacks option; so, it's difficult to give a specific answer.
However, I'll give a generalized answer
For the nonagon to map on itself, the angle must be a multiple of the calculated angle of rotation (40)
i.e.
<em>Any angle different from the above listed angles (or any other multiple of 40 not listed above) answers the question.</em>
