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>
D. what is the maximum mass of a railcar that can hit the spring without breaking 2 m/s
Answer:
d = 30
Step-by-step explanation:
d = 28 + 16 -14
d = 44 - 14
d = 30
I guess it helps u dear
In y = mx + b form, the slope will be in the m position
y = mx + b
y = -7x + 9
notice that in the m position, the number is -7. That means ur slope = -7
