Answer:
Arc ECG is the major arc
Step-by-step explanation:
Arc ECG is made by an angle which is greater than 180°.
All the other arcs listed are made by angles which are 180° or less than.
The greater the angle measure the greater the arc length.
Answer:
D
Step-by-step explanation:
The sqrt of (34 m^4) is sqrt(34) times sqrt(m^4).
The sqrt of m^4 is easy ... that's just m^2 .
The other part is more messy. There's not much you can do with it.
sqrt(34) = sqrt(17) times sqrt(2).
That doesn't help make it any simpler.
You might as well just leave it as sqrt(34).
Then the final, simplified form of the original expression is
m^2 sqrt(34)
All you do is divide.
330/390= 0.846
round it: 0.85
Answer is about 85%
