Answer:
1125.4 Hz
Step-by-step explanation:
The resonant frequency is the frequency at with the inductive reactance is equal to the capacitive reactance. It is given by the relation ...

where L is in henries, and C is in farads.
__
For the given circuit values, the resonant frequency is ...

The resonant frequency of this circuit is about 1125.4 hertz.
The image doesn't make sense. The triangle is isosceles but yet 13=18. Could you help me verify which sides 13 and 18 are?
Given number is 4,8100,000,000,000.
In this number of zero is 11. So we can write it as

But for scientific notation we will enter decimal after two place in reverse direction.For this we will also multiply number by 10^2.
So number will be

So fourth option is correct.
Answer:
Always
Step-by-step explanation:
Some people might mistaken it for sometimes, but the part that makes it always is when it says "regular" hexagons.
Similarity is defined by having congruent angles and proportional sides. Regular hexagons will always have internal angles of 60°, meaning that any two regular hexagons will always be similar.
Your answer will be 130 i think ,, pretty sure though
