You describe the resultant computed using the graphical method by connecting the vectors head to tail. The difference from the tail of the first one to the head of the last one is the resultant vector. To determine resultant vector with the component method you use the formula x(squared) + y(squared) = R (squared).
When the power (energy) is dropped to the value of 50 percent, the decibel loss is 3 dB, but the voltage is dropped to the value of 70.1 percent. Power drop to 50 % means -3 dB; that is 70.1 % voltage drop. Power drop to 25 % means -6 dB; that is 50 % voltage drop.

3 squared is 3 x 3 or 9.
Nine
-3
If you mean: (x+3) squared = (x+2) squared +11 Then the value of x works out as 3
The vertex of this parabola is at -2 -3 When the y-value is -2 the x-value is -5. The coefficient of the squared term in the parabola's equation is -3.
x = 3/sqrt(2) or 1.5*sqrt(2)
The vertex of this parabola is at -3 -1 When the y-value is 0 the x-value is 4. The coefficient of the squared term in the parabolas equation is 7
-3
-5
-3
Seems to us that any value at all can be squared.
She isn't. 4x squared is 4 times (x squared). That is, 4 times (3 squared) = 4 times 9. If you want it to be the square of 4x (which would be the square of 4 times 3, ie, 12), you have to write it as (4x)squared.
