D) 12 would NOT be a possible length for the third side because the sum of the 2 shorter legs should be greater than the longest leg.
You are right. Transitivity means, that:
if a = b and b = c, then a = c
(here a = x, b=5 and c = y).
Answer:
<em>The voltage at the middle source is</em> 
Step-by-step explanation:
<u>Voltage Sources in Series</u>
When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.
The figure shown has three voltage sources of values:



The sum of these voltages is:

Operating:

We know the total voltage is
, thus:

Equating the real parts and the imaginary parts independently:
4+a=6
1+b=-3
Solving each equation:
a = 2
b = -4
The voltage at the middle source is 
Answer:
A. Cos2x
Step-by-step explanation:
f(x) = sin(x)cos(x) = (1/2) sin(2x) using double angle formula.
f'(x) = ( (1/2)sin(2x) )' = 2(1/2)cos(2x) = cos(2x)
