Answer:
-13n^4 + 11n^3 - 3n^2 - 3
Step-by-step explanation:
*I think you mistyped the question. I belive the 13n^4 is supposed to be negative*
1.First, we need to add common values (all the n^4s together, all the n^3s, etc.) from the two sets.
-13n^4
12n^3 + -n^3
8n^2 + -11n^2
-3
2. Now lets simplify
-13n^4
11n^3
-3n^2
-3
3. Laststly, we put them all into one expression!
-13n^4 + 11n^3 - 3n^2 - 3
Answer:
The approximate total impedance is 7.32ohms
Step-by-step explanation:
The formula for finding the phase angle between the current and source voltage of a simple AC circuit is derived from the relationship:
Cos θ = R/Z
From the formula we can get impedance Z given θ and R
θ is the angle of the total impedance
R is the resistance
Z is the total impedance
Given θ = 35°
R = 6ohms
Z =?
Cos 35° = 6/Z
Z = 6/cos35°
Z = 6/0.819
Z = 7.32ohms
They are supplementary angles. They are located on a straight line, and when added together they will add up to 180 degrees.
