Answer:
C) 5.6
Step-by-step explanation:
In an AC circuit, the current changes periodically direction, following a sine-like function.
As a result, we have the following:
- The current through the resistive branch of the circuit is always in phase with the voltage
- However, the voltage in the inductive branch of the circuit preceeds the current by a phase difference of 90 degrees
The inductance of the circuit therefore is basically the resultant vector of the resistance (R) and the inductance (L), and the phase angle is related to the two quantities by the relationship:

In this problem, we have:
is the phase angle
is the resistance of the circuit
Therefore, the inductance is:

Answer: x=5
Explanation: subtract 4 on both sides than divide 2 on both sides and tada
80 degrees is the answer pls mark brainliest
1.B - - original function is y = sqrt(x). If we make sqrt(x+4), we will move the original function to the left 4. If we make sqrt(x+4)+3, additionally the original function will be moved up 3.
2.D - original function is y = sqrt(x). If we make sqrt(x-7), we will move the original function to the right 7. If we make 5*sqrt(x-7), additionally the original function will be expanded throw the y-axis.
3.E - original function is y = x^5. If we make -x^5 (multiply x^2 by -1), we will reflect the original function over the x-axis. If we make -x^5 - 4 , we additionally will move the original function down 4.
4.C - original function is y = x^2. If we make (x-3)^2, we will move the original function to the right 3. If we make x^2 - 5 , we will move the original function down 5.
5.A - original function is y = x^2. If we multiply x^2 by 1/3, function will be compressed about the y-axis.
