Well first you want to define the parts of the triangle. The second thing to do is learn to make a unit circle. The third thing to do is know the functions. The last thing to do is find the relationships.

Learn SOH-CAH-TOA (In right triangle)
SOH = sinQ = opposite/hypotenuse
CAH = cosQ = adjacent/ hypotenuse
TOA = tanQ = opposite/ adjacent

Simplify the expression (-3x)^4

Sati [7]

(-3x)⁴

Basically, just do this :

(-3x) × (-3x) × (-3x) × (-3x)

So now you have 9x² × 9x²

9 × 9 = 81

x² × x² = x⁴

So, your answer is 81x⁴

~Hope I helped!~

In a parallel circuit, ET = 240 V, R = 47 kΩ, and XL = 50 kΩ. What is the reactive power?

Fittoniya [83]

Answer:

Reactive power is 1.152 VARs

Step-by-step explanation:

We are given that in a parallel circuit, $E_{T}=240V$ ,R=47kΩ and $X_{L}$ =50kΩ.

reactive power means the dissipating power resulting from inductive and capacitive loads measured in volt-amperes reactive(VAR).Since our circuit has inductor only, reactive power will be power dissipated from inductor.

Current through inductor= $\frac{E_{T}}{X_{L}} =\frac{240}{50}=4.8$ milli amps=0.0048 A

Reactive power = (current flowing through inductor)X (Voltage across inductor)

Hence reactive power = 0.0048 X 240=1.152 VARs
