Suppose that y is directly proportional to x and that y = 10 when x = 3. Complete parts (a) and (b). (a) Find the constant of pr
Yuliya22 [10]

For this case we have that if "y" varies directly with "x", then it is true that:

y = kx

Where:

k: It is the constant of proportionality

We have according to the data that:

10 = k (3)

We find the value of "k":

k = \frac {10} {3}

Having "k", we find "y" when x = 6:

y = \frac {10} {3} (6)\\y = \frac {60} {3}\\y = 20

ANswer:

k = \frac {10} {3}\\y = 20

In a parallel circuit, ET = 120 V, R = 470 Ω, and XL = 500 Ω. What is the reactive power?
ddd [48]

Answer:

Reactive power is 28.8VARs

Step-by-step explanation:

We are given that in a parallel circuit, E_{T}=120V,R=470Ω and X_{L}=500Ω

And we area asked to find reactive power.

Reactive power is power dissipated due to reactive elements in the circuit and it occurs when voltage and current are not in phase.

Reactive power = \frac{E_{T}^{2}}{X_{L}}=\frac{120^{2}}{500}=28.8VARs
