Answer:

C y = 1/5x - 1

Step-by-step explanation:

Slope intercept form: y = mx + b where m = slope and b = y-intercept.

Substitute into the slope intercept form m= 1/5 and b = -1

In a parallel circuit, ET = 240 V, R = 330 Ω, and XL = 420 Ω. What is Z?

denis-greek [22]

Answer:

Z = 258Ω

Step-by-step explanation:

There are two methods of solving this question,

First method

Z = ( RXL)/ sqr rt ( R²+XL²)

Z= (330 Ω × 420 Ω)/ sqr rt ( 330 Ω² + 420 Ω²)

Z = 138600 Ω /534

Z = 259 Ω

THE second complete method is given in attachment below
