Firstly, we will draw
RL series circuit
ET = 120 V, R = 40 Ω, and XL = 30 Ω
Firstly, we will find current

now, we can plug values
and we get

now, we can find voltage across L

so, we get

now, we can find absolute value

Answer:
x = 1, -5.56
Step-by-step explanation:
x^2 = -7x - 8
shift -7x and -8 to the other side . Remember when u shift minus changes into plus.
x^2 + 7x + 8 = 0
using quadratic equation formula
in quadratic equation one value comes positive and other comes in negative
a = 1 , b = 7 and c = 8
taking positive sign
x = (-b +
) /2*a
x = (-7 +
) /2*1
x = (-7 +
) /2
x = (-7 +
)/ 2
x = -7 + 9 / 2
x = 2/2
x = 1
taking negative sign
(-b -
) /2*a
x = (-7 -
) /2*1
x = (-7 -
) /2
x = -7 -
/ 2
x = -7 - 4.12 / 2
x = -11.12/2
x = -5.56
therefore x = 1 , - 5.56
I think it is 8/17...
hope this helps!
Write an expression using multiplication and addition with a sum of 16:
