Answer:

Quadratic equations have the form:

ax^2 + bx + c = 0

So, a = 1 b = -3 and c = -2

None of the 4 choices have "a" equal to one.

Please help! If the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms, what is the voltage?
Leona [35]

The value of the voltage is 18 - j volts if the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms option (c) is correct.

<h3>What is a complex number?</h3>

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have:

The current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms.

As we know,

V = IR

V = (3 + j2)(4 - j3)

\rm V=\left(3\cdot \:4-2\left(-3\right)\right)+\left(3\left(-3\right)+2\cdot \:4\right)j

j² = -1 (complex part)

After simplification:

V = 18 - j  volts

Thus, the value of the voltage is 18 - j volts if the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms option (c) is correct.

Vishal's phone plan costs $45.37 per month plus $0.60 per text message. How many text messages can he send and keep his monthly
Liono4ka [1.6K]

Answer:

56 messages.

Step-by-step explanation:

So, from the $79 you subtract $45.37, which results in $33.63. That is the amount he has left for the text messages. So, you divide $33.63 by 0.60c, which results in 56.05. However, you cannot have a .05 of a text message, so it rounds to 56 messages.

Hope I helped!!
