Answer:
Step by step explanation: OK so your question is 26.35×21.5 so that is pretty easy but if you do not know that you are in the right place so what you’re gonna do is if you have a calculator then you need to take that out if you don’t then I’m going to need a piece of paper now for me it’s easy because I have a calculator and you can find a calculator on your iPad your phone etc. but yeah so you’re gonna type in 26.35 Times 21.5 now I want u do that on your own once you type in those numbers you’re going to hit the = and it’s that simple and you’ll then get your answer so I hope that helped you to learn how you multiply those the numbers.
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)
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.

Answer:
A
Step-by-step explanation:
this is because a range is simply a collection of numbers that can be found in the domain
and since there is no domain, we assume that the numbers are all in the domain
leading us to our answer a
Answer:
2×sqrt(2) = 2.828427125...
Step-by-step explanation:
x = "a positive number"
x + 56/x = x³
x² + 56 = x⁴
x⁴ - x² - 56 = 0
(x² + 7)(x² - 8) = 0
this is true only for
x² = -7
or
x² = 8
x² = -7 would mean that x is an imaginary number. so, that is not a valid solution here.
x² = 8 means
x = sqrt(8) = sqrt(4×2) = 2×sqrt(2) = 2.828427125...
