I know that real numbers consist of the natural or counting numbers, whole numbers, integers, rational numbers and irrational nu

ra1l [238]

The imaginary unit $i$ belongs to the set of complex numbers, denoted by $\mathbb C$ . These numbers take the form $a+bi$ , where $a,b$ are any real numbers.

The set of real numbers, $\mathbb R$ , is a subset of $\mathbb C$ , where each number in $\mathbb R$ can be obtained by taking $b=0$ and letting $a$ be any real number.

But any number in $\mathbb C$ with non-zero imaginary part is not a real number. This includes $i$ .

"is it possible that i can use an imaginary number for a real number"

I'm not sure what you mean by this part of your question. It is possible to represent any real number as a complex number, but not a purely imaginary one. All real numbers are complex, but not all complex numbers are real. For example, 2 is real and complex because $2=2+0i$ .

There are some operations that you can carry out on purely imaginary numbers to get a purely real number. A famous example is raising $i$ to the $i$ -th power. Since $i=e^{i\pi/2}$ , we have

$i^i=\left(e^{i\pi/2}\right)^i=e^{i^2\pi/2}=e^{-\pi/2}\approx0.2079$

Contact [7]

Answer:

x=-2, y=-4. (-2, -4).

Step-by-step explanation:

2x-y=0

y=x-2

------------

2x-(x-2)=0

2x-x+2=0

x+2=0

x=0-2

x=-2

y=-2-2=-4

A boat is marked up 20% on the original price the original price was 50$ what is the sale price of the boat before sales tax

AnnyKZ [126]

Answer:

$60

Step-by-step explanation:

We can create a proportion to find the markup from original price to the marked up price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. It is marked up by 20% so we pay 120% of $50.

$\frac{120}{100} =\frac{x}{50}$

We begin solving by cross multiplying numerator to denominator of each fraction.

$120(50)=100(x)\\6000=100x\\\frac{6000}{100}=\frac{100x}{100} \\60=x$

RoseWind [281]

Answer:

253.548 minutes which rounds to 254 minutes

1 hour = 60 minutes

4.2258 × 60 minutes = number of minutes per 4.2258 hours

253.548 minutes

The question does not specify how to round it so I will round to the nearest whole number: 254 minutes.
