which expression represents purely real numbers and which expression represents non-real complex number?​

Answers

Answer 1

Incomplete question. However, I provided some explanation about non-real complex numbers.

Explanation:

In Mathematics, the term complex numbers (non-real complex numbers) in simple terms refers to numbers that containing an imaginary addition to it.

For example, the numbers 3i, 3 + 5i, 3i/4 are non-real numbers because of the addition of an imaginary part which is denoted by 'i'.

While real numbers, on the other hand, are numbers that do not include an imaginary part; they stand on their own, such as whole numbers 0, 1, 2, 3, etc, rational numbers like 3/4, etc.

Answer:

c ≈ 5.83095189485

Step-by-step explanation:

We can use the Pythagorean Theorem [tex](a^{2} +b^{2} =c^{2} )[/tex] for these kinds of problems.

So, pretend that line is the hypotenuse of a right triangle. One side would be

3 units long and another would be 5 units long. Let's plug that into the theorem.

3² + 5² = c²

Simplify.

9 + 25 = c²

Add.

34 = c²

And now square root both sides.

√34 = c

c ≈ 5.83095189485

When Sergio went to dinner with his brother, the bill was $51.19. What was the total they paid if they left a 15% tip?

Answers

Answer:

The total they paid was $58.8685

Step-by-step explanation:

Let us solve the question using the percentage method

∵ Sergio went to dinner with his brother

∵ The bill was $51.19

∵ They left a 15% tip

→ That means they pay extra money 15% of $51.19

The total they paid = the bill + 15% of the bill

∵ 15% of the bill = 15% × 51.19

→ Change 15% to a decimal by divide it by 100

∴ 15% of the bill = [tex]\frac{15}{100}[/tex] × 51.19

∴ 15% of the bill = 0.15 × 51.19

15% of the bill = $7.6785

→ Substitute it in the total they paid

∵ The total they paid = 51.19 + 7.6785

∴ The total they paid = $58.8685

The total they paid was $58.8685

(-4,6), slope=-1

Write the slope-intercept equation using the given information.

Answers

Answer:

y = -x +2

Step-by-step explanation:

y = mx + b

y=6

x=-4

m=-1 (m is the slope)

b=? (b is the y-intercept)

Putting these numbers into this equation,

6 = -1(-4) + b

b=6-4

b=2

So the equation is y = -1x + 2

or just y = -x +2
