What are the real and imaginary parts of the complex number? −6−i Enter your answers in the boxes. The real part: The imaginary part:
Answer:
Real part = -6 and imaginary part = -i
Step-by-step explanation:
A complex number can be written as a + bi,
where both a and b are real numbers,
While, i is an imaginary number ( equals to √-1, because √-1 does not defined as a real number ),
The product of a real number and imaginary number is imaginary number,
∴ bi is called imaginary part of a + bi
Also, a is real number ⇒ a is real part of a + bi
Here, the given complex number,
-6-i
By comparing,
Imaginary part = -i, real part = -6.
We want to see the real and imaginary parts of a given complex number.
The real part is: -6
The imaginary part is: -1
A general complex number is written as:
z = a + b*i
Where a is the real part and b is the imaginary part.
In this case, we have the number:
z = -6 - i
We can rewrite this as:
z = -6 + (-1)*i
Then the real part is the number that is alone, in this case, -6.
The imaginary part is the coefficient that multiplies the "i", which is -1.

On average nick walks 18000 steps every day he walks 1 mile every 3500 steps work out an estimate for the average distance in miles that nick walks in one year
Final answer:
To find the average distance Nick walks in a year, divide 18,000 steps by 3,500 steps per mile to get 5.14 miles per day, and then multiply by 365 days to estimate around 1,876.1 miles annually.
Explanation:
To estimate the average distance in miles that Nick walks in one year, we need to start with the information that Nick walks 18,000 steps every day and that he walks 1 mile every 3,500 steps. First, we need to calculate the number of miles Nick walks each day by dividing the total daily steps by the number of steps per mile:
Daily miles = 18,000 steps/day ÷ 3,500 steps/mile = 5.14 miles/day (rounded to two decimal places)
Next, we will calculate Nick's annual walking distance by multiplying the miles per day by the number of days in a year (365):
Annual distance = 5.14 miles/day × 365 days/year = 1,876.1 miles/year (rounded to one decimal place)
Therefore, we can estimate that Nick walks approximately 1,876.1 miles in one year.

Which expression is equivalent to
Multiply (8 + 3i)(3 + 5i).
Answer:
15i² + 49i + 33.
Step-by-step explanation:
Given : (8 + 3i)(3 + 5i).
To find : Multiply .
Solution : We have given (8 + 3i)(3 + 5i).
Distribute 8 over (3 + 5i) and 3i over (3 + 5i).
8 (3 + 5i) + 3i(3 + 5i).
8 *3 + 8 * 5i + 3 *3i + 3i *5i.
24 + 40 i + 9i + 15 i².
Combine like terms
24 + 9i +40i + 15i².
24 + 49i + 15i².
Therefore,15i² + 49i + 33.

Find the sum of the first 30 terms of the sequence, An = 3n + 2
Answer:
The sum of the first 30 terms of the sequence [tex]\( A_n = 3n + 2 \)[/tex] is 1455.
Explanation:
To find the sum of the first 30 terms of the sequence [tex]\( A_n = 3n + 2 \),[/tex] we need to substitute the values of [tex]\( n \)[/tex] from 1 to 30 into the formula and then add them together.
The formula for the [tex]\( n \)[/tex]th term of the sequence is [tex]\( A_n = 3n + 2 \).[/tex]
Let's find the first 30 terms of the sequence:
[tex]\[ A_1 = 3(1) + 2 = 5 \][/tex]
[tex]\[ A_2 = 3(2) + 2 = 8 \][/tex]
[tex]\[ A_3 = 3(3) + 2 = 11 \][/tex]
[tex]\[ \vdots \][/tex]
[tex]\[ A_{30} = 3(30) + 2 = 92 \][/tex]
Now, we need to find the sum of these terms:
[tex]\[ \text{Sum} = A_1 + A_2 + A_3 + \ldots + A_{30} \][/tex]
To find the sum, we can use the formula for the sum of an arithmetic series:
[tex]\[ \text{Sum} = \frac{n}{2}(A_1 + A_{30}) \][/tex]
Where:
- [tex]\( n \)[/tex] is the number of terms (30 in this case)
- [tex]\( A_1 \)[/tex] is the first term (5)
- [tex]\( A_{30} \)[/tex] is the 30th term (92)
Now, let's calculate the sum:
[tex]\[ \text{Sum} = \frac{30}{2}(5 + 92) \][/tex]
[tex]\[ \text{Sum} = \frac{30}{2}(97) \][/tex]
[tex]\[ \text{Sum} = 15 \times 97 \][/tex]
[tex]\[ \text{Sum} = 1455 \][/tex]
