Final answer:
The width of the field is 80 feet, and the length is 720 feet, calculated using the perimeter formula and the given ratio of length to width.
Explanation:
To determine the dimensions of the rectangular field, we need to set up two equations based on the given information that the field's length is nine times its width and that the perimeter is 1600 feet. We'll let w represent the width of the field and l represent the length.
Since the field's length is nine times its width, we can express this as l = 9w. The perimeter P of a rectangle is given by P = 2l + 2w. Since we know the perimeter is 1600 feet, we can use this to create the equation 1600 = 2(9w) + 2w, which simplifies to 1600 = 18w + 2w.
Combining like terms gives us 1600 = 20w, and solving for w gives us w = 1600 / 20, so w = 80 feet. Knowing w, we can find l by multiplying the width by 9: l = 9w = 9 × 80 = 720 feet.
Therefore, the dimensions of the field are a width of 80 feet and a length of 720 feet.

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]

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.

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.
