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.

11 = -d+15

subtract 15 from each side

-4 = -d

 divide both sides by -1

d = 4

Answer: 345 руб.

Step-by-step explanation:

525 : 7 = 75 (руб.) - стоимость 1 кг груш.

4,6 * 75 = 345 (руб.) - следует заплатить за 4,6 кг груш.

To find out how much to pay for 4.6 kg of pears, calculate the price per kilogram from the given 7 kg cost (525 rubles) and multiply by 4.6 kg, resulting in a price of 345 rubles for 4.6 kg.

The cost for 7 kg of pears is 525 rubles. To determine how much one should pay for 4.6 kg of pears, we use a simple proportion based on the principle that the price per kilogram remains constant.

First, we find the price per kilogram by dividing the total cost by the weight:

Now, we multiply the price per kilogram by the desired weight to get the total cost for 4.6 kg:

Therefore, one would need to pay 345 rubles for 4.6 kg of pears.

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.

Step-by-step explanation:

it rounds to 132.40 and B-D round to 132.30

The TV's width and height are approximately 36.61 inches and 20.55 inches respectively. The black bar's height is approximately 1.29 inches each. The movie covers almost 87.4% of the TV's screen area.

This question involves the use of ratios and some geometry. Your TV's aspect ratio of 16:9 essentially means the width is 16 parts and the height is 9 parts. And, the total diagonal is given 42 inches.

1. Using Pythagorean theorem a² + b² = c² where c is the hypotenuse (diagonal), the width and height of the TV can be found: height(h)= ratio_height * √(c²/(ratio_width² + ratio_height²)) = 9 * √(42²/(16² + 9²)) ≈ 20.55 inches.

2. Similarly for width(w): w= ratio_width * √(c²/(ratio_width² + ratio_height²)) ≈ 36.61 inches.

3. The movie's aspect ratio is 1.85:1. The height of the black bars can be calculated using ratio of the heights of the movie and the TV: black bar height= (h - w/1.85) / 2 ≈ 1.29 inches. This height is subtracted from the TV's height because the movie with ratio 1.85:1 is wider than 16:9 TV.

4. The percentage coverage is given by (w * (h - 2* black bar height)) / (w * h) ≈ 0.874 or 87.4%

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]

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.
