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.

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.
Explanation: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:
Price per kilogram = Total cost / Total weight in kgPrice per kilogram = 525 rubles / 7 kg = 75 rubles/kgNow, we multiply the price per kilogram by the desired weight to get the total cost for 4.6 kg:
Total cost for 4.6 kg = Price per kilogram * Weight of the pearsTotal cost for 4.6 kg = 75 rubles/kg * 4.6 kg = 345 rublesTherefore, one would need to pay 345 rubles for 4.6 kg of pears.

You have purchased a 42 inch television with an aspect ratio of 16:9. You want to watch a movie which has an aspect ratio of 1.85:1. Find the following measurements & show all work: 1. Height of the television screen 2. Width of the television screen 3. Height of the black bars at the top and bottom of the screen. 4. Percent of the area of the television screen that is covered by the image.
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.
Explanation: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%

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.
