if (x+yi)+2(3x-y)+4i-0;then the value of x and y is
Answers
Answer:
X=0 and Y= 4(2i-1)/5
Step-by-step explanation:
Here is my solution, assuming that the equation equals 0. For y, just remember the definition of complex numbers and multiply by its conjugate.
The value of x and y are -8/7 and -4 respectively if (x + yi) + 2(3x - y) + 4i = 0.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have a complex number:
(x + yi) + 2(3x - y) + 4i = 0
After arranging:
x + yi + 6x - 2y + 4i = 0
7x - 2y + yi + 4i = 0
7x - 2y + (y + 4)i = 0
7x - 2y = 0
y + 4 = 0
This is the linear equation in two variables:
Plug y = -4 in the other equation:
7x - 2(-4) = 0
7x = -8
x = -8/7
y = -4
Thus, the value of x and y are -8/7 and -4 respectively if (x + yi) + 2(3x - y) + 4i = 0.

Property of a rhombus:
In a rhombus, the diagonals are perpendicular.
The sum of the measures of the angles of a triangle is 180 deg.
Since the diagonals are perpendicular, the angles formed by the intersection of the diagonals are right angles and measure 90 deg.
m<ABD + m<CAB + 90 = 180
50 + m<CAB + 90 = 180
m<CAB + 140 = 180
(i) m<CAB = 40
The diagonals of a rhombus divide the rhombus into 4 congruent triangles.
Call the point of intersection of the diagonals E.
Triangles CEB and AEB are congruent.
m<BCA = m<DCA = 40
m<BCD = m<BCA + m<DCA = 40 + 40
(ii) m<BCD = 80
m<CDB = m<ADB = 50
m<ADC = m<CDB + m<ADB = 50 + 50
(iii) m<ADC = 100
10.
There are two angles labeled z. One is near point E and one is near point O. One of them probably is x.
Two angles measure 60 and 80. Add them to get 140.
z (near point O) and the 140 deg angle are a linear pair. their measures add to 180 deg.
z + 140 = 180
z = 40 (This is the z near point O.)
z (near point O) and 60 deg add to an interior angle of the parallelogram.
z + 60 = 40 + 60 = 100
The interior angle at vertex O measures 100 deg.
Adjacent interior angles of a parallelogram are supplementary.
100 + y = 180
y = 80
The two angles labeled z are alternate interior angles. Since the sides of a parallelogram are parallel, the two angles labeled z are congruent and measure 40 deg.
z = 40 (This is angle z near point E)

If you have 10 million particles of pollutant per gallon originally, how many filters would the water need to be passed through to reduce the pollutant to below 500 particles per gallon? You can only use a whole number of filters.
Answers
Answer:
5 filters
Step-by-step explanation:
1 filter = 1 million remain
2 filter =100,000 remain
3 filter =10,000 remain
4 filter =1,000 remain
5 filter = 100 remain which is below to 500
To reduce the pollutant to below 500 particles per gallon, the water would need to be filtered through 13 filters.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
Let's first define a variable, p, to represent the number of filters. We can then say that the number of particles remaining in the water after the first filter is applied is 0.9 x 10,000,000 = 9,000,000 particles per gallon.
After the second filter is applied, the number of particles remaining is 0.9 x 9,000,000 = 8,100,000 particles per gallon, and so on.
This equation would be [tex]0.9^p \times 10,000,000[/tex]. We want to find the smallest value of p that makes this expression less than 500.
We can solve this by setting the expression equal to 500 and solving for p. This gives us the equation [tex]0.9^p \times 10,000,000=500[/tex].
Solving for p, we get p = log(500/10,000,000) / log(0.9), which is approximately 12.39.
Since we can only use a whole number of filters,
Thus, we would need to use 13 filters to reduce the pollutant to below 500 particles per gallon.

Step-by-step explanation:
Apply the property of absolute values: if [tex]a \ge 0[/tex], then [tex]|x| \le a \iff -a \le x \le a[/tex]. By this property, [tex]|- 3\, h - 6 | \le 3[/tex] is equivalent to [tex]-3 \le -3\, h - 6\le 3[/tex]. That's the same as saying that [tex]-3\, h - 6 \ge -3[/tex] and [tex]-3\, h - 6 \le 3[/tex].

[tex]-3\, h \ge 3[/tex] and [tex]-3\, h \le 9[/tex].
Divide both sides of both inequalities by [tex](-3)[/tex]. Note that because [tex]-3 < 0[/tex], dividing both sides of an equality by this number will flip the direction of the inequality sign.
[tex]-3\, h \ge 3[/tex] would become [tex]h \le -1[/tex].[tex]-3\, h \le 9[/tex] would become [tex]h \ge -3[/tex].Both inequalities are supposed to be true. Combining the two inequalities to obtain:

A parallelogram has two sides parallel and equal meaning the top and bottom length are the same;
Meaning if the top is C, the bottom is C.
Similarly the length at the right side equals that on the left;
That means the the left = 60.4ft
Perimeter means distance round
And perimeter =157.6ft
Meaning if we start from the Top, it means:
C+ 60.4ft + C + 60.4ft= 157.6ft
C + C + 60.4ft+ 60.4ft = 157.6ft
2C + 120.8 = 157.6
2C = 157.6 - 120.8
2C= 36.8
C = 36.8/2
C= 19.4ft

Answer:
The average rate of change in the balance over the interval t = 0 to t = 5 is of $20.82 a year. This means that the balance increased by $20.82 a year over the interval t = 0 to t = 5.
Step-by-step explanation:
Given a function y, the average rate of change S of y=f(x) in an interval [tex](x_{s}, x_{f})[/tex] will be given by the following equation:
[tex]S = \frac{f(x_{f}) - f(x_{s})}{x_{f} - x_{s}}[/tex]
In this problem, we have that:
[tex]B(t) = 1000(1.02)^{t}[/tex]
Find the average rate of change in the balance over the interval t = 0 to t = 5.
[tex]B(0) = 1000(1.02)^{0} = 1000[/tex]
[tex]B(5) = 1000(1.02)^{5} = 1104.08[/tex]
Then
[tex]S = \frac{1104.08 - 1000}{5-0} = 20.82[/tex]
The average rate of change in the balance over the interval t = 0 to t = 5 is of $20.82 a year. This means that the balance increased by $20.82 a year over the interval t = 0 to t = 5.

Producția de carne pe animal obținută de la un porc de rasă non-superioară = 4,8 kg de carne pe o rasă de porc non-superioară.
Step-by-step explanation:
English Translation
A quarter of the number of pigs on the farm, being of superior breed, bring at the end of the year, on average, a production of 9.6 kg of meat per animal. The production thus obtained represents half of total meat production, Determine the meat production per animal obtained from a non-superior breed pig.
Solution
Let the meat production per animal for the non superior breed of pig be y
Let the total number of pigs be x
A quarter of the pigs are superior breed, 0.25x, bring in 9.6 kg of meat per superior breed of pigs.
Total amount of meat produced by the superior breed of pigs = 0.25x × 9.6 = (3.6x) kg
This means that there are three quarter pigs from the less superior breed, 0.75x, making y kg of meat per animal.
Total amount of meat produced by the non superior breed of pigs = 0.75x × y = 0.75xy kg
Total meat production = (3.6x + 0.75xy) kg
It is then given that the total amount of meat from the superior breed is half of the total meat production.
That is,
3.6x = (3.6x + 0.75xy)/2
7.2x = 3.6x + 0.75xy
7.2x - 3.6x = 0.75xy
3.6x = 0.75xy
y = (3.6/0.75) = 4.8 kg
Hence, the meat production per animal obtained from a non-superior breed pig = 4.8 kg of meat per non superior breed of pig.
In Romanian/In limba romana
Permiteți producția de carne pe animal pentru rasa non superioară de porc
Fie numărul total de porci x
Un sfert din rasa superioară, 0,25x, aduce 9,6 kg de carne pentru fiecare rasă superioară de porci.
Un sfert din porci sunt de rasa superioară, 0,25x, aduc 9,6 kg de carne pe rasă superioară de porci.
Cantitatea totală de carne produsă de rasa superioară de porci = 0,25x × 9,6 = (3,6x) kg
Aceasta înseamnă că există trei sferturi de porci de la rasa mai puțin superioară, 0,75x, ceea ce face y kg de carne pe animal.
Cantitatea totală de carne produsă de rasa non superioară de porci = 0,75x × y = (0,75xy) kg
Producția totală de carne = (3,6x + 0,75xy) kg
Se consideră că cantitatea totală de carne de la rasa superioară este jumătate din producția totală de carne.
Acesta este,
3,6x = (3,6x + 0,75xy) / 2
7,2x = 3,6x + 0,75xy
7,2x - 3,6x = 0,75xy
3,6x = 0,75xy
y = (3,6 / 0,75) = 4,8 kg
Prin urmare, producția de carne pe animal obținută de la un porc de rasă non-superioară = 4,8 kg de carne la o rasă de porc ne superioară.
Hope this Helps!!!
Sper că acest lucru vă ajută!!!
