Let x = 2 + 8i and xy = –2 + 26i. What is y?

Answer: 3+i

Answer 1

Answer:

3 + i

Step-by-step explanation:

Let X = 2 + 8i And Xy = 2 + 26i. What Is Y?Answer: 3+i

Answer 2

The solution for the complex function is equal to y = 3 + i.

What is a complex function?

The function which is made up of the real numbers, as well as imaginary numbers, are called complex numbers these numbers are represented by a +ib form where the first part is the real part and the second part is the imaginary form.

The given complex functions are x = 2 + 8i and xy is -2+ 26i. The value of y will be calculated as below:-

xy = -2+ 26i.

y = ( -2+ 26i ) / x

y = ( -2+ 26i ) / ( 2 + 8i )

The value of the function will be calculated by rationalizing the function. When p and q are integers and q is not equal to zero, a result is a rational number, which has the form p/q. This ratio is between two integers.

The fundamental distinction between a fraction and a rational number is that fractions are always positive while rational numbers can be either positive or negative.

[tex]y =\dfrac{-2+26i}{2+8i} = \dfrac{-1+3i}{1+4i}[/tex]

[tex]y =\dfrac{-1+3i}{1+4i}\times \dfrac{1-4i}{1-4i}[/tex]

[tex]y = \dfrac{-1+4i+13i+52}{1+16}[/tex]

[tex]y = \dfrac{17i+51}{17}[/tex]

y = 3+i

Therefore, the solution for the complex function is equal to y = 3 + i.

Tell whether the angles are complementary or supplementary. Then find the value of x

Answers

Answer:

Complementary, x=78

Step-by-step explanation:

90= (x-8)+20

complementary angles add up to 90 degrees.

Answer:

Complementary, x is 78

Step-by-step explanation:

Let's first define what complementary and supplementary angles are. Complementary angles add up to 90 degrees, and supplementary add up to 180. From this image, we can see that this is a right angle. Right angles add up to 90 degrees, therefore, this is a complementary angle.

Now, because we know that it is 90 degrees and that (x-8)+(20) = 90, then we can solve for x. However, if the angle is unknown, then we would do x-8=20. In this case, sense we know for sure this angle is complementary, we do

(x-8)+(20) = 90

X+12=90 We combined like terms

X=78 Inverse operations

You can plug 78 into x and check to see if it is correct if they are 90 degrees total.

Problem:

Craig earns extra money as a lifeguard. He earns $37 for 4 hours and $64.75 for 7 hours.

Answers

Answer:

The answer is: y = 9.25x

Step-by-step explanation:

Let the equation for the proportionality relation is y = mx .......... (1), where y represents the money that Craig earns for a duty of x hours.

Here, m is the constant of proportionality and we have to find its value.

Given that Craig earns $37 for 4 hours duty.

So, from equation (1), we have 37 = 4m, ⇒ m = 9.25

Therefore, the equation becomes y = 9.25x. (Answer)

In a sixth grade class the ratio of boys to girls is 4:3 if there are 35 students in the class how many girls are there

Answers

Answer:

The given ratio is 3:4 this means there are 7 people in each unit of this ratio.

It is stated that there are 35 students in total . That would mean that there are

5 Total sets of students in this class . When we multiply the numbers in our starting ratio by this multiple of 5 , our ratio now becomes 15 : 20

15 and 20 do indeed add up to 35 … But , our question wants to know how many more GIRLS are in the class . Boys were calculated to be 15 in number .

Girls were calculated to be 20 in number .

We now know there were 5 more girls than boys in that class ..

5 is your answer .

total number of student in class=35

let the number of boys be 3x

let the number of girls be 4x

so therefore 3x+4x=35 =>7x=35 =>x=5

so therefore number of boys in class is 3x=>3(5)=15

and number of girls in class is 4x=>4(5)=20

so there are 20–15=5 more girls in class than boys.

Let the number boys in the class be b. So b/(35-b)=3:4, or 105-3b=4b, or 7b=105, or b=15. The number of girls in the class is 35-15=20 20-15=5

Ans: there are 5 more girls than the number of boys in the class.

The line is straight, so the 2 angles have to equal 180. Since we already know one angle is 21 degrees, we can subtract that from 180 to find the measure of the second angle. 180-21=159
So the measure of the other angle is 159 degrees.

Select all intervals in which the function P(t) is decreasing

Answers

Answer:

we conclude that the intervals in which the function P(t) is decreasing are:

x < 13 < x < 4

Step-by-step explanation:

At x< 1, the function P(t) is decreasing

A function p is an increasing function on an open interval if f(y) > f(x) for any two input values x and y in the given interval where y>xA function p is a decreasing function on an open interval if f(y) > f(x) for any two input values x and y in the given interval where y>x

From the figure, it is clear that the function seems to be increasing

from (1, 3) and then 4 to onwards.

But it is clear that the function seems to be decreasing from the x < 1 and from the interval (3, 4).

Therefore, we conclude that the intervals in which the function P(t) is decreasing are:

x < 13 < x < 4

Water flows from a faucet at a constant rate. Kian
measures 8 cups of water in 6 seconds.
What is the constant of proportionality for the relationship of cups of water to minutes?

Answers

Answer:

4 cups every 3 second which means so 80 cuos in one minute

Step-by-step explanation:

hope this helps

The constant of proportionality for the relationship of cups of water to minutes is 80

Represent cups with c and time with t.

So, the given parameter can be represented using the following ratio

c : t = 8 : 6

Multiply by 10

c : t = 80 : 60

60 seconds = 1 minutes.

So, we have:

c : t = 80 : 1

Express as fractions

[tex]\mathbf{\frac ct = \frac{80}1}[/tex]

Multiply both sides by t

[tex]\mathbf{\frac ct = 80}[/tex]

Multiply both sides by 6

[tex]\mathbf{c = 80t}[/tex]

A proportional equation is represented as:

[tex]\mathbf{c= mt}[/tex]

Where m represents the constant of proportionality

By comparison:

[tex]\mathbf{m = 80}[/tex]

Hence, the constant of proportionality is 80

Sorry Guys, Angle 12 & 10 are effectively corresponding angles, but angle 10 & 7 are alternate interior angles. Anyways, Angle 12 & 10 are congruent and 10 & 7 are congruent. At the end, the three angles 12, 10, and 7 have the same measure. If we put it otherwise, the line B is intersecting line D which form right angles equals to 90 degrees, so angle 12 = 90, and the same happens with angle 10 and 7, so the three angles are congruent, but at the same time, angle 7 is supplementary with angle 12 because their sum is equal to 180, (90 + 90 = 180). If you think from different angles is hard to choose the right answer, so what I guess is that we don't need to take into account the angle 10, just the fact that line A intersect line C, and Line B intersect line D forming right angles, and that angle 7 and 12 are right angles which sum equals 180, therefore, we could say that they are supplementary angles, but also congruent because they measure the same, so at the end, I don't know what answer to choose. Both seems correct to me.
