Kc = [tex]\frac{[N_{2} O_{4}]}{[NO_{2}]^{2} }[/tex]

Concentration of NO2 = 11.95
Concebtration of N2O4 = 6.05
Based on the current concentrations of NO2 and N2O4, what is Kc?

Step 1: Define

[RxN]   2NO₂ ⇆ N₂O₄

[Equilibrium Rate Law]   [tex]\displaystyle K_c = \frac{[N_2O_4]}{[NO_2]^2}[/tex]

NO₂ = 11.95 M

N₂O₄ = 6.05 M

This value of K tells us that the reactants are favored in the equilibrium reaction (K < 0.1).

Jayanti takes shortest route to her home by walking diagonally across a rectangular park. The park measures 60 meters ×80 meters. How much shorter is the root across the park than the route around its edges?

Pls help!!! It's due today in about 6 hours!!!!! I would also like a proper explanation instead of the answer itself!!!!

Answers

Answer:

The route across the park is 40 meter shorter than the route around its edges.

Step-by-step explanation:

We have to calculate the distance for both routes

As the route around the edges is straight,  we have to find the sum of length of both edges

Let [tex]R_E[/tex] be the distance of route around edges

[tex]R_E = 80+60 = 140\ meters[/tex]

Now we know that a diagonal divides a rectangle in two right angled triangles in which the diagonal is the hypotenuse.

We can use Pythagoras theorem to find the length of the diagonal

So,

[tex]H^2 = P^2 + B^2[/tex]

In the given scenario

P = 60

B = 80

Now

[tex]H^2 = (60)^2 + (80)^2\\H^2 = 3600+6400\\H^2 = 10000\\\sqrt{H^2} = \sqrt{10000}\\H = 100\ meters[/tex]

In order to calculate that how much shorter is the path across the park, we have to subtract the distance across park from the distance across edges.

[tex]= 140-100 = 40\ meters[/tex]

Hence,

The route across the park is 40 meter shorter than the route around its edges.

Explanation:

y=-x+4 is the Equation of the Line Passes through the points (-4,8) and (1,3).

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The slope of line passing through points (-4,8) and (1,3)

m=3-8/1+4

=-5/5=-1

Now we need to find the y intercept

8=-1(-4)+b

8=4+b

b=4

Hence, y=-x+4 is the Equation of the Line Passes through the points (-4,8) and (1,3).

[tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex]

Step-by-step explanation:

Last year there were m members in a photography club.This year the number of members has increased by 10%m + 0.1m represents the number of members in the club this year.

So m represents the number of members in the club last year.

A 10% increase of the members = [tex]\frac{10}{100} * m[/tex] = 0.1m

Hence the number of members in the club this year = m + 0.1m

Answer:

-1 -9i, where a = -1 and b = -9

Step-by-step explanation:

1st step is to open up the brackets. Since there's a (-) in front of the second bracket, we have to multiply every term by -1, so positive becomes negative, negative becomes positive etc.

4-i-5-8i

Then we collect like terms.

-1 -9i

This is the answer. It looks wrong since the variables are 'positive' in a +bi, but you have to remember that a variable can be represented as a, but its actual value could be negative, in this case -1. This is the same with b, as b could be the same as -9.

This is an expression, so we can't multiply everything by -1 to make it 'look right'. You can only multiply by -1 or 'alter' the terms when the expression equates to something.

Answers

All the angles in a circle equal to 360 degrees. So basically just add up all the known values: 23+23+15=61 and then subtract that from 360: 360-61=299.

You can also do 23+23+15+x=360. Adding it all becomes 61+x=360, subtract 61 from both sides of the equation, and you get x=299.

(Something to help remember is that the angle is obtuse, meaning it’s automatically more than 90 degrees, hope this helps!)

NEGORE, THE COWARDHe had followed the trail of his fleeing people for eleven days, and his pursuit had been in itself a flight; for behind him he knew full well were the dreaded Russians, Negore fled after his fleeing tribe and came upon it this summer night by the head waters of the Pee-lat. Though near the midnight hour, it was bright day as he passed through the weary camp. Many saw him, all knew him, but few and cold were the greetings he received."Negore, the Coward," he heard Illiha, a young woman, laugh, and Sun-ne, his sister's daughter, laughed with her.Black anger ate at his heart; but he gave no sign, threading his way among the camp-fires until he came to one where sat an old man. A young woman was kneading with skillful fingers the tired muscles of his legs. He raised a sightless face and listened intently as Negore's foot crackled a dead twig."Who comes?" he queried in a thin, tremulous voice."Negore," said the young woman, scarcely looking up from her task.Negore's face was expressionless. For many minutes he stood and waited. The old man's head had sunk back upon his chest. The young woman pressed and prodded the wasted muscles, resting her body on her knees, her bowed head hidden as in a cloud by her black wealth of hair. Negore watched the supple body, bending at the hips as a lynx's body might bend, pliant as a young willow stalk, and, withal, strong as only youth is strong. He looked, and was aware of a great yearning, akin in sensation to physical hunger. At last he spoke, saying:"Is there no greeting for Negore, who has been long gone and has but now come back?""Thou art my woman, Oona," Negore said, his tones dominant and conveying a hint of menace.She arose with catlike ease and suddenness to her full height, her eyes flashing, her nostrils quivering like a deer's."I was thy woman to be, Negore, but thou art a coward; the daughter of Old Kinoos mates not with a coward!""Old Kinoos and I came among you from a strange land. Thy people took us in by their fires and made us warm, nor asked whence or why we wandered. It was their thought that Old Kinoos had lost the sight of his eyes from age; nor did Old Kinoos say otherwise, nor did I, his daughter. Old Kinoos is a brave man, but Old Kinoos was never a boaster. And now, when I tell thee of how his blindness came to be, thou wilt know, beyond question, that the daughter of Kinoos cannot mother the children of a coward such as thou art, Negore."Again she silenced the speech that rushed up to his tongue."Know, Negore, if journey be added unto journey of all thy journeyings through this land, thou wouldst not come to the unknown Sitka on the Great Salt Sea. In that place there be many Russian folk, and their rule is harsh. And from Sitka, Old Kinoos, who was Young Kinoos in those days, fled away with me, a babe in his arms, along the islands in the midst of the sea. My mother dead tells the tale of his wrong; a Russian, dead with a spear through breast and back, tells the tale of the vengeance of Kinoos."But wherever we fled, and however far we fled, always did we find the hated Russian folk. Kinoos was unafraid, but the sight of them was a hurt to his eyes; so we fled on and on, through the seas and years, till we came to the Great Fog Sea"At last we came to Pastolik, which is where the Yukon drowns itself in the Great Fog Sea."So, when there came a ship, Old Kinoos stepped forward and said he would show the way. He was an old man then, and his hair was white; but he was unafraid. And he was cunning, for he took the ship to where the sea sucks in to the land and the waves beat white on the mountain called Romanoff. The sea sucked the ship in to where the waves beat white, and it ground upon the rocks and broke open its sides. Then came all the people of Pastolik, (for this was the plan), with their war-spears, and arrows, and some few guns. But first the Russians put out the eyes of Old Kinoos that he might never show the way again, and then they fought, where the waves beat white, with the people of Pastolik."Now the head-man of these Russians was Ivan. He it was, with his two thumbs, who drove out the eyes of Kinoos. He it was who fought his way through the white water, with two men left of all his men, and went away along the rim of the Great Fog Sea into the north. Kinoos was wise. He could see no more and was helpless as a child. So he fled away from the sea, up the great, strange Yukon, even to Nulato, and I fled with him."This was the deed my father did, Kinoos, an old man.
