Plugging that slope into the slope intercept formula, y =2x + b.
The constant b can be found by plugging in a point and solving for b.

How many different quantum states are possible if the principal quantum number is n = 4?
Answers
The possible quantum numbers for the value of n=4 will be i=0,1,2,3.
What is quantum number?
The number of elements in a quantum is the count of 0 to n - 1 where n is the principal quantum number. There are 4 different values of i in quantum number n =4.
Given that:
[tex]n=4[/tex] -- quantum number
To count the quantum numbers (i), we make use of the following set:
[tex]i=[0,1,2,3............n-1][/tex]
The value of n is: [tex]n=4[/tex]
So, the set will be populated as follows
[tex]i=(0,1,2,3)[/tex]
The number of elements in the set is 4.
This means that there are 4 different values of i

Answers
The horizontal distance from the base of the skyscraper out to the ship will be 1140 feet.
What is trigonometry?Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.
Given that:-
The angle is = 45The height of the skyscraper is 1140 feet.The horizontal distance will be calculated by applying the angle property in the right angle triangle.
tan45 = ( P / B )
B = P / tan45
B = P Since ( tan45 =1 )
B = 1140 feet.
Therefore the horizontal distance from the base of the skyscraper out to the ship will be 1140 feet.

Need help,will give 20 points.Use the rectangle to find the measure of the following angles measure ane BAC=25
Answers
1) All angles of a rectangle are right angles, so the measure of angle CBA is 90 degrees.
2) Since all angles of a rectangle are right angles, angle BAD measures 90 degrees. Subtracting the 25 degrees of angle BAW from this, we get that angle CAD has a measure of 65 degrees.
3) Opposite sides of a rectangle are parallel, so by the alternate interior angles theorem, the measure of angle ACD is 25 degrees.
4) Because diagonals of a rectangle are congruent and bisect each other, this means BW=WA. So, since angles opposite equal sides in a triangle (in this case triangle ABW) are equal, the measure of angle ABW is 25 degrees. This means that the measure of angle CBD is 90-25=65 degrees.
5) In triangle AWB, since angles in a triangle add to 180 degrees, angle BWA measures 130 degrees.
6) Once again, since diagonals of a rectangle are congruent and bisect each other, AW=WD. So, the measures of angles WAD and ADW are each 65 degrees. Thus, because angles in a triangle (in this case triangle AWD) add to 180 degrees, the measure of angle AWD is 50 degrees.

Major Axis: longest diameter of an ellipse
Minor Axis: shortest diameter of an ellipse
Major radius: one half of the major axis
Minor radius: one half of the minor axis
If a > b the ellipse is horizontal, a is the major radius, and b is the minor radius.
If b > a the ellipse is vertical and b is the major radius, and a is the minor radius.
Given equation:
[tex]\dfrac{(y-4)^2}{25}+\dfrac{x^2}{9}=1[/tex]
[tex]\implies \dfrac{x^2}{9}+\dfrac{(y-4)^2}{25}=1[/tex]
Comparing with the general equation:
h = 0a² = 9 ⇒ a = 3k = 4b² = 25 ⇒ b = 5As b > a then the ellipse is vertical and b is the major radius.
⇒ Major axis = 2 × Major Radius

you need to make 6000g of potato cakes. the ratio of potato, cheese and onion is 9:2:1. per every 175g of cheese = £2.25. how much will all of the cheese cost?
Answers
Let
potato be 9x,cheese be 2x and onion be x
9x+2x+x=600012x=6000x=500Cheese
2(500)1000gTotal 175gs
100/1755.714Total cost
5.714(2.25)£12.85Answer:
£12.86 (nearest pence)
Step-by-step explanation:
Given ratio:
potato : cheese : onion = 9 : 2 : 1Sum the ratios:
⇒ 9 + 2 + 1 = 12
Divide the total weight by the sum of the ratios:
⇒ 6000 g ÷ 12 = 500
Multiply each ratio by 500 to find the amount of each ingredient needed to make 6000 g of potato cakes:
⇒ potato = 9 × 500 = 4500 g
⇒ cheese = 2 × 500 = 1000 g
⇒ onion = 1 × 500 = 500 g
If 175 g of cheese costs £2.25, then 1000 g of cheese costs:
⇒ (2.25 / 175) × 1000 = £12.86 (nearest pence)

As per the question the length of the straw is equal to length of the diagonal of Rectangular box.
l= 3 inch , b= 5 inch , h= 1 inch
Let us consider the length of the straw be 'x'.
As, Diagonal of Cuboid is,
[tex]X^{2}= l^{2}+b^{2}+h^{2}[/tex]
[tex]X^{2}= 3^{2}+5^{2}+1^{2}\\X^{2}= 9+25+1\\X^{2}= 35\\X= \sqrt{35}[/tex]

tom is planning a party for five friends at a game arcade. He can buy different numbers of game tokens for the prices shown on the table
each friend will have 25 game tokens.
how much money could tom save, in dollars, if he buys all 125 tokens before the party rather than separately as each friends arrive?
Answers
Answer:
He can save 20 dollars
Step-by-step explanation:
He can buy one 100 token amount and one 25 token amount. This will cost 20 + 10 dollars, or 30 dollars. If each friend buys 25 tokens, it will cost
10 * 5 dollars, or 50 dollars. 50 - 30 = 20. So he can save 20 dollars.
