Given the following arithmetic sequence find the formula.
Answer:
D. an = 4n
Step-by-step explanation:
The formula for finding a term of an arithmetic sequence is:
an = a1 + (n-1)d
where an is the nth term, a1 is the first term and d is the common difference between the terms.
To find d we can take any two adjacent terms and subtract one from the other. e.g. 8 - 4 = 4, 16-12 = 4 etc.
The common difference here is 4, and we can see that the first term of the sequence is also 4, therefore our formula now looks like this:
an = 4 + (n-1)4
Now we can just expand out the brackets to find the final answer:
an = 4 + 4n - 4
an = 4n

How to plot the graphFrom the question, we have the following parameters that can be used in our computation:
Graph of a line with a slope of 3/5
This means that
Slope = 3/5
And it also means that the equation is a linear equation
A linear equation is represented as
y = mx + c
Where
m = slope
i.e. m = 3/5
So, we have
y = 3/5x + c
Assume that c = 1
So, we have
y = 3/5x + 1
Hence, the equation is y = 3/5x + 1

How the Earth rotates around the sun and moon?
The Earth orbits the Sun and rotates around its own axis. The Moon orbits the Earth and is held in place by the Earth’s gravity. This is why the length of a day is gradually increasing over time.
The Moon’s gravitational pull causes the tides, which is why the ocean’s water level rises and falls. The gravitational pull of the Moon also affects the Earth’s rotation by slowing it down slightly. This is why the length of a day is gradually increasing over time.

You and your friend go to a taco truck for lunch. You order 3 soft tacos and 3 burritos and spend $11. 25. Your friend orders 4 soft tacos and 2 burritos and spends $10. 0
Therefore ,As a result, the answer to the provided equation is that a burrito costs $2.50 and a soft taco costs $1.50.
Define equation .A number, a variable, or a mix of both plus certain operation symbols make up an expression. An equal sign separates two expressions that make up an equation. Word illustration The product of 8 and 3 is 11.
Here,
Let the price of a soft taco be set at s.
Let b be the price for one burrito.
Therefore, we have this system.
3s + 3b = 11.25
4s + 2b = 10.00 (1) (1)
By multiplying the first equation by 3, we get that.
If s + b = 3.75, take b off of both sides.
s = 3.75 - b (2) (2)
Subtract (2) from (1) and you get
Simplify 4 (3.75 - b) + 2 b = 10.00.
15 - 4b + 2b = 10.00
Subtract 15 from both sides (-2b + 15 = 10) to get the total.
Divide both sides by -2 to get -2b = - 5.00.
b = 2.50
as well as (2)
s = 3.75 - 2.50 = 1.50
As a result, the answer to the provided equation is that a burrito costs $2.50 and a soft taco costs $1.50.

Miguel has three times as many dimes as he has quarters. He has as many nickels.as he has dimes and quarters.combined. The total amount of money he has is $3.00. How many of each coin does Miguel have?
Answer:
Step-by-step explanation:
fter solving the algebraic equation, Miguel has 4 quarters, 12 dimes and 16 nickels.
What is algebra?
One of the earliest areas of mathematics that deals with number theory, geometry, and analysis is algebra. Algebra is also defined as the study of mathematical rules and symbols through the manipulation of those mathematical symbols.
The number of quarters is taken to be x, then the number of dimes will be 3x, and the number of nickels will be 3x + x = 4x
$3.00 when converted to cents is 300 cents.
The value of nickels is 5 x 4x=20x.
The value of dimes is 10 x 3x=30x.
The value of quarters is 25x.
As the total value of money Miguel has is 300 cents, then the algebraic equation will be -
20x + 30x + 25x = 300
Solve to get the value of x -
75x = 300
x = 4
Therefore, the amount of quarters is x = 4 quarters.
The amount of dimes is x = 3x = 3 x 4 = 12 dimes.
The amount of nickels is 4x = 4 x 4 = 16 nickels.

So

This means the upper left angle of the top triangle measure is 58 becuase triangle interior theorem.

Which of these characteristics of a star make it most likely to become a black hole? Select the two correct answers.
A. Its mass is equal to that of the sun.
B. It has an abundant supply of hydrogen.
C. Its mass is greater than 20 times the mass of the sun.
D. It is dying.
The two characteristics of a star to become a black hole are:
Its mass is greater than 20 times the mass of the Sun.It is dying.The correct options are C and D.
When a star has consumed all its fuel (like hydrogen), that is to say, when it is at the end of its life, it can become a black hole. For this to happen, the mass of the star must be greater than 20 times the mass of the Sun. If a star is at the end of its life cycle but has a mass that is less than 20 times the Sun's mass, it will not become a black hole.
The given options:
A. Its mass is equal to that of the sun. False
Its mass must be greater than 20 times the mass of the Sun.
B. It has an abundant supply of hydrogen. False
When it has an abundant supply of hydrogen, the star is at the beginning or the middle of its life cycle, and to become into a black hole it must be at the end of it.
C. Its mass is greater than 20 times the mass of the Sun. True
Yes, its mass must be greater than 20 times the mass of the Sun.
D. It is dying. True
The star must have no more fuel to continue its life cycle.

Algorithms are data calculation and processing specifications. More advanced algorithms can use conditionals to divert code execution through various paths (referred to as automated decision-making) & deduce valid inferences (referred to as automated reasoning), eventually achieving automation.

The unknown number deduced by solving the equation 4x - 1 = 6x +9 is -5.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
Let the unknown number be x.
First multiply the number by 4 = 4x
Then subtract 1 from it = 4x -1
This results in the same number as when the number is multiplied by 6 and 9 is added to it = 6x + 9.
So the equation will be -
4x - 1 = 6x +9
4x - 6x = 9 + 1
-2x = 10
-x = 10/2
