18+7(n-3)

=======================================================

Explanation:

We can rewrite the right hand side of choice C like so

18+7(n-3)

18+7(n-1-2)

18+7(n-1)+7(-2)

18+7(n-1)-14

4+7(n-1)

Which is now in the form a+d(n-1)

This confirms choice C to be arithmetic. The other choices cannot be written in the format of a+d(n-1). Choices A and B are quadratic sequences while choice D is exponential.

The first few terms of choice C are: 4, 11, 18, 25, 32, ...

To get new terms, add 7 to the previous one.

-------------

Notice how if n = 5 for instance, then,

[tex]a_n = 4+7(n-1)\\\\a_5 = 4+7(5-1)\\\\a_5 = 32\\\\[/tex]

and

[tex]b_n = 18+7(n-3)\\\\b_5 = 18+7(5-3)\\\\b_5 = 32\\\\[/tex]

This confirms that [tex]a_n = b_n[/tex] when n = 5. I'll let you check other positive integer values for n.

Answer:

[tex]\textsf{c)} \quad s_n=18+7(n-3)[/tex]

Step-by-step explanation:

An arithmetic sequence has a constant difference between each term.

General formula of an arithmetic sequence

[tex]\boxed{s_n=a+(n-1)d}[/tex]

where:

When expanded, the formulas for answer options a and b will both contain an n² term, so we can immediately discount them since an arithmetic sequence is linear.

Similarly, we can also discount option d since this formula includes an exponential term and is therefore not linear.

Therefore, the only valid answer is option c.

To confirm, rewrite the formula for c in the general form for an arithmetic sequence:

[tex]\begin{aligned}\implies s_n&=18+7(n-3)\\s_n&=18+7n-21\\s_n&=7n-3\\s_n&=7n-7+4\\s_n&=7(n-1)+4\\s_n&=4+(n-1)7\end{aligned}[/tex]

Therefore, formula that defines an arithmetic sequence is:

[tex]\boxed{s_n=18+7(n-3)}[/tex]

Answer: The amount an individual is required to pay in taxes is known as alternative minimum tax (AMT).

Step-by-step explanation:

Define Tax :

An amount of money that a government requires people to pay according to their income, the value of their property, etc., and that is used to pay for the things done by the government.

Some important Direct taxes include:

So,

People who have benefited greatly from tax breaks due to their high economic income are subject to the alternative minimum tax.

This tax acts as a corrective measure to ensure that person pays the least amount of tax possible.

The excess of a purported minimal tax above a regular tax is known as an alternative minimum tax. The income of a person, deductions, and exemptions are taken into account while determining the alleged minimum tax, and then the alternative minimum tax rate is applied.

It is then compared to the standard tax after receiving the purported minimum tax. The person is subject to alternative minimum tax if it is higher than the ordinary tax.

The alternative minimum tax may apply to taxpayers who have a lot of itemized deductions and tax preference items (AMT).

Therefore,  

The amount an individual is required to pay in taxes is known as alternative minimum tax (AMT).

Starting with the volume of a cube with side length [tex]x[/tex],

differentiate both sides with respect to time [tex]t[/tex]. By the chain rule,

[tex]\dfrac{dV}{dt} = 3x^2 \dfrac{dx}{dt}[/tex]

We're given that [tex]\frac{dx}{dt} = 2\frac{\rm in}{\rm min}[/tex].

39. At the moment [tex]x=8\,\rm in[/tex], solve for [tex]\frac{dV}{dt}[/tex].

[tex]\dfrac{dV}{dt} = 3 (8\,\mathrm{in})^2 \left(2\dfrac{\rm in}{\rm min}\right) = 384 \dfrac{\rm in^3}{\rm min}[/tex]

[tex]55\,\mathrm{in}^3 = x^3 \implies x = 55^{1/3} \,\rm in[/tex]

[tex]\dfrac{dV}{dt} = 3 \left(55^{1/3} \,\mathrm{in}\right)^2 \left(2\dfrac{\rm in}{\rm min}\right) = 6\cdot55^{2/3}\dfrac{\rm in^3}{\rm min}[/tex]

we get the same result if we multiply an number by 3 or if we multiply the numbers by 5 and then add 2.

Given that

To find

So, according to the question

we have,

Let's assume that number is x,

So, from question we can say that

                             = (3 × x) + 2

                   result = 3x + 2

and

                             = (5 × x) + 2

                   result = 5x + 2

Now, from question we know that the results are same

So,

                  3x+ 2  = 5x+ 2    

Now, simplify this        

                   5x - 3x = 2 - 2  

                          2x = 0

The probability the first roll is a 2 and the second roll is an odd number is 1/12

When we are unsure of the outcomes or simply want to know how probable something is to happen, we talk about probabilities. A random event is mathematically represented by probability. The collection of all potential outcomes is the sample space S for a probability model.

When we roll a dice there are 6 possible outcomes S={1, 2, 3, 4, 5, 6}.

The probability of showing a 5 is

Probability of showing 2 = 1/6

And the probability of showing an odd number is

Probability of showing an odd number = 3/6

Rolls are independent of one another, so there is a chance that the first roll will show a 5 and the second roll will reveal an even number.

( Probability of showing 2) ( Probability of showing an odd number) = 1/6 × 3/6 = 1/12.

Answer: 11

Step-by-step explanation:

If you use 0 dimes, you can use 11 nickels.

If you use 1 dime, you can use 9 nickels.

A chart develops:

0 11

1 9

2 7

3 5

4 3

5 1

So there are 6 ways to make 55 cents with nickels and dimes alone.

Now for the situation with 1 quarter:

We can have 0 dimes and 6 nickels.

We can have 1 dime and 4 nickels.

A chart follows:

0 6

1 4

2 2

3 0

So there are 4 ways to make change with nickels and dimes and 1 quarter.

Finally, if we use 2 quarters, we have 5 cents left over which must be a nickel adding 1 more way.

The trigonometric functions is y = 5/12.

The trigonometric functions sine, cosine, tangent, cosecant, secant, and cotangent really execute the opposite operation, which is what the inverse trigonometric functions do. We are aware that the right angle triangle is particularly amenable to trig functions. When two sides of a right triangle's measure are known, these six crucial functions are employed to determine the angle's measurement.

The convention symbol uses arc-prefixes such as arcsin(x), arccos(x), arctan(x), arccsc(x), arcsec(x), and arccot to denote the inverse trigonometric function (x).

arc sin(x) = arc tan (x/√1-x^2), x ∈ (0,1)

let,

y = tan (arc sin(5/13)) _____(1)

y = tan (arc tan ( 5/13/√1-(5/13)^2))

y = tan ( arc tan ( 5/ √13^2 - 5^2))

y = tan (arc tan (5/12))
