Find a formula for the general term of the sequence 5 3 , − 6 9 , 7 27 , − 8 81 , 9 243 , assuming that the pattern of the first
Mkey [24]

Answer:

The formula to the sequence

5/3, -6/9, 7/27, -8/81, 9/243, ...

is

(-1)^n. (4 + n). 3^(-n)

For n = 1, 2, 3, ...

Step-by-step explanation:

The sequence is

5/3, - 6/9, 7/27, - 8/81, 9/243, ...

We notice the following

- That the numbers are alternating between - and +

- That the numerator of a number is one greater than the numerator of the preceding number. The first number being 5.

- That the denominator of a number is 3 raised to the power of (2 minus the position of the number)

Using these observations, we can write a formula for the sequence.

(-1)^n for n = 1, 2, 3, ... takes care of the alternation between + and -

(4 + n) for n = 1, 2, 3, ... takes care of the numerators 5, 6, 7, 8, ...

3^(-n) for n = 1, 2, 3, ... takes care of the denominators 3, 9, 27, 81, 243, ...

Combining these, we have the formula to be

(-1)^n. (4 + n). 3^(-n)

For n = 1, 2, 3, ...

What is the difference of the polynomials? (â€""2x3y2 4x2y3 â€"" 3xy4) â€"" (6x4y â€"" 5x2y3 â€"" y5) â€""6x4y
zlopas [31]

Polynomial-An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable. The difference between the given polynomials is

=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5

Given-

We have given two function of variable <em>x </em>and <em>y</em>

(-2x^3y^2 + 4x^2y^3-3xy^4)

(6x^4y-5x^2y^3-y^5)

<h3>Polynomial</h3>

An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable.

Now we have to subtract the two equations to find the difference,

(-2x^3y^2 + 4x^2y^3-3xy^4)-(6x^4y-5x^2y^3-y^5)

Multiply the sign into the bracket to open the bracket and further solution,

=-2x^3y^2 + 4x^2y^3-3xy^4-6x^4y+5x^2y^3+y^5

Arrange the similar terms in the same groups,

=-2x^3y^2 + (4x^2y^3+5x^2y)-3xy^4-6x^4y+y^5=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5

Hence, the difference between the given polynomials is=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5

which transformation of the function f(x) is the rigid motion: 2f(x)+3, f(x/2)+1, 2f(x/2), or f(x-1/2)+3
Katarina [22]
Answer is choice D. The other choices involve dilations, or scalings, which basically make the graph taller or flatter depending on what the scale factor is. In the case of f(x-1/2)+3, we shift f(x) to the right 1/2 a unit and up 3.
