An arithmetic sequence is represented by the explicit formula A(n) = 8 - 6(n - 1) What is the recursive formula? Group of answer choices

Answers

Answer:

A(1) = -4A(n) = A(n - 1) - 6

Step-by-step explanation:

GivenAP with the explicit formula A(n) = 8 - 6(n - 1)To find Recursive formulaSolution

Recursive formula is the formula A(n) = A(n - 1) + d

Based on the explicit formula we have:

A(n) = 8 - 6(n - 1) = 8 - 6n + 6 = 2 - 6nA(n - 1) = 2 - 6( n - 1) = 2 - 6n + 6 = 8 - 6n

The common difference is:

d  = A(n) - A(n - 1) = 2 - 6n - (8 - 6n) = 2 - 6n - 8 + 6n = - 6

The first term is:

A(1) = 2 - 6(1) = 2 - 6 = -4

So the recursive formula is:

A(1) = -4A(n) = A(n - 1) - 6

You are eating a slice of pizza that has 391 calories in it. Each time you dip the pizza into ranch dressing, though, you add 7 calories to the total. If your meal wound up being 454 calories in total, how many times did you dip the pizza into ranch dressing? I don't get it

Answers

Answer:I think it is about 55 times

Step-by-step explanation:

Answer:

9 times

Step-by-step explanation:

The pizza has 391 calories in it, and everytime you dip it into ranch, you add 7 calories to the 391.

454(calories in total) - 391(calories in the pizza)= 63

63 ÷ 7(calories everytime you dip into ranch) = 9

Evaluate (27)-2

Express your answer as a fraction in simplest form.
The solution is

Answers

Note: The expression you have written sounds a little unclear, but I am assuming your expression is (27)-2-2/3.

So, I am solving the question based on assuming the expression as (27)-2-2/3, which would still clear your concept.

Answer:

The expression in the simplest form is:

[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(27\right)-2-\frac{2}{3}[/tex]

simplifying the expression in the simplest form

[tex]\left(27\right)-2-\frac{2}{3}[/tex]

[tex]=25-\frac{2}{3}[/tex]

[tex]=\frac{25\cdot \:3-2}{3}[/tex]

[tex]=\frac{73}{3}[/tex]

Thus, the expression in the simplest form is:

[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]

Answers

Answer:

CD = 7

Step-by-step explanation:

Given that the triangles are congruent, then corresponding sides are congruent, that is

CD = AB , substitute values

3y + 1 = 15 - 4y ( add 4y to both sides )

7y + 1 = 15 ( subtract 1 from both sides )

7y = 14 ( divide both sides by 7 )

y = 2

Thus

CD = 3y + 1 = 3(2) + 1 = 6 + 1 = 7

(6,5), 7x-3y=5 find the equation of the line that contains the given point and is parallel to the line. write the equation in slope intercept form

Answers

Answer:

y = (7/3)x - 9

Step-by-step explanation:

1. Convert given equation to y=mx+b form --> y = (7/3)x - 5/3

2. Equation of new line --> y = (7/3)x + b

Note: 7/3 is the slope and for lines to be parallel they need the same slope so both equations have 7/3.

3. Plug in given values --> 5 = (7/3)(6) + b

4. Solve for b --> b = 5 - 14    b = -9

5. New line --> y = (7/3)x - 9

5. What is the next term of the sequence -3, 6, -12, 24,... , and what it's arithmetic sequence?

Answers

Answer:

a(5)=-48

Step-by-step explanation:

I think u r confused

this sequence is geometric not arithmetic

HOw we know that ??

when we get a common difference  that must Be equal  

d=6+3=9  not equal to  d=-12-6=-18

So it is not arithmetic

but when we get the common ratio that also must be equal

r=6/-3=-12/6=24/-12=-2   equal

So it is geometric

By using this equation:

a(n)=a*r^(n-1)

and we have a=-3 , r=-2

Then       a(n)=-3*(-2)^(n-1)

To get the next term:

a(5)=-3*(-2)^(5-1)

a(5)=-3*(-2)^(4)

a(5)=-3*16=-48
