The given sequence : {1, 3, 5, 7, 9, … }

The term of the sequence are consecutive odd numbers .

Let n be the number of terms.

We make the following table ,

n                a_n

1                   2(1)-1=1

2                   2(2)-1=3

3                   2(3)-1=5

4                   2(4)-1=7

5                   2(5)-1=9

Therefore, the function for the given sequence : f(n)=2n-1

PLS ANSWER IT I just need the answer
aalyn [17]

The y-intercept is (0,2)

  • you can find the y-intercept by finding the value of y when x = 0

The slope is -5/2.

  • you can find the slope by using the equation below and any two points on the line, such as (0,2) and (2,-3)

           \frac{y2-y1}{x2-x1}=\frac{-3-2}{2-0}  =\frac{-5}{2}

               

Hope that helps!

Answer:

1 3/4

Step-by-step explanation:

3 1/2 boxes of tomatoes currently. uses 1 3/4, taking it away basically.

3 1/2 - 1 3/4

3 2/4 - 1 3/4 ;; i did this with finding a common denominator for it to be easier for me to solve.

3 - 1 = 2

2/4 - 3/4 = -1/4

2 + -1/4 = 1 3/4

correct me if wrong.

Mr. Parker's class has 7 feet of white paper and 8 feet of yellow paper to make posters they will cut the paper into 2-foot post
Viktor [21]

Answer:

In total, they will be able to cut 7 posters.

Step-by-step explanation:

Mr. Parker's class has 7 feet of white paper and 8 feet of yellow paper to make posters.

If they cut the paper into 2-foot posters, then from 8 feet of yellow paper they will make \frac{8}{2} = 4 posters.

Now, from the 7 feet white paper if they cut 2-foot posters then they will make 3 posters maximum as \frac{7}{2} = 3.5.

Therefore, in total, they will be able to cut (4 + 3) = 7 posters. (Answer)

Please Help!!!

B and C are absurd; if a series converges, it must have a sum, but if a series diverges, it cannot have a sum.

Now, notice that

\dfrac12+\dfrac29+\dfrac4{27}+\dfrac8{81}+\cdots=\dfrac12+\dfrac{2^{2-1}}{3^2}+\dfrac{2^{3-1}}{3^3}+\dfrac{2^{4-1}}{3^4}+\cdots

That is, we can write the sum more compactly as

\dfrac12+\dfrac12\displaystyle\sum_{n=1}^\infty\left(\frac23\right)^n

The series is geometric with common ratio \dfrac23, so the series converges (and thereby has a sum), so the answer is D.
