B because the line over the 28 means that it’s repeating and a repeating decimal = rational number example : 27.67777777 is a rational number because it’s repeating and an irrational number would be 27.6719473637

What is the sum of the first 37 terms of the arithmetic sequence?

lidiya [134]

Answer:

The sum of the first 37 terms of the arithmetic sequence is 2997.

Step-by-step explanation:

Arithmetic sequence concepts:

The general rule of an arithmetic sequence is the following:

$a_{n+1} = a_{n} + d$

In which d is the common diference between each term.

We can expand the general equation to find the nth term from the first, by the following equation:

$a_{n} = a_{1} + (n-1)*d$

The sum of the first n terms of an arithmetic sequence is given by:

$S_{n} = \frac{n(a_{1} + a_{n})}{2}$

In this question:

$a_{1} = -27, d = -21 - (-27) = -15 - (-21) = ... = 6$

We want the sum of the first 37 terms, so we have to find $a_{37}$

$a_{n} = a_{1} + (n-1)*d$

$a_{37} = a_{1} + (36)*d$

$a_{37} = -27 + 36*6$

$a_{37} = 189$

Then

$S_{37} = \frac{37(-27 + 189)}{2} = 2997$

The sum of the first 37 terms of the arithmetic sequence is 2997.

Someone please help me with this question

Sauron [17]

Answer:

Step-by-step explanation:

Again, anything to the 0th power is equal to 1.

The 0th power is attached to the b, so this means that b = 1. Multiply 9 and (1) together to get 9.

Now you can subtract 9 from 12 to get 3 as your final answer.

PLEASE HELP QUICK!!!! What is the degree of 7x^6 - 6x^5 + 2x^3 + x - 8? A. 8 B. 7 C. 5 D. 6

antiseptic1488 [7]

For determining the correct degree of a polynomial, you need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.

7x^6 has largest degree of the given polynomial, so your answer is D.6
