Approximate the sum of the convergent infinite series the least usingnumber of terms so that the error is less than .0001. What is the fewest number of terms needed and round your result to three decimal places and state maximum error.

Solution :

Error =

Error ≤ 0.0001

Now try, n ≥ 5

  =         (with error 0.0001)

  =

= 0.6065104

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
