Use | S − S N | ≤ b N + 1 to find the smallest value of N such that S N approximates the value of the sum S to within an error of at most 10 − 4 . S = [infinity] ∑ n = 1 ( − 1 ) n + 1 n ( n + 4 ) ( n + 5 )

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
