A. 40
B.45
C. 35
D. 30

Answer 1

35 I just took the quiz

Explanation:

Answer 2

C. 35

EXPLANATION

The given expression is:

`15 - 35 - (85)/(n) + 55 + (75)/(2n) + \frac{15}{2 {n}^(2) }`

As

`n \to \: \infty`

`(k)/(n) \to0`

where k is a constant.

This implies that,

`15 - 35 - (85)/(n) + 55 + (75)/(2n) + \frac{15}{2 {n}^(2) } = 15 - 35 - 0 + 55 + 0+ 0 =35`

The correct answer is C
