S^2 + 9s - 142 > 2000
s^2 + 9s - 142 - 2000 > 0
s^2 + 9s - 2142 > 0
(s-42)(s+51) > 0

s - 42 > 0
s > 42

Answer: s>42

Step-by-step explanation:

Given: The profit, p, made by the company is modeled by the function

s^2+9s-142.

According to the question, we have

s^2 + 9s - 142 > 2000\\\Rightarrow s^2 + 9s - 142 - 2000 > 0\\\Rightarrow s^2 + 9s - 2142 > 0\\\Rightarrow (s-42)(s+51) > 0\\\Rightarrow s>42\ \ ,\ s>-51

But s>-51 is not possible.

Hence, s>42 is the answer.

8/11 is the answer

I use this trick: When tryig to find repeating numbers divide by 11 or 9

When dividing by 9 the numerator will be the first number in the decimal

When dividing by 11 the numerator will be one more than the first number in the decimal
