Answer: 
Step-by-step explanation:



In this question, the profit of the restaurant after t months is given by a polynomial function. To find when it begins to show a profit, we find the numerical values of the function for t, and it shows a profit when 
Profit after t months:

0 months:
This is P(0). So

1 month:
This is P(1). So

2 months:
This is P(2). So

3 months:
This is P(3). So

4 months:
This is P(4). So

5 months:
This is P(5). So

6 months:
This is P(6). So

7 months:
This is `P(7). So

After 7 months it shows profit, so it starts showing profit on the 6th month, and thus, the correct answer is given by option D.

(−2h+9)(9h−2)
-18h^2 + 4h + 81h - 18
Answer: -18h^2 + 85h - 18
This is how it would work to find answer
You divide 225 by 45 and the answer you would get is 5 so
It will take 5h for the train to travel
