The thousandth's decimal mark is the third number behind the decimal point which in this case it would be 9. To round to the nearest thousandths you need to look at the number behind 9 which is 1. 1 is less than 5 so you wouldn't round to 10. The answer is .009!
Answer:
63
Step-by-step explanation:
Since the discriminant is positive, this means we have two distinct real solutions.
If a, b, and c are rational numbers, then a discriminant of D = 40 indicates the two solutions are not rational. We would need D to be a perfect square to get two rational solutions.
