Now we can use the process of elimination to determine the smallest integer greater than the square root of 148.
15 is obviously too far to be the smallest integer greater than the square root of 148, so that is not the correct answer.
14 is pretty close to 12.1655250606, but we have three other options that are even closer so that cannot be the correct answer.
11 is also incredibly close to our square root, but there are two other options that are even closer. Therefore 11 will not be our answer.
Now that we have eliminated all other options but two of them, we have made it easy to determine which is correct.
12 is closer to 12.1655250606 than the number 13, so this would be the correct answer if the question was asking for the smallest integer of the square root of 148. But it is not.
The question asks for the smallest integer GREATER THAN the square root of 148. Therefore the correct answer to this question is 13.
QUICK ANSWER:
The smallest integer greater than the square root of 148 is 13.
For this case, you must use the given expression, taking into account that: n = number of days. We have then that for day 21, n = 21. Substituting we have: a21 = 100 + (21-1) * 4 a21 = 180 Answer: she sprints 180 yards on day 21
