The answer was 3. Reply

 06-09-2012, 01:43 PM #35 Junior Member   Join Date: Apr 2012 Posts: 184 Ok, what was the answer you were trying to find for the nail one? The distance needed to double the force with an original distance of 12? Reply
 06-09-2012, 01:43 PM #36 Junior Member   Join Date: Jun 2012 Posts: 65 the taxi one was 8. It said that the taxi was 7 miles east and 3 miles south giving a coordinate at (7, -3) They then gave you unnecessary info about the route to get to the headquarters. you had to do the distance from origin to 7, -3 which is 7.61577 and you round to 8 because it said closest Reply
 06-09-2012, 01:43 PM #37 Junior Member   Join Date: Mar 2012 Posts: 38 @ValkyrieXT I think it will be very favorable. On the June test, I think that there is a larger amount of uhh.. low scorers. Which would make the curve a bit more favorable. I am expecting -1 = 36 ; -2 = 35. Reply

 06-09-2012, 01:45 PM #39 Junior Member   Join Date: Mar 2012 Posts: 38 @hotelrwanda it asked for the distance to the HQ, so the information was necessary. Reply
 06-09-2012, 01:45 PM #40 Junior Member   Join Date: Apr 2012 Posts: 184 @mets I got A, I just plugged the answers back into the equation. Reply
 06-09-2012, 01:45 PM #41 Junior Member   Join Date: Apr 2012 Posts: 48 What was the one that had something to do with a+bi? Was the answer a-bi? Reply
 06-09-2012, 01:45 PM #42 Junior Member   Join Date: May 2012 Posts: 105 it was a= -2/5 and b = 20 or a was something else but i know b was 20. It was a VERY tricky problem. had me thinking like crazy Reply
 06-09-2012, 01:46 PM #43 Junior Member   Join Date: Jun 2012 Posts: 65 yea it said that the taxi was 7 miles east and 3 miles south so you could assume origin. Reply

 06-09-2012, 01:46 PM #45 Junior Member   Join Date: Jan 2012 Posts: 46 the question said the force was inversely proportional to the square of the distance, so the original force was 12, so the force was 1/144, so the answer was 6rad2 because the inverse square of 6rad is 1/72 Reply
