(a) The resultant displacement A + B has a magnitude of 4.56 km. What is the magnitude of B? __________ km
What is the direction of A + B relative to due south? _______degrees (east of south)
(b) Suppose that A - B had a magnitude of 4.56 km What then would be the magnitude of B and what is the direction of A - B relative to due south?
_________ km
direction of A - B relative to due south
__________ degrees (west of south)

On a safari, a team of naturalists sets out toward a research station located 5.2 km away in a direction 42 degrees north of east. After traveling in a straight line for 2.5 km, they stop and discover that they have been traveling 29 degrees north of east, because their guide misread his compass. What are the magnitude and direction (relative to due east) of the displacement vector now required to bring the team to the research station?
magnitude ________ km
direction ________ degrees (north of due east)

Let n belongs to N and given a belongs to Z, let a* represent the congruence class of a modulo n. if a1* = a2* and b1* = b2* for integers a1,a2,b1,b2, then prove that (a1b1)* = (a2b2)*.

if p is a prime, explain why all elements in Z / pZ have multiplicative inverses

I have tried but cant go anywhere with it. need help. thank you.

You have 10 bags. Each bag has 10 coins. One of the ten bags is full of counterfit coins, but you don't know which bag. Real coins weigh 10 grams and counterfit coins weigh 9 grams. If you can use a scale only one time how can you determine which bag has the counterfit coins? You may only weigh it one time, meaning you can only read the scale once. You can't lift up the bags and feel which is heavier either. There is a logical solution.

First to get it right gets the 10 points!

If you get stumped then just email me and i'll send you the answer.

Have fun!
