1. A golfer takes two putts to get his ball into the hole once he is on the green. The first putt displaces the ball 6.50 m east, the second 3.00 m south. What displacement would have been needed to get the ball into the hole on the first putt?

I got 7.159 m as my answer.

2. A person walks 25.0° north of east for 2.80 km. How far would the person walk due north and due east to arrive at the same location?

I got 1.183 km for North and 2.538 km for East.

3. A girl delivering newspapers covers her route by traveling 10.00 blocks west, 4.00 blocks north, and then 5.00 blocks east.

(a) What is her resultant displacement?

Im not entirely sure about this, I believe resultant displacement is the hypotenuse? If it is I got 6.403 blocks for my answer.

(b) What is the total distance she travels?

I got 19 blocks for this.

Hey i am trying to do (1-a^3)/(1-a^2). I have completed the square on the bottom and (a-1) is a factor on the top. The answers should be (1+a+a^2)/(1+a) but i keep getting a remainder dividing a-1 into 1-a^3. Any help appreciated thanks.
