At Rome in 1987 Candian Ben Johnson reduced the world record time for 100m, 9.93 seconds, by 1%. What was the new world record (correct to 2 decimal places).

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.

Can anyone explain to me how to do this? anything will .

In the triangle rst, rs = 65 and st = 60. which equation could be used to find the value of angle s?
