How is a the ball served in 4-square. What is a “fault” when serving? Use a minimum of 5 sentences to describe.

Faults are allowed only once for both the server or the receiver. The server can fault if the serve into one square is too high, too low, too fast, or otherwise unreturnable by the receiver. The receiver may send the ball back to be served again.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
