Suppose we have a set of sports teams in a league L, and a set of games G among those teams. Each game has a home team and a visiting team, who are two different teams in the league. We have predicates H(g, t) meaning "team t was the home team in game g" and V (g, t) meaning "team t was the visiting team in game g". Required:
Consider the predicate P(s, t) meaning "team s played a game against team t". Can you express this predicate in terms of the predicates H and V, along with boolean operators?

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.

Effective character encoding requires standardized code. compatible browsers. common languages. identical operating systems.

1. which of the following statements are true about routers and routing on the internet. choose two answers. a. protocols ensure that a single path between two computers is established before sending packets over it. b. routers are hierarchical and the "root" router is responsible for communicating to sub-routers the best paths for them to route internet traffic. c. a packet traveling between two computers on the internet may be rerouted many times along the way or even lost or "dropped". d. routers act independently and route packets as they see fit.
