Suppose f is a coordinate function for l=(line) AB such that f(A)=0 and f(B)>0. Prove that (ray) AB={P (is an element of) l such that f(P) >=0}

Hint: the definition of ray: the ray AB is the set of points = Segment AB union {P: A*B*P}

HELP PLEASE. This all has to do with Neutral Geometry if that helps any.

ok i need to use IG axioms.

If there exists a unique point p sch that p lies on both l and m, then l and m are distinct, non parallel lines.

Prove using Incidence geometry axioms. A full proof would be wonderful.

I'm still a little confused...

a point is randomly selected with a rectangle whose vertices are (0,0), (2,0), (2,3) and (0,3). What is the probability that the x-coordinate of the point is less than the y-coordinate?

Thank you!

THree horses run a race. How many different ways can the three finish if ties are allowed?

I used permutation of n^r so 3^3=27 different ways for them to finish. Just want to make sure this is correct?

Also, Which of the following numbers is a perfect square? ( I need to know to figure this out without a calculator and how to explain it)

329476 (i know this is the answer) 389372 964328 326047 and 724203

Three horses run a race. How many different ways can the three finish if ties are allowed?

I used permutations w/ repetition and got n^r n=3 r=3. so there are 27 different ways the three horses can finish... just want to make sure this is correct.

Thank you again for the help

(I tried posting a link to a picture but it wouldn't let me. For the most part its an equilateral triangle in a square. the triangle is slanted and is as large as possible. If you type equilateral triangle in a square into google search, its the first website and halfway down the website is the triangle/square picture.

a 2inch x 2inch square has an equilateral triangle inside. what are the sides of the triangle. Picture is identical to the one given to me.

Thank you all!

I need to show how the Rationals (R) and the complex numbers (C) are logically equivalent. or in turn lCl=lR^2l

Help would be amazing! thank you!
