Given: F = {(0, 1), (2, 4), (4, 6), (6, 8)} and G = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)} (F + G) (2) =

Answer:
9
Step-by-step explanation:
(F+G)(2)
=F(2)+G(2)
Stop!
F(2) means what is y when x=2 looking at function F.
F(2)=4 since F has the ordered pair (2,4) which says when x=2, y=4.
G(2) means what is y when x=2 looking at function G.
G(2)=5 since G has the ordered pair (2,5) which says when x=2, y=5.
G(2)=5.
Continue!
(F+G)(2)
=F(2)+G(2)
=4+5
=9

Let the distance of two consecutive stones are x, x+1.
In ΔBCD, we have
tan60
o
=
