Suppose that g = (v, e) is a directed graph. a vertex w ∈ v is reachable from a vertex v ∈ v if there is a directed path from v to w. the vertices v and w are mutually reachable if there are both a directed path from v to w and a directed path from w to v in g.

show that { (u, v) | u and v are mutually reachable in directed graph g = (v, e) } is an equivalence relation (i. e., reflexive, symmetric, and transitive).

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

step-by-step explanation:

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6

-lavira : )

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
