H = {(2, 5), (3,5), (4, 5), (5,5), (6,5)} Is H a function and why? No, there is a limited number of ordered pairs in this list.

Yes, no two ordered pairs in this list has the same first element.

No, each set of ordered pairs in this list has the same second element.

Yes, there is more than one ordered pair in this list.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
