Ok,
f(0.35)= 7f/20
f(-5.2)=-26f/5
f(10)= 10f
f(-0.5)= -f/2
as for the last question I am not quite sure, sorry....hope I helped a little :)
Answer:
The length of the hypotenuse is 26 inches
Step-by-step explanation:
The leg(brace) attached to the wall is 10 inches
Perpendicular = 10 inches
Your surfboard sits on a leg that is 24 inches.
Base = 24 inches
Formula : 


Hypotenuse = 26
Hence the length of the hypotenuse is 26 inches
