<PRE><B>Question 138838</B>
The endpoints of segment FG have coordinates F(1/2a,-b)and G(a,1/4b). What is the expression for the length of the segment?
----------------------------------
distance = sqrt[(change in x)^2 + (change in y)^2]

distance = sqrt[(a -(1/2)a)^2 + ((1/4)b + b)^2]

d = sqrt[(1/4)a^2 + (25/16)b^2]

d = sqrt[(1/16)[4a^2 + 25b^2]]

d = (1/4)sqrt[4a^2 + 25b^2]
