Answer:
FA = 25.87
Step-by-step explanation:
Given: BD = 30 , DF = 5 , EF = 16
To find: FA
Rectangular box is a Cuboid.
Figure attached.
AB = FE = 16
So,
In ΔADB
using Pythagoras theorem,
Again using Pythagoras theorem in Δ ADF we get
Therefore, FA = 25.87
To express a function of the form 
in vertex form 
where (h,k) is the vertex of the parabola, we need to find the vertex first.
To find the vertex we are going to use the vertex formula:
, and 
will be the function evaluated at 
.
We can infer from our function that
and 
. So lets find :
Now that we have, we can evaluate the function at 1 to find :
We have the vertex (1,3) of our parabola, so we can use its vertex form:
We can conclude that the vertex for of our parabola is <span>f(x) = (x + 1)2 + 3.</span>
