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

Answer:
Step-by-step explanation:
we know that
The y-intercept is the value of y when the value of x is equal to zero
<em>Verify each case</em>
case 1) we have
so
For x=0
therefore
The function has a y-intercept of (0,5)
case 2) we have
so
For x=0
therefore
The function does not have a y-intercept of (0,5)
case 3) we have
so
For x=0
therefore
The function does not have a y-intercept of (0,5)
case 4) we have
so
For x=0
therefore
The function has a y-intercept of (0,5)
case 5) we have
so
For x=0
therefore
The function does not have a y-intercept of (0,5)
