Answer:
Inverse Laplace of
will be 
Step-by-step explanation:
We have to find the inverse Laplace transform of 
We know that of
is 
As in H(s) there is square of 
So i inverse Laplace there will be multiplication of t
So the inverse Laplace of
will be 

Answer:
Step-by-step explanation:
Hello!
(5x+4) /( (x-4)( x+2))
(5x+4)/ (x² +2x -4x -8)=
(5x+4) /( x²-2x -8)
Use Pythagorean Theorem:
a² + b² = c²
"a" is one side of the right triangle.
Its length is: radius of larger circle minus radius of smaller circle: (11 - 3 = 8)
The distance between the center of the circles creates the hypotenuse (17)
8² + b² = 17²
b² = 225
b = 15
Answer: the length of the common external tangent is 15.
