Inverse laplace transform of H(s) = 1/(s+4)^2
ziro4ka [17]

Answer:

Inverse Laplace of \frac{1}{(S+4)^2} will be te^{-4t}

Step-by-step explanation:

We have to find the inverse Laplace transform of H(S)=\frac{1}{(S+4)^2}

We know that of \frac{1}{s+4} is e^{-4t}

As in H(s) there is square of s+4

So i inverse Laplace there will be multiplication of t

So the inverse Laplace of \frac{1}{(s+4)^2}  will be te^{-4t}

L^{-1}\frac{1}{(S+4)^2}=te^{-4t}

What is an expression for the area of the shaded region? Simplify your answer.
Reptile [31]

Answer:

if it is put into a equation this would be it

2(x^2+6x+9) - (1.57)(x^2+6x+9)

Step-by-step explanation:

(x+3)(2x+6) - 1/2(3.14)(x+3)(x+3)

(2x^2+6x+6x+18) - 1/2(3.14)(x^2+3x+3x+9)

(2x^2+12x+18) - 1/2(3.14)(x^2+6x+9)

2(x^2+6x+9) - (1.57)(x^2+6x+9)

2(x^2+6x+9) is the rectangle at the bottom

(1.57)(x^2+6x+9) is the semicircle that is taking out of the shaded area

Zero and negative exponentswrite in simplest for without zero or negative exponents- 17 ⁰
Valentin [98]
-17^0=(-17)^0=1\begin{gathered} (-2)^2\times(-2)^{-5}=(-2)^{2-5} \\ =(-2)^{-3} \\ =\frac{1}{(-2)^3} \\ =\frac{1}{-8} \end{gathered}

Thus, the final answers are 1 and -1/8.
