Find the inverse Laplace transform, f(t), of the function:<br><br> F(s) = 7/s^2 + 5s + 24

BARSIC [14]

Answer:

$y(t)=\frac{14}{\sqrt{71}}e^{-\frac{5}{2}t}sin\frac{\sqrt{71}}{2}t$

Step-by-step explanation:

We are given that a function

F(s)= $\frac{7}{s^2+5s+24}$

We have to find the inverse transform of the function

F(s)= $\frac{7}{s^2+2\cdot \frac{5}{2}s+\frac{25}{4}-\frac{25}{4}+24}$

F(s)= $\frac{7}{(s+\frac{5}{2})^2+(\frac{\sqrt{71}}{2})^2}$

We know that laplace transform of sinhat

L(sinat)= $\frac{a}{s^2+a^2}$

L $(e^{at}sinbt)=\frac{b}{(s-a)^2+b^2}$

Using this formula we get

$y(t)=\frac{7}{\frac{\sqrt{71}}{2}}\times e^{-\frac{5}{2}t}sin\frac{\sqrt{71}}{2}t$

$y(t)=\frac{14}{\sqrt{71}}e^{-\frac{5}{2}t}sin\frac{\sqrt{71}}{2}t$

During a certain day, a worker did 77 parts. He usually does 55 parts per day. What was the percent by which he increased the us

ANTONII [103]

So, he usually does 55 only, but this one day he did 77, 77 - 55 is 22, so he did 22 more this one day.

if we take 55 to be the 100%, what is 22 off of it in percentage anyway?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
55&100\\
22&p
\end{array}\implies \cfrac{55}{22}=\cfrac{100}{p}\implies p=\cfrac{22\cdot 100}{55}$

Mmath help pls, will reward!! O_O

Setler79 [48]

Answer:

x = -4, y = 8.

Step-by-step explanation:

Question 16.

8x + y = -24 ........(A)

-3x - 2y = -4 ........(B)

Multiply (A) by 2:

16x + 2y = -48 Adding this to equation (B):

13x = -52

x = -4

Substituting this value of x in Equation (A):

8(-4) + y = -24

y = -24 + 32 = 8.

The product of two consecutive negative integers is 600. What is the value of the lesser integer?

Aloiza [94]

Answer:

-24

Step-by-step explanation:

The prime factors of 600 2*2*2*3*5*52*2*2*3 = 24 and 5*5 = 25 so the 2 negative integers is -24 and -25 and lower integer is -25

But...

The negative integers can also be positive as 24*25 = 600

Edit: It says negative so it has to be -24

So... the answer is -24
