To find the coefficients A and B in the inverse Laplace transform of F(s), we need to use partial fraction decomposition and the properties of Laplace transforms. Here's how we do it:
First, we factor the denominator of F(s) as (s-1)(s+6). Then we write F(s) as a sum of two fractions with unknown coefficients A and B:
[tex]F(s) = \frac{7s}{(s-1)(s+6)} = \frac{A}{s-1} +\frac{B}{s+6}[/tex]
To find A, we multiply both sides by (s-1) and then take the inverse Laplace transform:
[tex]L^{-1} [F(s)] = L^{-1}[\frac{A}{s-1} ] +L^{-1}[\frac{B}{s+6} ][/tex]
[tex]f(t) = A e^t + B e^{-6t}[/tex]
Since we know that the inverse Laplace transform of F(s) has the form of f(t) = A e^t + B e^(-6t), we can use this expression to solve for A and B. We just need to evaluate f(t) at two different values of t and then solve the resulting system of equations.
Let's start with t=0:
[tex]f(0) = A e^0 + B e^{0} = A + B[/tex]
Now let's take the derivative of f(t) and evaluate it at t=0:
[tex]f'(t) = A e^{t} - 6B e^{-6t}[/tex]
f'(0) = A - 6B
We can now solve the system of equations:
A + B = f(0) = 0 (since F(s) is proper, i.e., has no DC component)
A - 6B = f'(0) = 7
Solving for A and B, we get:
A = 21/7 = 3
B = -21/7 = -3
Therefore, the coefficients in the inverse Laplace transform of F(s) are:
A = 3
B = -3

There were 24 people invited to a pizza party. One-fourth of the people wanted sausage and olives. Three-fourths
wanted plain cheese. How many plain pizzas should Sam order?
18,16,14?
Answer:
the number of plain pizza does sam order is 18
Step-by-step explanation:
The computation of the number of plain pizza does sam order is shown below:
= Total people invited to a pizza party × plain cheese
= 24 × 3 ÷ 4
= 18
Hence, the number of plain pizza does sam order is 18

6.) Resuelve: 6(X + 8) - 30 + 7 = 49
Answer:
x=4
Step-by-step explanation:
6(x+8)-30+7=49
6x+48-30+7=49
6x=49-48+30-7
6x=1+23
6x=24
x=[tex]\frac{24}{6}[/tex]
x=4
Step-by-step explanation:
Para resolver esto yo use una app llamada m a t h w a y
(sin los espacios) esta puede estar en varios idiomas, aunque esto se modifica segun el idioma en donde la uses.
6(x+8) -30+7 = 49 1. Simplifica 6(x+8) -30+7
6x+25 = 49 2. Mueve todos los términos que no
contengan x al lado derecho de la ecuación
6x = 24 (25 pasa restando por lo cual sería, 49-25
que es igual a 24.)

Can 4(x+2)=10 equal 0
Answer:
x = 0.5
Step-by-step explanation:
The given expression is :
4(x+2) = 10
Using commutative property at LHS.
4x+8 = 10
Subtract 8 from both sides.
4x+8-8 = 10-8
4x = 2
x = (1/2) = 0.5
So, the value of x is equal to 0.5 instead of 0. Hence, the given expression cannot be equal to 0.

Solve and graph the inequality.
7n - 1 > 76
Answer:
n>11
Step-by-step explanation:
I don't know how to graph this answer, sorry!
The solution of the inequality 7n - 1 > 76 gives n < 11 along with the graph.
Given Inequality:
7n - 1 > 76
To solve the inequality add 1 on both side of inequality as
7n - 1 + 1 > 76 + 1
7n > 77
Now, divide the inequality by 7 as
7n/ 7 > 77/ 7
n > 11.
Therefore, the solution is n > 11.

Answer:

Step-by-step explanation:
Rule: multiply by 2 Pattern: 3,6,12,24,48 Observation: Observation = something similar about the numbers
Step-by-step explanation:
This numerical sequence corresponds to a geometric progression, which occurs when there is a multiplication of the sequence numbers for a common reason whose result will always be the successor number of the numerical sequence.
Like for example:
3,6,12,24,48
The common reason for the geometric progression is the number 2, so the first term of the sequence multiplied by 2 will be equal to the second term of the sequence and so on:
3x2 = 6
6x2 = 12
12x2 = 24
24x2 = 48
It is necessary to emphasize that the ratio of a geometric progression will always be constant and will always be a number other than zero.
