What is the value of a if (2a +3) - (4a-8)= 7
mars1129 [50]
( 2a + 3 ) - ( 4a - 8 ) = 7
2a + 3 - 4a + 8 = 7
-2a + 11 = 7 
-2a = -4
a = -4 / -2
a = 2

(with steps please) Find the inverse Laplace transform, f(t), of the function: s/((s^2+9)*(s^2+16))
sveta [45]

Answer:

Step-by-step explanation:

Given is a Laplace transform of f(t) as

F(s) = \frac{s}{(s^2+9)(s^2+16)}

Let

\frac{s}{(s^2+9)(s^2+16)}=\frac{As+B}{(s^2+9)}+\frac{Cs+D}{(s^2+16)}

Solving we get \:s=s^3\left(A+C\right)+s^2\left(B+D\right)+s\left(16A+9C\right)+\left(16B+9D\right)

A+C=0:  B+D=0: 16A+9C=1 and 16B+9D=0

Solving B=0=D

A=\frac{1}{7} \\C=\frac{-1}{7}

Hence we have

f(t) = inverse Laplace of

\frac{1}{7}[ \frac{s}{(s^2+9)}-\frac{s}{(s^2+16)}]

=\frac{1}{7} (cos 3t-cos 4t)
