Inverse laplace of L^-1 {5s/s^2 + 3s - 4}​
Salsk061 [2.6K]

Answer:

e^t+e^{-4t}

Step-by-step explanation:

We have to simplify the original function using partial fraction, hence:

\frac{5s}{s^2+3s-4} =\frac{5s}{(s-1)(s+4)}\\\\=\frac{A}{s-1}+\frac{B}{s+4}\\\\Therefore:\\\\\frac{A(s+4)+B(s-1)}{(s-1)(s+4)}=\frac{5s}{(s-1)(s+4)}\\\\Eliminating\ the \ denominator:\\\\A(s+4)+B(s-1)=5s\\\\substitute\ s=1:\\\\A(1+4)+B(1-1)=5(1)\\\\5A=5\\\\A=1\\\\tsubstitute\ s=-4:\\\\A(-4+4)+B(-4-1)=5(-4)\\\\-5B=-20\\\\B=4\\\\Therefore\ substituting\ A\ and\ B\ gives:\\\\\frac{5s}{s^2+3s-4}=\frac{1}{s-1}+ \frac{4}{s+4}\\\\

From\ Laplace\ inverse:\\\\But\ L^{-1}[\frac{1}{s-a} ]=e^{at}\\\\Hence:\\\\L^{-1} [\frac{5s}{s^2+3s-4}]=L^{-1}[\frac{1}{s-1} ]+L^{-1}[\frac{4}{s+4} ]=e^{t}+4e^{-4t}\\\\L^{-1} [\frac{5s}{s^2+3s-4}]=e^{t}+4e^{-4t}

Given f(x)=3x2−5x−2 .<br><br> What is the value of f(−23) ?
Sonja [21]

f(x) =  {3x}^{2}  - 5x - 2 \\ f( - 23) = ... \\ f( - 23) \: means \: x =  - 23 \\ so \: f( - 23) =  {3( - 23)}^{2}  - 5( - 23) - 2 \\  = 3(529)  + 115 - 2 \\  = 1700

Inez has to pay 4 percent in closing costs and 16 percent for the down payment on a purchase of $225,500 with an ARM. Over the l
vivado [14]

Answer:

A. $307,172.72

Step-by-step explanation:

Inez has to pay 4 percent in closing costs and 16 percent for the down payment on a purchase of $225,500 with an ARM.

4% + 16% = 20%

lnez has to pay 20% of $225,500

= 225,500*20/100

= 225,500*0.2

= $45100

lnez has to pay $45100.

Over the life of the loan, lnez will pay $262,072.72

Now we have to add down payment, closing cost and the payment over the life of the loan.

$45100 + $262,072.72

= $307,172.72

Answer: A. $307,172.72

Thank you.

Brainliest to correct answer, hurry please!
omeli [17]

company A :

30,000 + 0.03(37499) = 31124.97...sales less then 37500

30,000 + 0.03(37501) = 31125.03....sales exceed 37500

30,000 + 0.03(249000) = 37470 ...sales less then 250000

30,000 + 0.03(251000) = 37530....sales exceed 250000


company B :

25,000 + 0.05(37499) = 26874.95...sales less then 37500

25,000 + 0.05(37501) = 26875.05...sales exceed 37500

25000 + 0.05(249000) = 37450...sales less then 250000

25,000 + 0.05(251000) = 37550...sales exceed 250000


so i believe your answer is option b,

company A pays better when sales are less then 250,000, but company B pays better when sales exceed 250,000 <==
