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

The function f(x) = 7x-m/2-nx, find the values of m and n such that the vertical asymptote is x=6, and the x-intercept is 5.
Reil [10]
The function is f(x)= (7x-m)/(2-nx)
<span>the vertical asymptote is x=6, that means 2/n = 6 or n=1/3
</span>
And now, we have f(x)=(7x-m):(2-1/3x)= (14x-2m): (6-x)

<span>the x-intercept is 5 and we have y=0, x=5. So we obtain 0=(70-2m):(6-5)
or 70-2m=0, m=35

Conclusion m=35 and n=1/3</span>

Someone help me with this algebra (if u can’t see it flip your device ) really need the answers
vlabodo [156]

Answer:

The first one is x = 19

The second one is x = 17

Step-by-step explanation:

The first one:

(4x + 3) + (x - 8) = 90 ---> becasue the angle is 90 degrees

substitute 19 and check

The second one:

(7x + 10) + (3x) = 180 ---> because the angle is 180 degrees

substitute 17 and check

Hope this helps! :]
