I need help with geometry<br> I know its not the first one

alukav5142 [94]

Answer: ASA, C

Step-by-step explanation:

I think it's ASA cuz since the lines indicate they are parallel, then you can find that the two interior angles are also congruent. Since two angles are the same with the side inbetween being the same, it's probably asa.

(with steps please) Find the inverse Laplace transform, f(t), of the function: 16/(s-4)^3

Stells [14]

Answer: The required inverse transform of the given function is

$f(t)=8t^2e^{4t}.$

Step-by-step explanation: We are given to find the inverse Laplace transform, f(t), of the following function :

$F(s)=\dfrac{16}{(s-4)^3}.$

We have the following Laplace formula :

$L\{t^ne^{at}\}=\dfrac{n!}{(s-a)^{n+1}}\\\\\\\Rightarrow L^{-1}\{\dfrac{1}{(s-a)^{n+1}}\}=\dfrac{t^ne^{at}}{n!}.$

Therefore, we get

$f(t)\\\\=L^{-1}\{\dfrac{16}{(s-4)^3}\}\\\\\\=16\times\dfrac{t^{3-1e^{4t}}}{(3-1)!}\\\\\\=\dfrac{16}{2}t^2e^{4t}\\\\\\=8t^2e^{4t}.$

Thus, the required inverse transform of the given function is

$f(t)=8t^2e^{4t}.$

SomeonePLEASE help if u do ily:(

pav-90 [236]

Answer:

Step-by-step explanation:

Pythagorean Theorem

a^2+b^2=c^2

C is the hyptonuse A and B are legs.

a^2+3^2=5^2

a^2+9=25

a^2=16

a= sqrt16

a=4

Hope this helps!
