What is Confucian culture? Confucian culture is a cultural school with Confucianism as the guiding ideology, which has been respected by scholars and believers in all generations.

Confucianism was created by Kong Qiu in the Spring and Autumn Period. It advocated blood relations, worldly achievements, self-cultivation and preservation, and moral rationality. Its central ideas were forgiveness, loyalty, filial piety, fraternal love, courage, benevolence, justice, propriety, wisdom, and faith. Confucianism has been respected by generations of rulers for more than two thousand years, and has experienced the inheritance and development of Confucius's later learning.

Use the formula P=21+2w to find the width of a rectangle when the length is 18cm and perimeter is 48 ..

KIM [24]

Answer:

w=6

Step-by-step explanation:

P=2(L)+2(w)

48= 2(18)+2w

48=36+2w

12=2w

w=6

checking;

48= 2(18)+2(6)

48= 36+12

48= 48

(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

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

Convert 83% into a decimal<br> can you guy help me to do that

PilotLPTM [1.2K]

To convert a percentage to decimal form, you need to divide the number in the percent by 100. In reality, that just looks like moving the decimal point to the left two places.

83% / 100 = 0.83

83% in decimal form is 0.83.
Hope that helped! =)
