Use theorem 7.1.1 to find {f(t)}. (write your answer as a function of s.) f(t) = t2 + 5t − 6 {f(t)} =

bulgar [2K]

General Idea:

Let $f$ be a function defined for $t\geq 0$ . Then the integral

$L\{f(t)\}=\int\limits^\infty_0 {e^{-st}f(t)} \, dt$

is said to be Laplace transform of $f$ , provided that the integral converges.

$L\{1\}=\frac{1}{s} \\ \\ L\{t^n\}=\frac{n!}{s^{n+1}} , \; \; \; n=1,\;2, \;3,...$

Applying the concept:

$L\{f(t)\}=L\{t^2\}+L\{5t\}-L\{6\}=\frac{2}{s^3} +\frac{5}{s^2} -\frac{6}{s}$

The stock of Company A gained 2% today to $27.03. What was the opening price of the stock in the beginning of the day?

Luden [163]

Answer:

The price of the stock in the beginning of the day was $26.5.

Step-by-step explanation:

This question can be solved using a rule of three.

The initial stock of the company, that we want to find, was 100% = 1.

$27.03 is an increase of 2%, so it is 100+2 = 102% = 1.02%. So

$27.03 - 1.02

$x - 1

$1.02x = 27.03$

$x = \frac{27.03}{1.02}$

$x = 26.5$

The price of the stock in the beginning of the day was $26.5.

Given g(x)=(x^2)-8/x+4, find g(10). Please Help

kramer

Answer:

Step-by-step explanation:

Hello,

I assume that you mean $g(x)=x^2-\dfrac{8}{x}+4$

Replace x by 10

$g(10)=10^2-\dfrac{8}{10}+4=104-0.8=103.2$

thanks
