What is the difference between Laplace Transform and fourier Transform?

marta [7]

Real time mapping of a function to a new function is known as Fourier transforms. The new mapped function is defined for an interval of (-∞, ∞).

<span>While the Laplace transform is the counterpart, in which a function is mapped to a new function on complex plane. Functions defined for span t≥0 are used by Laplace transformation. </span>

Help please<br><br> Geometry test

ahrayia [7]

Step-by-step explanation:

To find x,

$21x - 9 = 117$

$21x = 126$

$x = 6$

To find arc AB,

$21(6) - 9 = 117$

To find Arc AE,

$117 + x = 180$

$x = 63$

Arc ABC,

$117 + 63 = 180$

ACE

$180 + 27 + 90 = 297$

Identify BR rounded to the nearest tenth. HELP PLEASE!!

ahrayia [7]

Answer:

<h2>BR ≈ 49.0</h2>

Step-by-step explanation:

Use cosine:

$cosine=\dfrac{adjacent}{hypotenuse}$

We have

$adjacent=42\\hypotenuse=BR\\\alpha=31^o$

$\cos31^o\approx0.8572$

Substitute:

$\dfrac{42}{BR}=0.8572$

$\dfrac{42}{BR}=\dfrac{8,572}{10,000}$ <em>cross multiply</em>

$8,572BR=420,000$ <em>divide both sides by 8,572</em>

$BR=\dfrac{420,000}{8,572}$

$BR\approx49.0$

You planned to work on a project for about 4 and a 1/2 hours today.

Answer:

$2\frac{3}{4}$

Step-by-step explanation:

Given : You planned to work on a project for about 4 and a 1/2 hours today.

To Find :If you have been working on it for 1 and 3/4 hours, how much more time will it take?

Solution:

Total time to be spent on project today = $4\frac{1}{2}=\frac{9}{2} hours$

You have been working on it for hours = $1\frac{3}{4}=\frac{7}{4}$

Remaining time = $\frac{9}{2} -\frac{7}{4}$

= $\frac{11}{4}$

= $2\frac{3}{4}$

Hence it will take $2\frac{3}{4}$ hours more .
