Suppose x(t) is the continuous-time function given by x(t) = 1 on the interval [0; 1] and x(t) = 0 elsewhere. a) Calculate the c

ontinuous time Fourier transform of x(t). Call this X(j????). b) Suppose x1 (t) = x(2t). Provide the explicit definition for x1 (t) (i.e. over what interval

Answer:

a) X( w ) = 1 /jw -   e^-jw / jw

b) X1(t) = 1  for  0.5  

   X1(t) = 0 for elsewhere

Step-by-step explanation:

x(t) continuous time function = 1

interval ( 0,1 )   also x(t) = 0 outside the given interval

a) Determine the continuous time Fourier transformation of x(t)

x( t ) = u(t) - u(t - 1 )

x ( w ) = 1 /jw -   e^-jw / jw

b) supposing x1(t) = x(2t)

x1(t) = u(t) - u ( t - 0.5 )

x1(t) = 1  for  0.5  

x1(t) = 0 for elsewhere

Please help me with math please, they are number lines
Brums [2.3K]
So u have to rearrange to find x.
First u multiply by - 2 to get rid of the fraction bit
This leaves u with - 46>/x-49
Now u have to get x on its own which means you have to get rid of - 49 and to do this the opposite of - 49 is +49, so you would ADD 49
This gives you 3>/x

And the number line which represents this is B.

Find the volume of the sphere. <br> Either enter an exact answer in terms π or use 3.14 for π
Lunna [17]

The equation for volume of a sphere is (4/3)(pi)(r)^3. So you would plug in he radius 9 into the equation. It would simplify to equal (4/3)(pi)(729). It simplifies further to equal (972)(pi)

Principal: $4,000 at 6% for a) 4 years, b) 4 months, and c) 4 days.
ZanzabumX [31]

Answer:

If you're asking for the interest:

a) 960

b) 80

c)2.63 approx.

Step-by-step explanation:

interest = principal x rate x time OR I = prt

TIME IS IN YEARS.

Thus, the first would be I = 4000 *4 *6%% = 960

Second: 4 months = \frac{1}{3} year

I = 4000x\frac{1}{3}x6% = 80

Third: t = 4 days =\frac{4}{365}year

I = 4000x6%x\frac{4}{365} ≈ 2.63
