What is the value of x?

Angelina_Jolie [31]

Answer/Step-by-step explanation:

well, first figure out how many units/times prism A was enlarged to become prism B...

16 ÷ 2 = 8

Now if we apply that info to the length of the prism, then...

80 ÷ 8 = 10

Therefore x = 10

And the Prisms remain congruent and proportional!

Identify the lower class limits, upper class limits, class width, class midpoints, and class boundaries for the given freque

Aleks [24]

Step-by-step explanation:

kindly find attached detailed information of the remaining information as requested for your reference

1. The lower class limit is the left number in the age column

i.e in the 25-34 the lower class limit is 25

2. The upper class limit is the right number in the age column

i.e in the 25-34 the lower class limit is 34

3. The class width is the difference between the class boundaries of a single class

class width = 34.5-24.5= 10

4. The number of individuals is= 29+34+16+3+5+1+2= 90

MATLAB Simulation. Develop a Matlab script to simulate the modulation of a 30 kHz carrier with a 0.5 kHz message signal. Use 40%

iren2701 [21]

Answer:

MATLAB code for DSB-SC modulation.

fc=154000; % carrier signal frequency

fm=fc/10; % message signal frequency

fs=100*fc;

t=0:1/fs:4/fm;

xc=cos(2*pi*fc*t);

xm=10*cos(2*pi*fm*t); % amplitude of sinusodial is 10

figure(1)

subplot(2,1,1),plot(t,xc);

title('carrier signal of 154 khz');

xlabel('time (sec)');

ylabel('amplitude');

subplot(2,1,2),plot(t,xm);

title('message signal of 15.4 khz');

xlabel('time (sec)');

ylabel('amplitude');

% DSB-SC MODULATION

z1= xm.*xc;

figure(2)

subplot(2,1,1),plot(t,z1);

title('DSB-SC MODULATION IN TIME DAOMAIN');

xlabel('time (sec)');

ylabel('amplitude');

l1=length(z1);

f=linspace(-fs/2,fs/2,l1);

Z1=fftshift(fft(z1,l1)/l1);

subplot(2,1,2),plot(f,abs(Z1));
