Answer:
Fs = 15 Hz > 12.7322 Hz
Hence, Nyquist theorem is NOT violated
Step-by-step explanation:
Given that;
a signal given by 15cos(20t) + 20sin(40t)
sampled at a rate of 15 Hz
Is the Nyquist theorem violated?
so;
from 15cos(20t) + 20sin(40t)
Freq F1 = 20/2π Hz
F1 = 3.1830 Hz
and
Freq F2 = 40/2π
F2 = 6.3661 Hz
Now, Nyquist's rate FN ≥ 2 × F_max
FN ≥ 2 × 6.3661
FN ≥ 12.7322 Hz
Now our given signal was sampled at a rate of 15 Hz
so, Fs = 15 Hz > 12.7322 Hz
Hence, Nyquist theorem is NOT violated
Answer:
Step-by-step explanation:
Circumference is given by this formula below. What gives us the radius.
The diameter of the circle is calculated by dividing the Circumference, 11304 in this case by 
The value of 3 in 3,456 is 3000 and the value of the 3 in 546,300 is 300 so you would multiply 3000*300 if I am correct.
I hope this could help.

A is correct because 445.50 Divided By 150 is Equal to $2.97.
