The first choice,
... a. s(t) = ac[1 + μam cos (2πfmt)] cos (2πfct)
has the carrier frequency cos(2πfct) amplitude modulated by the message signal.
The other expressions represent frequency and phase modulation of various kinds.
C= Clarence, J= Juan, and D= Darlene
C= 3J-5
D= C/2+2
J= c
Answer:
Center = (1,2) radius = 2
Step-by-step explanation:
I used Demos to graph the circle.
Then I added two line to find the center of the circle
The radius is 2
8/1/2=10/n=2*(n-15)/3n*3n=0*3n. Now we do, 2*(n-15)=0, which gives us 2=0. N-15=0. So n=15. Therefore, the answer is n=15.
If you mean surface area, the answer is 351.68 if you meant surface area for volume and l(length) for h. if not then I hope the surface area may have helped in finding your answer.
