You should try both points
put x=5/2 and y=3
5-2=3
the first one is on the graph
put x=3/2 and y=20
3-40/3≠3
the second one is not on the graph
Answer:
21.5?
the more i think the more i believe it
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.
If you’re suppose to use pi=3.14 then your answer is correct. but if they didn’t say to use pi as 3.14, then look at my working! hope this helps!
