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.
Answer:
300 cm
Step-by-step explanation:
8 x 2.5 = 20
6 x 2.5 = 15
20 x 15 = 300 cm²
4x+16=-2
Subtract 16 from both sides
4x=-18
Divide both sides by 4
x=-18/4
x= -9/2
Final answer: x=-9/2
