The slope of the inverse is 1/2.
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.
<h3>
Answer:</h3>
95%
<h3>
Step-by-step explanation:</h3>
4 minutes is 4×(60 seconds) = 240 seconds.
The amount of dance time is (240 -12) seconds = 228 seconds.
The percentage of music time spent dancing is ...
... (228 seconds)/(240 seconds) × 100% = 95%
It would be 10 to the right when you add from 0
Answer:
The number x = 3
Step-by-step explanation:
Let 'x ' be the positive integer
Given data If the sum of five times a number and two times the same number and the same number is increased by 4 and the result is 25
sum of five times a number is 5 x and same number two times is 2 x and increased by 4 (addition) then result is equal to 25
so finally 5 x +2 x +4 = 25
7 x + 4 = 25
subtracting '4' on both sides , we get
7 x = 21
dividing '7' on both sides, we get
Therefore the number is x = 3
<u>Verification :</u>-
5 x +2 x +4 = 25
substitute x = 3 in above equation
15+6+4 = 25
25 =25
<u>Final answer</u> :-
The number is 3
