Four times d to the third minus ten
Answer:
0.637
Step-by-step explanation:
The average value of a whole sinusoidal waveform over one complete cycle is zero as the two halves cancel each other out
Letter B would be the answer.
2L + 2(1/2L) = 90
2L + L = 90
3L = 90
L = 30
(1/2)(30) = 15
W = 15
CHECK:
30 + 30 + 15 + 15 = 90
