Answer:
a) see attached
b) period = 1/f ≈ 3.822 ms
Step-by-step explanation:
Apparently the pressure formula is ...
__
a) A graph of this for f=261.63 is shown in the attachment.
__
b) The period is the time T required to change the sine function argument by 2π:
2πfT = 2π
T = 1/f . . . . . . divide by 2πf
The period is the reciprocal of the frequency.
The period of the tone is 1/(261.63 Hz) ≈ 3.822·10^-3 s

Answer is in the picture in this post.
Answer:
x=3.4
Step-by-step explanation:
you want to subtract 4.2 from 5.9 so it will be 1.7. Then 1.7/0.5 and it will be 3.4
hope this helped
