Step-by-step explanation:
Answer: Pressure(t) = 5mP*sin(191.08*t)
Step-by-step explanation:
The information we have:
Maximum pressure P = 5 mP
frequency = 1200Hz
Period = 1/frequency = (1/1200) seconds
when t = 0, P = 0, so we should use a sin function (because sin(0) = 0)
Then we can write this as:
Pressure(t) = P*sin(c*t)
where t is time in secnds, P is the maximum pressure 5mP, and c is a constant that depends on the period.
Pressure(t) = 5*sin(c*t)
knowing that the period is 1/1200 seconds, we have that:
c*1/1200 s = 2*3.14
c = 1200/(2*3.14) 1/s= 600/3.14 1/s
Our function is
Pressure(t) = 5mP*sin(191.08*t)
Answer:
75.4
Step-by-step explanation:
Answer:
8 days
Step-by-step explanation:
The total cost includes $55 flat rental fee which is one time cost only as not given everyday so we subtract it from $123 and divide $(123-55) with per day cost that is $8.50 which gives 8 as answer so Val spent 8 days on vacation.
Step-by-step explanation:
500+60000=60500
