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:
12. We have that 32 cm is the shaded region
- 7×6=42
- 42-33cm= 9cm
- Hence the white are is 9cm
- Then 8×9=72 cm
- 72cm -9cm= 63 cm^2
8 x 64
=64 x 2 x 4
=128 x 2 x 2
=256 x 2
=512
Answer:
The line segment 7 cm long is shown below.
Step-by-step explanation:
First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts.
The length of each part is 1 cm.
Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.
From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is

Hence the total length of line is 7 cm.
Answer:
<u>B. $0.32</u>
Step-by-step explanation:
You divide the cost of the cereal box ($3.84) with the number of ounces (12).
3.84 / 12 = 0.32
