Answer:
The equation of the line is y = 6x - 2 .
Step-by-step explanation:
Formula for the equation of line is.
Where m is the slope.
As given
If (-6,-38) and (5,28) are two anchor points on the trend line.
Than
m = 6
Put the value in the equation of a line.
y = 6x +36 - 38
y = 6x - 2
Therefore the equation of the line is y = 6x - 2 .
Answer:
slope = - 3 y-intercept = 36
Step-by-step explanation:
12x + 4y = 144 , will allow this to be done.
so 4y = - 12x + 144
now dividing both sides of the equation by 4 will give
y = - 3x + 36 , which is now in the required form
slope = - 3 and y-intercept = 36
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)
