Question

a person's blood pressure is modeled by the function: P(x)=120+25sin(160pix) where P(x) is the pressure at time t measured in minutes. Give the period and frequency

Answer 1

equation look like this: P(x)=\[120+25\sin (160\Pi x)\]

Answer 2

We need to get the given equation in the form of the one in the attachment so that we can identify the period and frequency.

Answer 3

ok... did you see what directrix pulled up?

Answer 4

yes

Answer 5

still there?

Answer 6

period is defined as 2pi/B.
what is your B in your model?

Answer 7

i'm here and B is 160 pi right?

Answer 8

yes.. so Period = 2pi/B
what's your period?

Answer 9

2pi/160pi, right? (sorry laptop is slow)

Answer 10

yes... can you simplify that?

Answer 11

80pi

Answer 12

don't the pi s cancel?
