We are doing a project with sinusoid graph problems. My group has done absolutely nothing, and it is due tomorrow. I am in desperate need of help. You have to know a bit about blood reading blood pressure, and relating it to heart rate. My teacher told me that I could use 60 beats per minute as my heart rate.
1. Frank has high blood pressure, and it is usually measured to be around 150/90mm. Normal blood pressure is usually considered to be around 120/80mm. Assume that both Frank and a "normal" person have a "normal" heart rate.
a. Find an equation, F(t), to represent Frank's blood pressure.
b. Find an equation, N(t), to represent normal blood pressure.
c. Graph both functions on the same coordinate plane.
d. When are the two blood pressures the same?
e. What are the first two times Frank's blood pressure hits 120mm?
This is the model equation : y = A sin or cos (B(x-c)) + D
He says he gave us "A", but I don't even know what number in the problem would be "A". I know that "B" is the period. Remember that 2pi/B is your period on the graph. C is what I think is the min or max. D would be your vertical shift.
Some of the variables may not be used. I am honestly not sure. I didn't do well when we studied sinusoid graphs, so this project is beyond impossible for me.
Thank you (:
