...Algebra II? The problem states:
Wind speed typically varies in the first 20 meters above the ground. Close to the ground, wind speed is often less than it is at 20 meters above the ground. For this reason, the National Weather Service usually measures wind speeds at heights between 5 and 10 meters. For a particular day, let the formula f(x)=1.2 ln x +2.3 compute the wind speed in meters per second at a height x meters above the ground for x > 1. The > has a line underneath it though, but I don't have that on my laptop. I am trying to find the steps on how to solve this. How would I go about graphing it? What would Y1 or Y2 be?
a) Find what the wind speed at a height of 5 meters.
b) Graph f in the window [0,20,5] by [0,7,1], Interpret the graph. What does that mean to "interpret"?
c) Estimate the height where the wind speed is 5 meters per second.
Thanks in advance for any help.
This is the only problem I have no idea what I am doing.
