SOLUTION: I am trying to solve this problem. I get how to do part A. I don’t know how to graph this. What do I put for Y1 and Y2 (if anything)? And on part C. How did it come to about 7 mil

Question 273741: I am trying to solve this problem. I get how to do part A. I don’t know how to graph this. What do I put for Y1 and Y2 (if anything)? And on part C. How did it come to about 7 miles? I don’t understand where that comes from. The answer is in the back of the book. I have the TI-Nspire, but mostly use the TI-84 Silver Edition keypad.
The question is: Hurricanes are some of the largest storms on earth. They are very low pressure areas with diameters over 500 miles. The barometric air pressure in inches of mercury at a distance of x miles from the eye of a severe hurricane is modeled by the formula f(x) =0.48 ln (x+1) +27. It states
a) Evaluate f(0) and f(100).
b) Graph f in [0, 250, 1] by [25, 30, 1]
c) At what distance from the eye of the hurricane is the air pressure 28 Inches of mercury?
Thank you.... Answer by solver91311(24713) (Show Source):
I don't use graphing calculators, but a graph of your function looks like:
Part c:
The question: What is the value of required to make the value of be 28?
You need to solve:
If your calculator has an function (it might be the inverse of ), calculate the approximate value of . It comes out to just a bit more than 8 -- subtract 1 to get a result that is just a bit larger than 7.
