Ferris Wheel Question

  1. Jun 20, 2016 #1
    1. The problem statement, all variables and given/known data
    Ferris wheel has radius of 7m and its highest point is 15.5 m off the ground. It takes 45 seconds to complete one revolution. State the domain and range.

    2. Relevant equations


    3. The attempt at a solution
    I know that the domain is D:{0<=t<=45}s
    But for the range I thought the range was R:{1.5<=h<=15.5} but in the answer key it says range is R:{1.5<=h<=17.5} and I'm having troubling understanding why it's 17.5? Can someone help me figure it out.

    That is not provided in the question, unless I have to find it?

    I can guess that you are referring to the domain and range of the function which relates the elevation of some point on the Farris Wheel to time. But it's just a guess on my part.

    If this is the case, then you are referring to the elevation of said point as a function of time, as the Farris Wheel rotates.

    If you stated the question correctly, then your answer is right and the answer key is wrong.

    That's what I was thinking. Thanks though.
