    1. (a) The tangent line is a straight line that touches a function at one point and because we are talking about hiking on a mountain, the tangent line will give us an indication of how high our hiker has traveled and thus, show us the difficulty of the hike.
    (b) The slope of the tangent line is pretty small
    (c)For this part I used differentiation
    e(x)=125x^2-6.25x^3
    125*(2)x-6.25*(3)x^2
    e'(x)=250x-18.75x^2 (In miles)
    (d) For this part I used the derivative to find the place it equals to zero or the place it reaches the highest point
    0=250x-18.75x^2
    0=x(250-18.75x)
    0/x=x(250-18.75x)/x
    0=250-18.75x
    -250=-18.75x
    x=13 1/3 or 13.33333333333333 miles
    (e) Using what we got in (d), we can now get the highest point on the trail by using the original equation
    e(x)=125x^2-6.25x^3
    =125(13.33333333333333)^2-6.25(13.33333333333333)^3
    =7407.407407
    About 7407 feet
