In 1980, James planted a tree that was 1 foot tall. In 1996, that same tree was 81 feet tall. James finds that the height of the
tree can be modeled by the radical function () = vkt + 1 where H (t) is the height of the tree in feet, t, is the number of years since 1980, and k is a specific constant. What is
the value of k?
