A ball is thrown upward and outward from a height of 6 feet. The height of the ball, f(x), in feet, can be modeled by f(x) = -0.2x2 +1.7x+6
where x is the ball's horizontal distance, in feet, from where it was thrown. Use this model to solve parts (a) through (C).
a. What is the maximum height of the ball and how far from where it was thrown does this occur?
The maximum height is ___feet, which occurs ___feet from the point of release.
(Round to the nearest tenth as needed.)

i will take them

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
