The graph shown below expresses a radical function that can be written in the form f(x)= a(x+ k)^1/n+C. What does the graph tell you about the value of n in this function?

Ahot-air balloon is 11.0 m above the ground and rising at a speed of 7.00 m/s. a ball is thrown horizontally from the balloon basket at a speed of 9.00 m/s. ignore friction and air resistance and find the speed of the ball when it strikes the ground.
