GYMNASTICS A gymnast throws a baton up into the air during her floor routine. The height of the baton can be modeled by
y= -16^2 +24x + 4, where x is the time in seconds and y is the height of the baton in feet since it was released. The celling of
the gym can be represented by the function y = 42.
a. Solve the system of equations algebraically.
b. Will the baton reach the ceiling of the gym? Explain your reasoning.

Prove (a) cosh2(x) ā sinh2(x) = 1 and (b) 1 ā tanh 2(x) = sech 2(x). solution (a) cosh2(x) ā sinh2(x) = ex + eāx 2 2 ā 2 = e2x + 2 + eā2x 4 ā = 4 = . (b) we start with the identity proved in part (a): cosh2(x) ā sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 ā sinh2(x) cosh2(x) = 1 or 1 ā tanh 2(x) = .
