Two rocks are lauched straight up in the air. The height of Rock A is gived by the function \(f\), where \(f( t) = 4+ 30t- 16t^ 2\). The height of Rock B is given by \(g\), where \(g( t) = 5 + 20t - 16t^ 2\). In both function, \(t\) is time measured in seconds and height is measured in feet.

a. determine which rock hits the ground first.

b. Rock A, modeled by f(t) hits the ground at about ____ seconds.

c. Rock B, modeled by g(t) hits the ground at about ____ seconds.

Complete each conversion by using unit factors. Round to the nearest hundredth. Example: 

\(34 \frac { kg} { hour} = -\frac { punces} { minutes} \) 

1. \(25 \frac { kg} { hour} = \frac { ounces} { minutes} \)

2. \(9\frac { miles} { day} = \frac { meters} { hour} \)

3. \(20777\frac { cm^ 2} { hour} = \frac { in^ 2} { second} \)
