\( \frac { \overline { x } } { m } < \frac { 1 } { n } \quad m \cdot n \neq 0 \)

The height \( h \), in feet, of a projectile can bo modelod by the equation \( h(t)=-16 t^{2}+v_{0} t+h_{0} \) where \( t \) is the time in seconds, \( h_{0} \) is the projectile's ini height in feet, and \( v_{0} \) is the projectile's initial vertical velocity in feet per second. Solve the projectile motion problem by completing the square. A lacrosse playor throws a ball into the air from a hoight of 8 foet with an initial vertical volocity of 30 feot per second. When will the ball hit the groun Round to the nearest tenth of a second. Enter the correct value in tho box. Show Hints The ball will hit the ground in \( \square \) seconds.

Factor completely: \[ 32 v^{3}-2 v^{3} x^{4} \]

Add. \[ \frac{-5}{8 w^{2} y}+\frac{3}{4 w y^{2}} \] Simplify your answer as much as possible.
