The height \( h \), in feet, of a projectile can be modeled 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 initial 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 soccer player kicks a soceer ball from the ground with an initial vertical velocity of var : \( v 0 \) feet per secoad. When will the ball land back on the ground? Round to the nearest tenth of a second. Enter the correct value in the box. Show Hints The ball will land on the ground again in \( \square \) second(s).

10. Jika \( g(x)=x+3 \) dan \( (f \circ g)(x)=x^{2}-4 \), maka \( f(x) \) adalah \( \begin{array}{l}\text { A. } \\ \text { B. } x^{2}-1 \\ \text { C. } x^{2}-6 x-5 \\ \text { D. } x^{2}-6 x+5 \\ \text { E. } x^{2}+6 x+5\end{array} \)

Select all that apply. \( \begin{array}{ll}\text { QA. } 2+\frac{2}{5} x+1 & \text { ロB. } 2+\frac{x}{5}+1 \\ \square \text { C. } \frac{4}{5} x-\frac{1}{5} x+3 & \text { ロD. } \frac{2}{5} x+3 \frac{3}{5} x-1 \\ \text { पE. } 2+\frac{3}{5} x+1 & \text { ロF. } \frac{2}{5} x+3 \frac{1}{5} x\end{array} \)

An angle measures \( 82^{\circ} \) more than the measure of its supplementary angle. What is the measure of each angle? \[ \square^{\circ} \text { and } \square^{\circ} \]

Solve for \( z \) \[ \begin{array}{l}3 z=24 \\ z=\square\end{array} \]

The measure of an angle is eight times the measure of its complementary angle. What is the measure of each angle?
