Solve the equation and check your solution. (If there is no solution, enter NO SOLUTION.) \[ \frac{2}{3 x+1}-\frac{27 x}{3 x-1}=-9 \] \( x=\square \)

(a) A ball throw upward from the roof of a building which is 750 feet high will be at a height of \( h \) feet after \( t \) seconds as described by the function. \[ h=f(t)=-16 t^{2}+50 t+750 \] (i) What is the height of a ball after 5 seconds? (ii) What is the velocity of the ball after 5 seconds (iii) What is the acceleration of the ball at \( t=0 \) ? At \( =5 \) ? (b) Find a, b, c and d so that \( \left.\qquad \left.\left[\begin{array}{rr}1 & -2 \\ 2 & -3\end{array}\right] \right\rvert\, \begin{array}{ll}a & b \\ c & d\end{array}\right]=\left[\begin{array}{ll}1 & 0 \\ 3 & 2\end{array}\right] \)

\( f ( x ) = \frac { 1 } { x } \sin x \neq 0 \)
