Let $y = \begin{bmatrix} 6 \\ -9 \\ 5 \end{bmatrix}$, $u_1 = \begin{bmatrix} -2 \\ -5 \\ 1 \end{bmatrix}$, $u_2 = \begin{bmatrix} -4 \\ 1 \\ -3 \end{bmatrix}$. Find the distance from y to the plane in $\mathbb{R}^3$ spanned by $u_1$ and $u_2$. The distance is $oxed{}$ (Type an exact answer, using radicals as needed.)

3(a) Design a synchronous counter with an external input X. When X = 1, the counter goes through the state sequence 1, 4, 3, 6, 2, 5 and repeats. With X = 0, the counter counts in the reverse direction. For states 0 & 7 assume don't cares as your next states. Design the counter using D flip-flops and minimum logic gates. Draw the logic diagram. Show all steps. (b) From your design, what will be the next state if the counter starts in '0' state with X = 1 on power up? (Answer this part once your design is completed.)
