2 A) Use integration by parts to show $-\Theta'(a) = \int_{-\infty}^{\infty} \Theta(x)\delta'(x-a)dx$. Here and moving forward the prime, ' indicates a derivative in this case with respect to x. B) Within the integral let $\Theta(x) = x\psi(x)$ and show you obtain $-\psi(0) = -\int_{-\infty}^{\infty} \psi(x)\delta'(x)dx$. This means, that in shorthand $x\delta'(x) = -\delta(x)$ (of course inside an integral).

State labels do not need to be like S0 and can in fact be anything you like. This can be quite useful for keeping track of the meaning of states if there are a lot of them. In some sense, in modern computers the state labels are given by the bit string which is the contents of the memory, and the operations that the computer does are operations on the state labels. Construct a finite state automaton that recognises all strings over the alphabet \{a, b, c\} that have at least one a, at least one b, and at least one c. Give your answer as a state change diagram. Give your states meaningful labels.

12. [-/10 Points] DETAILS SERPSE10 4.3.P.017. MY NOTES ASK YOUR TEACHER A boy stands on the deck of the boat and tosses a rock into a lake. The rock is thrown from a height of 2.50 m above the water surface with a velocity of 4.40 m/s at an angle of 60.0° above the horizontal. As the rock strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the rock enters the water, it moves in a straight line in the direction of the velocity it had when it struck the water. If the lake is 2.30 m deep, how much time elapses (in s) between when the rock is thrown and when it strikes the bottom of the lake? 5 Need Help? Reed It
