Consider the following pushdown automata (pda) where s is the starting state and f is the favorable state:

(s, a, aa) ? (s, a); (s, a, ? ) ? (s, a); (s, b, a) ? (f, ? ); (f, b, a) ? (f, ? ); (f, a, a) ? (f, ? )

give the computation of the pda (give the state, input string still to be read, and top of the stack symbol (a, b, ? ) on the string aaabba, abbaaa, and baba. determine which of the strings are accepted by the pda.
determine the language accepted by the pda.

The total revenues for a company are $150,223 and the total expenses were 125,766. if you are calculating the net income, which of these spreadsheets would you use? insert a spreadsheet with $150,223 in cell b2 and 125, 766 in cell b3. enter a formula =b2-b3. the formula should be showing in the formula bar. insert a spreadsheet with $150,223 in cell b2 and 125, 766 in cell b3. enter a formula =b2+b3. the formula should be showing in the formula bar. insert a spreadsheet with $150,223 in cell b2 and 125, 766 in cell b3. enter a formula =b2/b3. the formula should be showing in the formula bar. insert a spreadsheet with $150,223 in cell b2 and 125, 766 in cell b3. enter a formula =b2*b3. the formula should be showing in the formula bar.
