Design a pda recognizing each of the following languages:
(1) {w | w = a nb n , n is odd}
(2) {w | w = w r and length of w is odd }
(3) {w | w = a nb 2n , n ≥ 1 }
(4) {w | w = a nb n+mc m, n ≥ 0, m ≥ 1 }
(5) {w | w = a 2nb 3n , n ≥ 0 }
(6) {w | w = a nb m, n ≥ 1, m ≥ 1 and n 6= m }

i cant see the graph

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
