2. Give recursive definitions for the following sets. a. The set of all strings over {a, b} containing at least one "a". b. The set of odd-length binary strings that end with 00.

Two definition of sets of all strings and sets of odd length binary are given

Step-by-step explanation:

A.) Suppose A is the string of contain at least one a:A = a

B will be same as it is b:B = b

Sets of the union of the AB  and BA in which A followed B and corresponding B will follow A. Set = will (AB) (BA) = (*a*, *b*) (*b*, *a* )….

B.) There is the regular expression is compared with two 00 which is surrounded by the 0+1 that accepted at least two 0s.

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
