9. Which of the following are true for all regular languages and all homomorphisms? (a) h (L1 ∪ L2)= h (L1) ∩ h (L2). (b) h (L1

mixer [17]

Answer:

h (L1 ∪ L2)= h (L1) ∩ h (L2).

This is true.

There will be w ∈ (L1 ∪ L2) for any s ∈ h (L1 ∪ L2) in such a way that s=h(w)

we can assume that w ∈ L1

So In this case h(w) ∈ L (S1). Hence s ∈ L(S1)

for any s ∈ h (L1) U h(L2)

We can assume that s ∈ L(S1)

There exists w ∈ L1 such that s= h(w)

In this case it is w ∈ L1 U L2 as well.

Hence , s ∈ h (L1 U L2)

Explanation

consider = 0,1 and = a,b and h(0) = a , h(1) = ab

(a) Consider L1 = 10,01 and L2 = 00,11

Now L1 ∪ L2 = 00,01,10,11

h (L1 ∪ L2) = h(00) , h(01) , h(10) , h(11) = h(0)h(0) , h(0)h(1) , h(1)h(0) , h(1)h(1)

= aa, aab , aba , abab

Hence h (L1 ∪ L2) = aa, aab , aba , abab .

Here h (L1) = h(10) , h(01) = h(1)h(0) , h(0)h(1) = aba , aab

Hence h (L1) = aba , aab .

Here h (L2) = h(00) , h(11) = h(0)h(0), h(1)h(1) = aa, abab

Hence h(L2) = aa, abab.

Finally Hence , h (L1 ∪ L2)= h (L1) ∩ h (L2).

Use the AND function with appropriate arguments in cell H11 to determine if there is a force out at third base. There is a force

Pie

Answer:

=AND($C11 = "Yes", $D11 = "Yes")

Explanation:

The AND function takes conditional inputs and tests if each of them are TRUE. If all of the inputs are TRUE, the function will output TRUE but if any one of them are not the function will output FALSE. This scales to multiple inputs but this example only has two conditions. It is important to remember that we want to compare a string so our condition must be "Yes", not just Yes.

We also use a relative cell reference, "$", on the columns C and D since we always want to use the "Runner on 1st" and "Runner on 2nd" columns.

Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:

rosijanka [135]

Answer:

#include <stdlib.h>

#include <time.h>

#include<iostream.h>

int main(void) {

int seedVal = 0;

seedVal = 4;

srand(seedVal);

/* Solution*/

cout<<rand() % 149 + 100<<endl;

cout<<rand() % 149 + 100<<endl;

return 0;

}

Explanation:

We start with the required include statements to enable use of srand, rand and time functions. I have also added iostream library to use "cout" function.

After that, the seed is initialized using srand(). And then the two rand functions are called with ranges including and between 100 and 149, and printed out.
