g show that the hamiltonian-path problem from exercise 34.2-6 can be solved in polynomial time on directed acyclic graphs. give
NISA [10]

The efficient algorithm can be given in polynomial time.

For this particular problem ,we could find a polynomial time solution for it and then it is proven it could be solved in polynomial time.

1. You must have a source node with an in-degree of zero for a directed acyclic graph, so look for a path in the original graph G that has that value. Since each node must be visited, there is no solution if there are multiple nodes. However, the zero degree should be visited first, and if there are multiple points, there must be some nodes that cannot be visited initially.

2. Assuming that the left graph is G', remove the source node with in-degree zero and its surrounding edges to find the next node to start at.

3. As I mentioned in 1), there is no way to visit those nodes since their in-degree is zero and there should only be one to visit after its predecessor. If the left graph G' has more than two nodes or vertices with the in-degree of zero, then we could conclude that it is unsolvable.

4. Continue performing step 3 until we reach the endpoint, where there are no more nodes to visit. If there are some nodes that are not visited but we can't find an edge to get to them, then the problem cannot be solved; otherwise, we ought to have the answer.

We have discovered the answer to the Hamiltonian-path from the aforementioned steps.

its complexity is O(|E|+|V|) where E is number of edges and V is number of vertexes in directed acyclic graph because from v_{1} to v_{n}, we must trace the vertices and their surrounding edges. It is completed in polynomial time, as we are aware.

4. Name the first five terms of the arithmetic sequence. a1 = -35, d=4​
eduard

Answer:

Step-by-step explanation:

We first have to write the equation for the sequence, then finding the first five terms will be easy. Follow the formatting:

a_n=a_1+d(n-1) and we are given enough info to fill in:

a_n=-35+4(n-1) and

a_n=-35+4n-4 and

a_n=-39+4n or in linear format:

a_n=4n-39 where n is the position of the number in the sequence. We already know the first term is -35.

The second term:

a_2=4(2)-39 so

a_2=8-39 and

a_2=-31

The third term:

a_3=4(3)-39 and

a_3=12-39 so

a_3=-27 and we could go on like this forever, but the nice thing about this is when we know the difference all we have to do is add it to each number to get to the next number.

That means that the fourth term will be -27 + 4 which is -23.

The fifth term then will be -23 + 4 which is -19. You can check yourself by filling in a 5 for n in the equation and solving:

a_5=4(5)-39 and

a_5=20-39 so

a_5=-19

What is the parent equation for exponential growth and decay?
Archy [21]

Answer:

A = P x r^t

Step-by-step explanation:

A = Amount (e.g. number of organisms in population after certain period of time)

P = Principal/ Initial Value (e.g. the starting population)

r = rate as a decimal (e.g. if a population increases over certain period of time by 20%, r would equal 1.2)

t = time in whichever units you need.

Example of problem using formula:

A population of 2000 decreases by 20% every year, find the population size after 5 years.

A = ?

P = 2000

r = 0.8

t = 5

A = Pxr^t

A = 2000 x 0.8^5

A = 655.36

Hope this helped!

A chord of a circular clock is 48 inches long, and its midpoint is 7 inches from the center of the circle. What is the radius of
Sphinxa [80]

ANSWER

The radius is 25 inches

EXPLANATION

From the diagram, the radius of the circle is AC.

From the Pythagoras Theorem,

{r}^{2}  =  {7}^{2}  +  {24}^{2}

r^{2}  =  49 +  576

Simplify

r^{2}  = 625

Take positive square root,

r =  \sqrt{625}

r = 25

Hence the radius is 25 inches
