The model that describes how data is written to a blockchain is the: append-only data structure.

<h3>What is an Append-only Data Structure?</h3>

Append-only is computer data storage property whereby new data can be added to a blockchain, like an additional block, in a time-ordered sequential order in such a way that the data added cannot be easily altered as al data are permanently stored across all nodes.

The append-only data structure makes data stored almost immutable. This is the model in which the blockchain technology is built on.

Therefore, the model that describes how data is written to a blockchain is the: append-only data structure.

Twice as many trained workers are permitted to immigrate to the United States as in the past. Explain the impact on economic gro

mixas84 [53]

Answer: There will be an increase in economic growth as more output will be supplied at lower prices.

Explanation:

When twice as many workers are allowed to move to the United States, this will lead to a surplus in the labor market. The surplus in the labor market will lead to the reduction in wages as the workers will compete with one another.

The competition will lead to decrease in wage rates and the business costs decrease as well. This will in turn, lead to the reduction in the price level and an increase in the quantity supplied. The rightward shift will cause movement along the aggregate demand curve, as there will be more output to be supplied at a lower price level.

Clint wants to keep a young tree from blow- ing over during a high wind. He decides that he should tie a rope around the tree at

Sergio039 [100]

Answer:

No, the 270 cm rope Clint has is not enough to do the job.

Explanation:

The height of tree where rope has to be tied = 180 cm

The distance of the stake from the base of the tree = 200 cm

We can say that the arrangement makes a right angle triangle, with the right angle situated at the base of the tree. The figure is attached below. Consult it for better understanding.

Length of the rope can be found by using Pythagoras theorem.

(Length of rope)² = 180² + 200²

Length of rope = 269 cm

As it is stated the additional 30cm of rope is required for tying from both ends. Total length of rope required is:

Total length of rope = 269 + 30

Total length of rope = 299 cm

As length of rope required is 299cm, the 270 cm rope Clint has is not enough to do the job.
