Answer:

D. after 3 minutes, Sam is 40 meters from the dock.

Explanation:

For an input of 3, the function will produce a value of 40. That is in 3 minutes, the boat would have covered a distance of 40meters.

We can solve this problem using the given graph.

We know that this is a distance - time graph. The slope of this graph gives the value of the speed of the boat.

  • From the time - axis, mark point 3 which corresponds to the input given.
  • Trace it up to the point where it coincides with the graph.
  • Then find the distance axis value of the point.
  • Doing this yield 40m

So, in 3 minutes, Sam will row a distance of 40m.

As soon as a tsunami approaches the coast, its speed decreases considerably. This is because the speed of a tsunami depends on the depth of the water; the lesser the depth of the water, the lesser the speed of an approaching tsunami. However, there is no change in the overall impact of a tsunami.

explain two reasons as to whether or not you believe sustainability is an unattainable object next determine two barriers curren
levacccp [35]

Answer and Explanation:

Sustainability is feasible with enhancements in innovation. Current advances make it conceivable to run feasible businesses, yet these are monetarily unfeasible because of our enormous vitality needs.The proficiency of current innovations in changing over vitality to progressively usable structures for example sun powered, wind,tidal and so forth are likewise low, mostly because of innovative boundaries, making huge scale maintainability unachievable,despite the accessibility of enough crude vitality to suit human needs. Consequently, we have the crude vitality lying around, we should simply change over it to a usable structure. Therefore, levels of progress at littler scales just as the nearness of crude vitality for enormous scale support ability are two reasons why manageability is reachable

As referenced above,the primary hindrance to accomplishing supportability is an absence of innovation to understand this. Another significant obstruction is the tremendous populace. A higher populace requests higher vitality, consequently, considerably more vitality should be delivered. At lower levels, manageability is all the more effectively come to even with our current innovative head ways. With a lower populace, while we may not accomplish manageability completely, we could at present bear to utilize assets in a progressively controlled way, and not deplete our current stores at a disturbing rate while we anticipate advancements in economical innovations.

One more boundary is our monetary framework which rewards snappy and quick generation over maintainable development, in this manner organizations will in general center around amplifying benefits instead of accomplishing supportability.
