E. The object’s average speed during the time interval from 1 s to 3 s is 13.5 ft/s.

B. An estimate of the object’s instantaneous speed at t = 3 seconds is 5.4 m/s.

<h3>What is average speed?</h3>

The average speed of an object is the ratio of total distance traveled by object to the total time of motion of the object.

position of the object at 1 second = 2.7 ft

position of the object at 3 seconds = 24.3 ft

total distance traveled by the object = 2.7 ft +  24.3 ft = 27 ft

total time = 3 - 1 = 2 seconds

average speed = 27 ft / 2 s

average speed = 13.5 ft/s

<h3>What is instantaneous speed?</h3>

This is the speed of the object at a specified time.

speed = distance/time

speed at 3 seconds  = 16.2 m / 3 s

speed = 5.4 m/s

Thus, the object’s average speed during the time interval from 1 s to 3 s is 13.5 ft/s.

An estimate of the object’s instantaneous speed at t = 3 seconds is 5.4 m/s.

(a) If you toss 10 coins, what percent of the time will you get the three most likely macrostates (6 heads and 4 tails, 5 heads
FromTheMoon [43]

This question is incomplete, the microstates table is left out which will be uploaded along this answer;

Answer:

a) the required is 65.6%

b) the required time is 4.2666 hrs

Step-by-step explanation:

using the microstates from the table in the diagram;

a)

the percent times the above any of the above microstates occurs is;

% (6 heads and 4 tails, 5 heads and 5 tails, 4 heads and 6 tails)

=   ((210 + 252 + 210)/1024) × 100

= 0.6562 × 100

= 65.6%

Therefore the required is 65.6%

b)

the probability of getting 10 heads and 0 tail or 0 tail head and 10 tails is;

p( 10H, 0T or 0H, 10T = 2/1024

= 1/512

so on average, it will take 512 trails or at a rate of 2 trials/min, 256 mim in hours;

(256 min) ( 1h/60min) = 4.2666 hrs

Therefore the required time is 4.2666 hrs

A triangle with 7,?, and form a right triangle.
Vlad1618 [11]

9514 1404 393

Answer:

  C  24

  D  25

Step-by-step explanation:

Consider the choices offered:

  5 and 7 will not form a triangle* with any of the other lengths

  7 and 12 will not form a triangle with any of the other (longer) lengths

  7 and 24 will form a triangle with the other possibilities, 25 and 29. (needs further consideration)

  7 and 25 will not form a right triangle with 29, because a right triangle cannot have 3 odd-length sides.

__

<em>Further consideration</em>

  7^2 +24^2 = 49 +576 = 625 = 25^2 . . . . checking Pythagorean theorem

The side measures 7, 24, 25 will form a right triangle.

_____

* A triangle can be formed from three segments only if the sum of the shortest two exceeds the length of the longest one.
