Answer:

288J

Step-by-step explanation:

recall the formula for kinetic energy

KE = (1/2) mv²

where m is the mass (= 4kg)  and v is the velocity(=12 m/s)

hence

KE = (1/2) (4)(12)² = 288J

Answer: 288 Joules

Step-by-step explanation:

K.E = 1/2* mass * square of the velocity

K.E = 1/2 * m * v ^ 2

From the question:

Mass = 4kg

Velocity = 12m/s

Therefore:

K.E = 1/2 * 4 * 12^ 2

= 0.5 * 4 * 144

= 288 Joules

Which sample fairly represents the population? Select two options.
ExtremeBDS [4]

Answer:

b) observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses.

d) taking a poll in the lunch room (where all students currently have to eat lunch) to determine the number of students who want to be able to leave campus during lunch.

Step-by-step explanation:

These are the two options that are most likely to give you a sample that fairly represents the population. In the first case, the sample that you obtain is likely to be a good representation because Main Street is a road where a great variety of people walk. Moreover, 5 pm is also a time that will allow you to see  a great number of different people. The second answer will also give you a good sample, as the poll would include all students in the lunch room, which is all students in the school (the whole population).

How you would convert the repeating, nonterminating decimal to a fraction? Explain the process as you solve the problem.
bixtya [17]

Answer:

x = 0.1515...

100 x = 15.1515...

100 x - x = 15.1515... - 0.1515...

99 x = 15

x = 15 / 99 = 3 ∙ 5 / 3 ∙ 33 = 5 / 33

0.1515... = 5 / 33
