Answer:

v = u + at \\ v = 2 + ( - 5)( \frac{1}{2} ) \\ v = 2  + \frac{( - 5)}{2}  \\ v =  \frac{4 + ( - 5)}{2}  \\ v =  \frac{ (- 1)}{2}  \\ v =  - 0.5 \: m {s}^{ - 1}

<h3><em><u>-0.5 m/s</u></em> is the right answer.</h3>

It will cost Amber an estimated $3,723 a year in tuition to attend her preferred college. She has been putting $350 a month in a
kenny6666 [7]

Answer:

Yes; she will have $4008 for other expenses.

Step-by-step explanation:

First you find out how much she saved by multiplying 350 by 36 as she saved for 3 years which is 36 months.

350 \times 36 = 12600

After that you need to work out the amount she needs in total for her tuition by multiplying 4 by 3723 which is the amount needed per year.

3723 \times 4 = 14892

If her parents add to her account half the amount she saved that means that they give her an additional 6300 as that's half of 12600.

This means she has 18900 and if you take away 14892 you will be left with 4008 for expenses.

Determine how long it will take an object to rotate through 6.9 revolutions at an angular velocity of 3.1 radians per second. Us
gregori [183]

Answer: 13 . 99 seconds

Step-by-step explanation:

The formula to find how long it will take an object to rotate through 6.9 revolutions at an angular velocity is given as :

t = 2π x number of revolutions / angular velocity

Therefore :

t = 2π x 6.9 / 3.1

t = 2 x 3.142 x 6.9 / 3.1

t = 43.3596/3.1

t = 13. 98696774194

to the nearest tenth

t = 13. 99s
