A body moves s metres in a time t seconds so that s = t3 – 3t2 + 8. Find:
Lady bird [3.3K]

Using derivatives, it is found that:

i) v(t) = 3t^2 - 6t

ii) 9 m/s.

iii) a(t) = 6t - 6

iv) 6 m/s².

v) 1 second.

<h3>What is the role of derivatives in the relation between acceleration, velocity and position?</h3>
  • The velocity is the derivative of the position.
  • The acceleration is the derivative of the velocity.

In this problem, the position is:

s(t) = t^3 - 3t^2 + 8

item i:

Velocity is the <u>derivative of the position</u>, hence:

v(t) = 3t^2 - 6t

Item ii:

v(3) = 3(3)^2 - 6(3) = 27 - 18 = 9

The speed is of 9 m/s.

Item iii:

Derivative of the velocity, hence:

a(t) = 6t - 6

Item iv:

a(2) = 6(2) - 6 = 6

The acceleration is of 6 m/s².

Item v:

t for which a(t) = 0, hence:

6t - 6 = 0

6t = 6

t = \frac{6}{6}

t = 1

Hence 1 second.

What is -1.2 times 1 1/5 divided by 3/10
djyliett [7]

I think it would be easier to covert the fractions to decimals here

-1.2 * 1 1/5 / 3/10

= -1.2 * 1.2 / 0.3

= -1.44 / 0.3

= - 4.8 answer

What percent is the change in the price if: a The price was $100 and now it is $1250?
KatRina [158]

Answer:

The increase is 1150.

11.5 times the original value, or 1150% of it. That's a big increase, and I would not buy that thing, whatever it is.

PLZ ANSWER THIS ITS DUE TODAY I WILL GIVE BRAINLEST!!!!
Sever21 [200]

Answer:

In many instances, the lyrics to folk songs came from existing nursery rhymes or poems, and some of the nursery rhymes had variations, depending on region or time. Thus, these folk songs may have lyrics that are slightly different from those you are familiar with.

Therefore, in my opinion, I think that Nursery songs can be considered folk music.

Im so so so so sorry if this is wrong or not the answer you were looking for. i truly am. hopefully this will be good
