A body moves s metres in a time t seconds so that s = t3 – 3t2 + 8. Find:

aleksandr82 [10.1K]

Answer is 3t²-6t

<h3>Step-by-step Explanation:-</h3>

$s(t) = {t}^{3} - 3 {t}^{2} + 8$

Now we need to find velocity. The velocity is the first derivative of position, so let's find the derivative of s(t) :-

$s'(t) = v(t) = 3 {t}^{3 - 1} - 3 \times 2 {t}^{2 - 1}$

So,

$v(t) = 3 {t}^{2} - 6t$

Therefore, v(t) = 3t²-6t

Can I get some help on number 23 ? :/

We're looking for the volume, since it's trying to find out the cost for filling the entire box.
We have our length, width, and height.
8, 6, and 1.
We're multiplying 8, 6 1, and 0.3 since it is $0.3 per sq ft,
Our equation is:
0.3 (8x6x1) = x
8 x 6 x 1 = 48.
48 x 0.3 is 14.4
$14.4 is your answer
Hope this helps!
