A body moves s metres in a time t seconds so that s = t3 – 3t2 + 8. Find:
aleksandr82 [10.1K]

Answer is<em> </em><em><u>3t²-6t</u></em>

<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, <u>v(t) = 3t²-6t</u>

Which classification describes the following system of equations?
wolverine [178]

A consistent and independent system of equations describes the given system of equations.

The consistent and independent system of equations are given below.

  • 12x+5y-3z= 36
  • x-2y+4z=3
  • 9x-10y+5z = 27

<h3>What is a consistent independent equation?</h3>

A consistent equation is a system of linear equations that is consistently unbiased when it has precisely one solution. While this is the case, the graphs of the lines within the system move at exactly one point. In inconsistent, a system of linear equations is inconsistent if it has no solutions.

Hello from MrBillDoesMath!

Answer:

The side length is at most 7 inches.

Discussion:

A regular hexagon is a 6-sided polygon where the length of each  side is the same. Let this length be L. Then the problem states that 6L < 42, so L < 7
