Amy purchased a brand–new mountain bike, which she's riding through the winding trails. The bike's displacement is given by s(t) = t3 − 2t2 + 3. What is the bike's acceleration after three minutes?

a = 14 m/min²

Step-by-step explanation:

The displacement of bike is given by :

Velocity,

Finding velocity of the bike.

Acceleration,

At t = 3 minutes,

a = 6(3) - 4

= 18-4

= 14 m/min²

So, the bike's acceleration after 3 minutes is 14 m/min².

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..
