A particle moves along the x-axis at any time t is greater than or equal to 0, its position is given by x(t)=t^2-6t^2+9t-2 where x is meters and t is in seconds a.find v(t) the velocity of the particle at time t
b.for what values of t greater than or equal to 0 is the particle moving to the right?
c.find the acceleration when the particle changes direction from moving right to moving left
d.at what time is the acceleration 24m/s^2
e. is the particle speeding up or slowing down or neither at t=0? give a reason for your answer
f. find the total distance the particle has traveled when t=4 seconds

Yes

Step-by-step explanation:

So I'll assume that x3 is 3x -->

so 3x • 3x • 3x =? to 3x • 3 • 3?

You can first simplify this to 3^3x =? to 3x • 9 -->

27x =? to 3x • 9 => so there are many solutions but if per say x = 5 then yes it would be equal.

Check with another number per instance 8

27(8) = 216 => 24(9) = 126

Yes they are equal

Hope this helps!
