The velocity of a particle can be modeled by the function v(t)=1/10 (3t-8)^3+2 graph it

v (t) = 1/10 (3t-8) ^ 3 + 2
 For this case, what you should keep in mind is that you can use any computational tool to graph this function.
 You can use for example excel, or wolfram alpha.
 Just keep in mind that:
 Dependent variable: v (t)
 Independent variable: t
  
 See attached image for the graphic.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

11/36 is .305 repeating
