Its factors would be
(x+2)*(x-1)*(x+0)

x^2 +x -2

x^3 + 0 + x^2 + 0 -2x +0

Equation: x^3 + x^2 -2x
f(2) = 8 + 4 -4

2x^3  + 2x^2  -4x +0
f(2) = 16 + 8 -8

3x^3  + 3x^2  -6x +0
f(2) =  24 +12 -12

4x^3  + 4x^2  -8x +0
f(2) =  32 +16 -16

So, the equation is:
4x^3  + 4x^2  -8x = 0

Which scenario could be represented by the given graph?
Alex Ar [27]

Answer:

Choice D

Step-by-step explanation:

The distance increases at a steady rate from time = 0 to time = 1.

Then no progress is made between time  = 1 and time = 2.

Then the distance increases at the same steady rate from time =2 to time = 3.

Finally, no progress is made between time = 3 and the end of the graph.

Eliminate Choices A, B and C immediately, because none of these scenarios involves a stop and wait.

That leaves only Choice D as a reasonable verbal description of what's happening here.

Which list shows these lengths in order from greatest to least?
finlep [7]

9514 1404 393

Answer:

  √3/11, π/24, 3/25, 9/100

Step-by-step explanation:

The 2-decimal value of each of the numbers is ...

  9/100 = 0.09

  π/24 = 0.13

  3/25 = 0.12

  √3/11 = 0.16

Then the order from greatest to least is 0.16, 0.13, 0.12, 0.09. In the original form, that is ...

  √3/11, π/24, 3/25, 9/100 . . . . . matches choice B
