For this distance-time graph, what is the velocity of the car? 8500 m/s 3.3 m/s 50 s 170 m

Vel. of the car = 3.33 meter per second.

Explanation:

In given graph, y axis represent the distance traveled by the car and x axis represent the time taken by car.

At time t = 30 seconds , distance traveled by the car is 100 meter

We know that,

Speed =

speed =

speed  = 3.33 meter per second

That's the final answer.

I hope it wil help you.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
