Let f be a differentiable function with f(1)=3. The graph of f′, the derivative of f, is shown above. Which of the following statements is true about the line tangent to the graph of f at x=1 ?

idk

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

the answer is 8/21

hope this
