Let g(x)=x^3+2x-5. By the Mean Value Theorem for Derivatives, there must a number c in (-1,2) such that g'(c) equals which value?

E. 5

Step-by-step explanation:

g(2) = 2³ + 2(2) - 5 = 7

g(-1) = (-1)³ + 2(-1) - 5 = -8

(-8 - 7)/(-1 - 2)

-15/-3

= 5

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
