Move 4 to the left of f = 4f

which of the following expressions is the definition of the derivative of f(x)=ln(x) at the point (5,ln5)
Doss [256]
The definition of the derivative is
\frac{f(x + h) - f(x)}{h}
as h goes to 0. So since the f is ln(x)

\frac{ln(x+h)-ln(x)}{h}

Since it is evaluated at 5 (the point 5, ln5), it is

\frac{ln(5+h)-ln(5)}{h}

Two trains leave stations 456 miles apart at the same time and travel toward each other. One train travels at 105 miles per hour
love history [14]

Answer:

let x=distance 105 mph train traveled

(456-x)=distance 85 mph train traveled

Travel time = distance/speed (equal in both directions)

 

x/105=(456-x)/85

85x=105*456-105x

190x=105*456

x=105*456/190=252 miles

travel time=252/105=2.4 hrs

ans:

The two trains will meet in 2.4 hrs
