Using the following graph, explain the behavior of function f on the interval from
x = 0 to x = 10.

State over which intervals f is increasing or decreasing and concave up or concave down. (Enter your answers using interval notation. If an answer does not exist, enter DNE.)

I JUST WANT TO CONVERT 10.2 m/s to km/h.

But Textbook solution is like this :

10.2 x 1m/1s x 1km/1000m x 60s/1 min x 60min/1h =36.7km/h


Is there another way of converting or can u plz explain the above steps in detail...plz help me..this question is basically in physics book...

if y= e^ax cos^3 x sin^2 x find dy/dx

show that the length of the curve y = log Sec x between the points x = 0 and x = pi/3 is log(2 + √3)
