7. Find the average rate of change for the function f(x) = 24x' - 36x - 528x – 1260 over-25x54.

The kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?

If y varies inversely with x and y=11 when x=3 find the equation that relates x and y.

Differentiate the function. dy dx y = (9x2 - 2) (8x2 - 2x+6) =

what is y=1/2tan3x
