WHAT IS COMBINED VARIATION?

what did you learn in the video? how do you differentiate combine variation from joint variation?

If t varies jointly with u and the square of v, and t is 1152 when u is 8 and v is 4, find t when u is 5 and v = 5.

y varies jointly as x and z and inversely as w, and y = 3/2, when x = 2, z =3 and w = 4. Find the equation of variation.

The amount of oil used by a ship traveling at a uniform speed varies jointly with the distance and the square of the speed. If the ship uses 200 barrel of oil in traveling 200 miles at 36 miles per hour, determine how many barrels of oil are used when the ship travels 30 miles at 18 miles per hour.
