9! = 9*8*7*6*5*4*3*2*1 = 362880
10*9*8 = 720
How many different ways can we arrange 9 objects taken 3 at a time?
Permutations are the different arrangements of any number of objects. When we arrange some objects in different orders, we obtain different permutations.Therefore, you can't say "What is the permutation of 5?". To calculate permutations, one has to get the following details:The total number of objects (n) (necessary)The number of objects taken at a time (r) (necessary)Any special conditions mentioned in the question (optional).

Do a web search for "permutations and combinations" to find the how. I make it 35,960.
8*7/(2*1) = 28
10*9*8 = 720
How many different ways can we arrange 9 objects taken 3 at a time?
Combinations from 90 objects, taken 3 at a time is 90C3 = 90*89*88/(3*2*1) = 117,480.
The Time We Have Taken has 327 pages.
if the objects distance travelled and time is given then speed=distance/time eg- distance travelled 50 mtrs time taken 5 seconds speed 50/5 =10m/s velocity=u(initial velocity 0 for free falling objects) + at(acceleration x time)
Distance covered between two points in unit time. eg : distance between A and B /time taken =distance/time
The speed of an object can be found by dividing the distance travelled by the object by the time taken for the object to travel that distance. Speed=Distance/Time
You can not select many objects at the same time when system variable "pickadd" is turned off. If you select a new object, previously selected objects will be canceled. When system variable "pickadd" is turned on you can select many objects at the same time. There are two ways to turn "pickadd" on. One is to press button on property box another is to input "pickadd" in command line then input "on"
Galileo dropped two different sized objects from the tower of Pisa and they both hit the ground at the same time. The object was to prove that the size/weight (i.e. mass) of the object would not affect the rate of fall.

Echolocation is the ability to locate objects by bouncing sound waves off of them, and then measuring the time taken for an echo to return and calculating the direction the echo came from.
