Answer:

18, 36, 72, 144, 288, 576, 1152

Step-by-step explanation:

I might be wrong but I think that is the answer

You just keep adding

For example- 72+72=144

144+144=288

Answer: 288, 576, 1152

Step-by-step explanation: What you do here is that you multiply every number by two. You start by doing 18 times 2, which equals 36. Then you do 36 times 2, which equals 72. You keep on doing this until you get the answers needed.

Hope this helped!! :)

How to mathematically divide a circle into 60 parts with coordinates?
Naddika [18.5K]
The coordinates are (rcos(6n),rsin(6n)) where r is the radius of the circle and n ranges from 0 to 59.
60 parts gives the angle 360/60=6 degrees, so multiples of this angle (6n) determine the coordinates.
When n=0, the coords are (r,0); when n=5, the coords are (r√3/2,r/2); when n=10 the coords are (r/2,r√3/2), etc.

A number is called a "decreasing number" if each digit in the number is less than the digit to its left. For example, 87420 is a
Vera_Pavlovna [14]

Answer:

  252

Step-by-step explanation:

The question is fully equivalent to asking how many subsets of length 5 there are of 10 objects (digits 0–9). That number is 10C5, where nCk is the number of ways to choose k objects from a list of 10. The value of that is ...

  nCk = n!/(k!(n-k)!)

There are 252 ways to choose 5 numbers from the digits 0-9:

  10C5 = 10!/(5!(10-5)!) = 10·9·8·7·6/(5·4·3·2·1) = 9·4·7 = 252

_____

The order of the selection doesn't matter, because the selected digits are always arranged in decreasing order to form a decreasing number.
