Answer:
the radius would be half of 45 so if you half it i think it would be 22.5 but someone correct me if im wrong
Step-by-step explanation:
have a good day
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.
144. The square root of 144 is 12 because 12 x 12 = 144.
The segment goes from point (-1, 3) to (1,-1)
Slope = rise / run = (-3 - 1) / (1 - (-1)) = -4 / 2 = -2
Slope = -2
C = 2 pi r
C = 2(13) pi
C = 26 pi
