The first digit can be any one of the numbers 2-9 That a total of 8 numbers.
The next 6 digits can be any permutation of 6 from the numbers 0 to 9.
(10 numbers)
nPr = n! / r!
so here we have 10P6 = 10! / 6! = 10*9*8*7 = 5040
So final answer is 8 * 5040 = 40,320
Answer:
1
Step-by-step explanation:
For a:
(2400*2*PI)/60(seconds) = 80 PI RAD/Sec
For b:
arc length s= radius r * central angle(in radians)
= ((80*pi*7.5)/(2*pi)
=25
