26 total letters, 10 total digits
with repeated letters/numbers:
26 * 26 *26 * 10* 10*10 = 17,576,000 ways
without repeats:
26 *25*24 *10 *9*8 = 11,232,000 ways
Answer:
1.5 + 10^8.
Step-by-step explanation:
(3 x 10^2) x (5 x 10^5)
= 3 x 5 * 10^2 x 10^5
= 15 x 10^(2 + 5)
= 15 x 10^7
= 1.5 + 10^8.
Yo sup??
From Newton's 2nd law of motion
F*t=Δp
=mv-mu
mu=0.4*15
=6
t=0.2
mv=0
Therefore
F*0.2=6
F=30 N
Hope this helps.
