Answer:
Step-by-step explanation:
pythagoras theorem
a^2+b^2=c^2
8^2+x^2=10^2
64+x^2=100
x^2=100-64
x=
x=6 km
Answer:
π^2, 9.8 repeating, square root of 99.
Step-by-step explanation:
Answer:
210.
Step-by-step explanation:
Combination formula is

Then, we have that n = 10 and r=6:


To simplify calculus, we are going to use that n! = (n-1)!n = (n-2)!(n-1)n and so on.





I don't know the options but I guess it would be something like this:
40,000 < x < 50,000
