Answer:
Step-by-step explanation:
Given is a differential equation of III order,

The characteristic equation would be cubic as

By trial and error, we find that

Thus m=2 is one solution
Since given that
is one solution we get
m = -4+i and hence other root is conjugate 
Hence general solution would be

From my knowledge, I think it is 9
2+number won over 9+number played=1/2
number won=number played (number played means how many more past 9)
so
if n=number won=number played then

times both sides by (2)(9+n)
2(2+n)=9+n
distribute
4+2n=9+n
minus n from both sides
4+n=9
minus 4 from both sides
n=5
answer is 5
test
2+5=7
9+5=14
7/14=1/2
true
n=5

Answer:
42
Step-by-step explanation:
You can find the product of two numbers by adding them. The question says what is the product of the 6th and 2nd square numbers. The first ten square numbers are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 so the second square number is 4 and the 6th square number is 36 and 36 + 4 is 42. Hope this helped! Stay safe!
