thank you very much
probably...x=−99+√8021,c=0
...I give up
thhhhx
5%=0.05
so each year, it multiplies by 0.05.
And since is ten years. You just have to calculate 0.05^10
The anwser is 1, 1*4-3=1^2 and 1*7-3=2^2
Also, please help with this:
I choose three different numbers out of this list and add them together: 1, 3, 5, 7, 9,..., 105. How many different totals can I get?
the anwser should not repeat, for example 105+1+3 and 103+1+5 have the same anwser.
ps: I think that anwser is 150, can anyone check?
