Adding odd numbers: make a conjecture about the sum
j=0 (2j+1)=1+3+5+7++(2n+1)
prove it by induction.
**very confused because everywhere i have looked it (2n-1) is there any way to solve

for the points

step-by-step explanation:

60%

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

faster, im not sure why but i know it is faster
