i have to questions that just need to be checked on to see if i got them right. Lim x-->infinity for both problems 10/x+10 is number one i got 0 for this one. or is it does not exist. lim x-->infinity 6x/6x+5 for this one I got One. (1) is that correct.??
easy cal Q
Thanks! Exactly what I was looking for.
easy cal Q
lim x--->a x^2+a^2/x+a I know this equals (a) but I dont know how to explain my answer.
physics
A) m*v^2=kinetic energy m*72^2=7.6*10^7 m*(7.6*10^7)/(72^2)=14660.5kg B) p=w/t p=(7.6*10^7)/2=3.8*10^7 p=38000000 watts
