AN C FOR 9
OpenStudy (jtvatsim):
I definitely agree with C for 9... I'm still thinking about 8.
OpenStudy (phebe):
OK GREAT!
OpenStudy (jtvatsim):
Do you have a calculator handy? If you do you can plug in sqrt(42) to see what that looks like.
OpenStudy (jtvatsim):

rational numbers are fractions... No way is sqrt(42) a fraction, it's decimals don't repeat.
OpenStudy (phebe):
yes i have a calculater
OpenStudy (jtvatsim):
Because it's decimals don't repeat it is an irrational number for sure.
OpenStudy (jtvatsim):
Whole numbers are like 1, 2, 3, 4, and have no decimals.... so no to that.
OpenStudy (jtvatsim):
Integers are just whole numbers that are 0 or negative too, so -2, -1, 0, 1, 2, ... so no

So, in other words, I think the answer is B. This is an irrational number because the decimals don't repeat.
OpenStudy (jtvatsim):
Yep, what a mess... definitely not a nice whole number, natural number, or integer.
OpenStudy (phebe):
so the answer is whut?
OpenStudy (jtvatsim):
It is an irrational number. B Irrationals have nonrepeating decimals.
