They created ratios so people could get information.
Answer:
a) we know that this is convergent.
b) we know that this might not converge.
Step-by-step explanation:
Given the 
is convergent
Therefore,
(a) 
The power series 
has radius of convergence at least as big as 8. So we definitely know it converges for all x satisfying -8<x≤8. In particular for x = -3
∴ is convergent.
(b) 
-8 could be right on the edge of the interval of convergence, and so might not converge
Answer:
The first choice.
Step-by-step explanation:
There are no real square roots of numbers < 0
so the domian is all real numbers greater than or equal to zero.
Answer:
about 28
Step-by-step explanation:
its actually 27.8125 but if we're estimating im assuming that means to round
If the rate is 60 pounds for $6.60 and we need to convert it to a unit rate per ounce, you will think of it as $6.60 for 60 pounds instead.
Divide to get a unit rate per pound.
$0.11 per pound
To convert this to an amount per ounce Change the rate to say $0.11 per 16 ounces(this means the same).
Divide 0.11 by 16 to get 0.006875 or $0.007 or 0.7 cents per ounce. Choice D but it should say per ounce, not per pound.
