Answer:
$13.79
Step-by-step explanation:
13.13x0.05=0.6565
Tax=0.66
13.13+0.66=13.79
Answer:
The answer is 30°
Step-by-step explanation:

An arithmetic sequence starts with one number and you add the common difference to the previous term to get the current term
So...
f(x)=mx+b
m=common difference
b=starting point
f(11)=125=11m+b
-
f(1)=5=1m+b
--------
120=10m
Divide both sides by 10
12=m
Your common difference is 12.
It is already in radical form......... but, if you want us to make it into exponential form, it is 8x^(2/3)
So for the first 8, we need to find the value. The way I would find the value would be to find it's place value. So I know that the 8 is in the millionths period. So the value of the eight would be in the millionths. So I think it would be 8,000,000. So that would be the answer. The 8's value is 8,000,000 because of it being in the millionths period.
Hope that helped! :D
