Answer:
Domain:
Step-by-step explanation:
For a geometric sequence, the n-th term is given by:
From the question, and .
Hence the explicit formula for the sequence is:
, where
Therefore the domain is natural numbers or positive integers.
Answer:
F
D
Step-by-step explanation:
Tan(Θ)=(h/distance from base)
Θ=13 degrees, 1mile=5280 ft
tan(13)=(h/5280 ft)
5280tan(13)=h
h=1218.984049
h=1219 ft
It’s E because that’s basically 1/4
Answer:
If your investment dropped 7% and then increased by 8% you will not be a percent ahead. The reason being is that the increase is a lower amount and the decrease was on a larger amount.
For example, if you have $100 invested. 100*.07=$7, 100-7=$93 remaining. 93*08= $7.44. 93+7.44=100.44 (a .44 increase from the original number). One percent increase from the original number would have $101.
