Answer:
c
Step-by-step explanation:
1 + tan²theta = sec²theta
tan²theta = 3² - 1
tan²theta = 8
tan theta = sqrt(8)
Positive because Quadrant 1
sqrt(8) = sqrt(4×2) = sqrt(4)×sqrt(2)
= 2×sqrt(2)

Answer:
=
with T₁ = 5000
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence, that is
r =
=
=
= 
This indicates the sequence is geometric with recursive rule
= r 
Here tr =
, thus
=
, T₁ = 5000
