Answer:
2nd option
Step-by-step explanation:
Using the identities
tan²θ + 1 = sec²θ
cotθ = 
Given
secθ = - 
, then
tan²θ + 1 = (- )² = 
( subtract 1 from both sides )
tan²θ = 
( take the square root of both sides )
Since 
< θ < π and tanθ < 0 , then
tanθ = - 
Then
cotθ = 
= - 
Formula
V= c(1-r)^t
V= future value
C= current value
r= depreciation rate p/yr
t= number of periods
v = 20500*(1-0.16)^8
v =
Answer:
p1= 95, p2 = 180
Step-by-step explanation:
We have population : 50 given that population grows by 90% per year
So, After one year: new population (p1) will be
p1 = 50 + 50*0.9 = 50 + 45 = 95
Now, After two years: new population (p2) will be
p2 = 95 + 95*0.9 = 95 + 85.5 (approximately = 86) = 95 + 86 = 180
Therefore,
p1 = 95, and p2 = 180.
