Answer:
+120/169 or -120/169
Step-by-step explanation:
- let
where, alpha is some angle that satisfies the assumed condition.
- so,
[ taking cos to the other side or applying cos on both sides]
- now, substitute this in the given expression
as sin =
[by general trigonometry formula: ]
so if , we can get sin from the above formula as + or - 12/13
(because, after taking square root on both sides we keep + or -]
- as, sin
[by general trigonometry formula]
- here, now
so, the final value can be 120/169 or -120/169.

Answer:
5x4
Step-by-step explanation:
5x4=20
The formula for this question is P(n) = P*(1+r)^n
So the initial population is 8600 or P, and n can be the number of years. r is the rate it grows, 3% or 0.03.
Plug in these values
P = 8600
r = 0.03
n = 3
into P(n) = P*(1+r)^n
That is the correct standard form as its is
