Option A
<em><u>Solution:</u></em>
Given that we have to rewrite with only sin x and cos x
Given is cos 3x
We know that,
Therefore,
---- eqn 1
We know that,
Substituting these values in eqn 1
-------- eqn 2
We know that,
Applying this in above eqn 2, we get
Therefore,
Option A is correct

Answer:
x=-21/47
Step-by-step explanation:
The population of the fish is given by P(t) = 750(1 + 0.083)^t; where t is the number of years after 2005.
Here, t = 2050 - 2005 = 45
Population in 2050 = 750(1.083)^45 = 750(36.16) = 27,123
