Given :
To Find :
All real value solution of given equation.
Solution :
Simplifying given equation, we get :
sec x( sec x + 2 ) = 0
sec x = 0 and (sec x + 2) = 0
For, sec x = 0 :
x = not defined.
For, (sec x + 2) = 0 :
cos x = -1/2
x = cos⁻¹( -1/2 ) = 2π/3
Therefore, general solution is ( 2nπ ± 2π/3 ), n ∈ Z⁺ .
Answer:
Option d.
Step-by-step explanation:
It is given that Aarav has 3,250 followers on social media. His number of followers is increasing at a rate of 3% per week.
Initial followers = 3,250
Rate =
The exponential growth function is
where, a is initial value, r is rate and w is time per week.
Substitute a=3,250 and r=0.03.
Therefore, the correct option is d.
