A is 23 and the answer to b is 77
Answer:
see explanation
Step-by-step explanation:
Given
2cosΘ - 
= 0 ( add to both sides )
2cosΘ = ( divide both sides by 2 )
cosΘ = 
Since cosΘ > 0 then Θ is in first and fourth quadrants, hence
Θ = 
( ) = 
OR
Θ = 2π - = 
solutions are Θ = ,
The interval of the function that contains the local maximum is given by:
[0, 2].
<h3>What is the question?</h3>
The graph of the function that we want to analyze the behavior is missing. It states that:
- The function is decreasing from negative infinity to x = -0.8.
- Then the function increases from x = -0.8 to x = 1.55.
- After that, the function decreases until infinity.
<h3>What is a local maximum in a function f(x)?</h3>
A local maximum in a function f(x) is a value of x at which the function changes from increasing to decreasing.
Researching this problem on the internet, and looking at the graph, the function changes from increasing to decreasing at point x = 1.55, hence the interval that contains the local maximum of the function is:
[0, 2].
