Answer:
The value of g(a) is:
- g(a) = 3 - 2a
Step-by-step explanation:
Given
As the function g(x) is given by
To determine
g(a) = ?
In order to determine g(a),
substitute x = a in the function g(x) = 3 - 2x
g(x) = 3 - 2x
g(a) = 3 - 2(a)
g(a) = 3 - 2a
Therefore, the value of g(a) is:
- g(a) = 3 - 2a
<h3>Answer: Choice H) 2</h3>
=============================================
Explanation:
Recall that the pythagorean trig identity is
If we were to isolate sine, then,
We don't have to worry about the plus minus because sine is positive when 0 < x < pi/2.
Through similar calculations,
Cosine is also positive in this quadrant.
-------------
So,
Therefore,
is an identity as long as 0 < x < pi/2
