Answer:
See below.
Step-by-step explanation:
When x has a value between 0 and 90 the values of sin x ranges from 0, if x = 0 and 1 , if x = 90 degrees.
The cosine of x has the reverse value: cos x is 1 for x = 0 and 0 for x = 90 degrees.
At x = 45 the sine and cosine are equal in value.
So for sin x < cos x the value of x must be between 0 and 45 degrees.
So a possible value of x is 30 degrees.
When x = 30 sin x = 0.5 and cos x = 0.866.

Step-by-step explanation:
Given the expression:

Using the distributive property: 

Simplify:

Simplify:

Therefore, the simplified given expression is, 
Answer:
f(2) = 2
Step-by-step explanation:
Substitute x=2 for x, but there is no x on the right side of the equation.
So since it is a straight line of f(x) =4, for any x, f(x)=2
Step-by-step explanation:
1. Pick two points on the line and use them to find the slope.
2. Then, find the coordinates of the y-intercept.
3. The y- coordinate is the value of b in the equation.
