Answer:
A. 
Step-by-step explanation:
We are given the functions f(x) and g(x) as,


It is required to find the function ( f+g ) i.e. ( f+g ) (x)
So, 
i.e. 
Hence, we get that
.
So, the first option is correct.
The slope is the number in front of the x. In this equation it is 1.
Answer:true
Step-by-step explanation:
Apex
Answer:
3.5 m
Step-by-step explanation:
Use Pythagorean theorem to find the distance (d) the distance goes up the wall = adjacent to the angle 75° that is formed with the wall.
Length of ladder = the hypothenuse = 13.5 m
Thus, we would use:
Cos75 = adjacent/hypothenuse
Cos 75 = d/13.5
Multiply both sides by 13.5
13.5*cos(75) = d
13.5*0.2588 = d
3.4938 = d
d ≈ 3.5 m (nearest tenth)
All but B, as on B an a can be factored out
