Answer:
7
Step-by-step explanation:
Substitution then simplify
I'd say it is A but I think you have made a tpyo
It should be 2*PI*radius^2 + 2*PI*radius*height
Answer:
Option B.
all real numbers
Step-by-step explanation:
We have
and 
They ask us to find
(fog)(x) and it's Domain
To solve this problem we must introduce the function g(x) within the function f(x)
That is, we must do f(g(x)).
So, we have:


Then:

The domain of the function f(g(x)) is the range of the function
.
Since the domain and range of g(x) are all real numbers then the domain of f(g(x)) are all real numbers
Therefore the correct answer is the option b: 
And his domain is all real.
Answer:

Step-by-step explanation:
we know that
The equation of the line into point slope-form is equal to

in this problem we have


substitute the values in the formula

Answer:
depends on the options
Step-by-step explanation:
a parallel line would be y = 1/2x + b, where b is any number
