Answer:
A.
Step-by-step explanation:
We have been given that f be a differentiable function such that, , , and . The function g is differentiable and for all x.
We know that when one function is inverse of other function, so:
Upon taking derivative of both sides of our equation, we will get:
Plugging into our equation, we will get:
Since , then .
Since we have been given that , so we will get:
Therefore, and option A is the correct choice.

Answer:
The height is 11/2
Step-by-step explanation:
We know SA = 30n
and r = 2
We are solving for h. So plug in our values
30n = 2n(2)^2 + 2n(2)h
Multiply and square on the right side terms
30n = 8n + 4nh
Divide everything by n
30 = 8 + 4h
Subtract 8 on both sides
22 = 4h
Divide by 4 on both sides
h = 22/4 = 11/2
Check:
30n = 2n(2)^2 + 2n(2)(11/2)
30n = 8n + 22n
30n = 30n
Answer:
B/ x=4
Step-by-step explanation:
Just take 2x to another side to be neg-, the same thing with 4 , then divide it both sides by 4 to get the answer.
