Answer:
r = 3.95 ft
Step-by-step explanation:
Volume of cone =
= 246 ft³
246 = 
r² = 
r = 
r = 3.95 ft
Correct Answer:
Option A
Solution:
f(x) = 7x + 9
g(x) = 7x - 4
We can re-write g(x) as:
g(x) = 7x + 9 - 13
Since 7x+9 is equal to f(x), we can write:
g(x) = f(x) - 13
This relation shows that g(x) is obtained by shifting f(x) 13 units vertically down. So the correct answer is option A.
Answer:
The solution is 
Step-by-step explanation:
To solve this exponential equation, we must write both sides as powers of 3.
The equation given is:

Since
, we have that
, so
Then




Since both sides are now powers of 3, we can equal them:




The solution is
