Answer:
Option D
Step-by-step explanation:
f(x) =
Transformed form of the function 'f' is 'g'.
g(x) = ![\frac{1}{2}\text{log}_{15}(x+4)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctext%7Blog%7D_%7B15%7D%28x%2B4%29)
Property of vertical stretch or compression of a function,
k(x) = x
Transformed function → m(x) = kx
Here, k = scale factor
1). If k > 1, function is vertically stretched.
2). If 0 < k < 1, function is vertically compressed.
From the given functions, k = ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Since, k is between 0 and
, function f(x) is vertically compressed by a scale factor
.
g(x) = f(x + 4) represents a shift of function 'f' by 4 units left.
g(x) = f(x - 4) represents a shift of function 'f' by 4 units right.
g(x) = ![\frac{1}{2}\text{log}_{15}(x+4)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctext%7Blog%7D_%7B15%7D%28x%2B4%29)
Therefore, function f(x) has been shifted by 4 units left to form image function g(x).
Option D is the answer.
Answer:
r = 5
Step-by-step explanation:
The formula for volume of a cone is ![\pi r^2*\frac{h}{3}](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%2A%5Cfrac%7Bh%7D%7B3%7D)
h = 6
V = 50π
![2\pi r^2=50\pi](https://tex.z-dn.net/?f=2%5Cpi%20r%5E2%3D50%5Cpi)
r = 5
The answer is X= 5. Using the pythagorean theorem, and assuming that "b" is 3, half of 6 because the triangle is isosceles, you can solve the problem.
-5 is for f(x)=x+5
4 is for g(x)=x-4
Hope this helps!!
