Answer:
The given statement is true.
Step-by-step explanation:
The graph of the inverse function is reflection about the line y = x from the graph of the function.
Apart from these the domain of the inverse function is the range of the function and the range of the inverse function is the domain of the function.
Let us graph the functions and
The exponential function always passes through the point (0,1) and logarithm function passes through the point (1,0).
From the graph we can see that the graph of exponential function is the reflection about the line y=x.
Hence, exponential function is the inverse of a logarithmic function.
Thus, the given statement is true.

Answer:
<h2>1. V = 100 in³</h2><h2>2. h = 10 in</h2>Step-by-step explanation:
The formula of a volume of a cylinder:
<em>B</em><em> - base area</em>
<em>h</em><em> - height</em>
<em />
1. We have
<em>h = 5in, B = 20 in²</em>.
Substitute:
2. We have
<em>B = 20.7 in², V = 207 in³</em>.
Substitute:
<em>divide both sides by 20.7</em>
