You can do $42.25 divided by 6.5 = x or x times 6.5 = $42.25
Answer:
<em>Thus the domain is the real numbers and the range is y>3.</em>
<em>Answer: Option C)</em>
Step-by-step explanation:
<u>Domain and Range of Functions</u>
To determine the domain and range of a function given on a graph, we use the vertical and horizontal line methods respectively.
The domain consists of all the values of x for which the function exists. We are told that the function is an exponential decay. Exponential functions without specified restrictions have a domain of all the real numbers.
Imagine a vertical line moving from minus infinite x to plus infinite. The line would always cross the graph at one point, thus the domain is all the real numbers.
Now for the range, imagine a horizontal line coming from y minus infinite. It won't get in contact with the graph until it approaches y=3. Once it goes up y=3, the line touches the graph in one point up to infinity y. The range is y>3.
Thus the domain is the real numbers and the range is y>3.

Answer:
The volume of the frustum is:
which corresponds to the third answer shown in the list of options
Step-by-step explanation:
The image can be interpreted as an original tall cone of height 6.4 plus 6.8 (13.2) that was divided into two parts by chopping the smaller upper cone, and leaving the frustum (the volume of which we need to find). So, to estimate the volume of this frustum, knowing the general formula for the volume of a cone:
(where B is the area of the cone's base, and h its height)
we could calculate the volume of the larger cone, and subtract from it the volume of the upper smaller one.
For the area of the cone's base, recall call also that the area of a circle of radius R is given by: , and therefore the formula for the volume of the cone can be written as:
So, now the volume of the larger cone is:
The volume of the smaller cone:
Therefore, the difference becomes:
This is the volume of the frustum:
