Answer: c
Step-by-step explanation:
notice... the dog's pen perimeter, does not include the side that's bordering the garden's, since that side will use the heavy duty fence, instead of the light one
so, the sum of both of those costs, will be the C(x)
so, just take the derivative of it, and set it to 0 to find the extremas, and do a first-derivative test for any minimum
- Domain:<u> List of x-values that are possible on a line</u>
- Range: <u>List of y-values that are possible on a line</u>
- Interval Notation: <u>Notation that represents the interval using the endpoints.</u> Brackets mean that the endpoint is included, parentheses means that it isn't. (e.g: (20,27] . 20 isn't included in the interval, 27 is.)
- Additional Note: <u>Open circles mean that the point is excluded, closed circles mean that the point is included.</u>
Firstly, let's look at the domain. We see an open circle at x = -6 and a closed circle at x = -1, then an open circle at x = 1 and a closed circle at x = 5. Using what we know, this means that <u>the domain is </u>
Next, let's look at the range. We see an open circle at y = -3 and a closed circle at y = 2, then we see a closed circle at y = 3 and an open circle at y = 7. Using what we know, this means that <u>the range is </u>
Divide 101 with 500
101/500 = 0.202
0.202 is your decimal equivalent.
hope this helps
