Answer:
Step-by-step explanation:
We are given the graph of the function:
And we want to determine its real and complex roots.
First, notice that it crosses through the x-axis at 3. This means that (x-3) is a factor.
Hence, let's use synthetic division to factor. This yields:
3 | 1 -1 -4 -6
|_______(3)___(6)___(6)_________________
1 2 2 0
Therefore,this yields:
The right-most term is not factorable. Thus, we will need to use the quadratic formula.
Zero Product Property:
We will use the quadratic formula on the right. Our a=1, b=2, and c=2. Therefore:
Evaluate:
Simplify:
Hence, our solutions are:

Answer:
C. The radius is 16 feet and the area is 804 square feet
Step-by-step explanation:
In A, it doesn't use the correct unit because it is supposed to say 804 feet square. In B, the diameter would be 50 I think, and again it doesn't say feet square for area. In C, the radius is 16 feet and the area is 804 square feet, so that is correct. In D, it says the diameter is 16 feet, but it had the correct area.
