Given:
Roots:
![\begin{gathered} -3+\sqrt[]{6} \\ -3-\sqrt[]{6} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20-3%2B%5Csqrt%5B%5D%7B6%7D%20%5C%5C%20-3-%5Csqrt%5B%5D%7B6%7D%20%5Cend%7Bgathered%7D)
Point: (-1,4)
To determine the equation of the parabola with the given roots and point, we find the missing values first.
Since the roots are given, we can say that the equation is:
![y=a(x+3-\sqrt[]{6})(x+3+\sqrt[]{6})](https://tex.z-dn.net/?f=y%3Da%28x%2B3-%5Csqrt%5B%5D%7B6%7D%29%28x%2B3%2B%5Csqrt%5B%5D%7B6%7D%29)
Next, we expand the terms.

Then, we plug in x= -1, and y=4 into the equation to get the value of a.

So,
it isn't lined up to x straight while it's crooked
Answer:
6 boats
Step-by-step explanation:
Consider this, there are 10 boats from South Carolina and 10 from other sates.
So, lets make ratio with is 1/1 because for every 1 boat from other states, there is 1 boat for South Carolina.
There are 12 boats, divide them evenly to get the answer of 6 boats from South Carolina. The reason for dividing by two was due to the fact that half for South Carolina and half from other states. Now there is your answer.
