Answer:
(3, 6)
Step-by-step explanation:
If you create a mini graph, like I did, you would have seen that the middle point is at the co-ordinates (3,6). I have attached a image to this reply, with my "graph". (Sorry if its a little ugly, but that doesn't matter, the math does.)
The answer will be 8.39 because the third number (8) is above 5 so you have to round up. Good luck!
Answer:uh
Step-by-step explanation:
To calculate the relative vector of B we have to:
![P_B=\left[\begin{array}{ccc}3\\3\\-2\\3/2\end{array}\right]](https://tex.z-dn.net/?f=P_B%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%5C%5C3%5C%5C-2%5C%5C3%2F2%5Cend%7Barray%7D%5Cright%5D)
The coordenates of:
, with respect to B satisfy:
![C_1(1)+C_2(2t)+C_3(-2+4t^2)+C_4(-12t+8t^3)= 7-12t-8t^2+12t^3](https://tex.z-dn.net/?f=C_1%281%29%2BC_2%282t%29%2BC_3%28-2%2B4t%5E2%29%2BC_4%28-12t%2B8t%5E3%29%3D%207-12t-8t%5E2%2B12t%5E3)
Equating coefficients of like powers of t produces the system of equation:
![\left \{ {C_1-2C_3=7} \atop {2C_2-12C_4=-12} \right. \\\left \{ {{4C_3=-8} \atop {8C_4=12}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7BC_1-2C_3%3D7%7D%20%5Catop%20%7B2C_2-12C_4%3D-12%7D%20%5Cright.%20%5C%5C%5Cleft%20%5C%7B%20%7B%7B4C_3%3D-8%7D%20%5Catop%20%7B8C_4%3D12%7D%7D%20%5Cright.)
After solving this system, we have to:
![C_1=3\\C_2= 3\\C_3= -2\\C_4= \frac{3}{2}](https://tex.z-dn.net/?f=C_1%3D3%5C%5CC_2%3D%203%5C%5CC_3%3D%20-2%5C%5CC_4%3D%20%5Cfrac%7B3%7D%7B2%7D)
And the result is:
![P_B=\left[\begin{array}{ccc}3\\3\\-2\\3/2\end{array}\right]](https://tex.z-dn.net/?f=P_B%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%5C%5C3%5C%5C-2%5C%5C3%2F2%5Cend%7Barray%7D%5Cright%5D)
