Point A has coordinates (6,4) and point B has coordinates (2,7) write AB as column vector. Plz plz plz
Olenka [21]

Answer:

\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}

Step-by-step explanation:

<u>Column Vector</u>

Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.

It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).

The vector directed from A to B is found by subtracting its corresponding coordinates:

\overrightarrow{AB }=

\overrightarrow{AB }=

Now we express the vector as a one-column matrix as follows:

\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}

Help please when I do the guadratic equation I’m doing something wrong
AnnZ [28]

Answer:

Graph A

Step-by-step explanation

The problem: y=2x^2+8x+3

1) You will need to determine the direction of the parabola, If a > 0 then the parabola opens upward, if a < 0 then the parabola opens downward.

2) If when doing this you get an imaginary solution, you would have no x intercepts. The first thing you need to do is find the x intercepts, you can do this by plugging in 0 for y, so this would give you 0=2x^2+8x+3. Once you have this you start by subtracting 3 from both sides, dividing 8 from both side, etc. (If you would like me to elaborate don't hesitate to ask!)

3) To find the graphs y intercept you plug in 0 for x, which gives you y=2(0)^2+8(0)+3, you do the same thing you did during the previous step for y. (Once again, I am willing to elaborate further if you need!)

4) You then need to find the vertex (h,k)

To find h: h= -b/2a

To find k: k = a(h)2 + b(h) + c

5) Once you've worked through this you can graph the point!

Hope this helped!
