Answer 2

d.
`\left[\begin{array}{ccc}x+3\\y+4\end{array}\right]`

Explanation:

We are given that the wind blew the ball so that it landed approximately 3 feet east and 4 feet north of where it was thrown into the air.

We know that East is at the right which can be shown by positive value of x while North is upwards so it can be shown by addition in the value of y.

Therefore, the correct answer option is:

d.
`\left[\begin{array}{ccc}x+3\\y+4\end{array}\right]`
