The calculator function that puts the augmented matrix
![\left[\begin{array}{cc|c}2&4&8\\6&3&-3\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D2%264%268%5C%5C6%263%26-3%5Cend%7Barray%7D%5Cright%5D%20%20)
into reduced row-echelon form will give you an identity matrix in the left columns and the solution in the rightmost column:
![\left[\begin{array}{ccc}1&0&-2\\0&1&3\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%26-2%5C%5C0%261%263%5Cend%7Barray%7D%5Cright%5D%20%20)
This corresponds to the first selection.
Answer: .08
Step-by-step explanation: To write 8% as a decimal, we move the decimal point 2 places to the left. Filling in the missing position with a 0, we have .08.
Notice that 8% translates to the decimal .08 <u><em>not</em></u> <em>.</em>8.
Watch out for this common mistake.
Answer:
w = 25
Step-by-step explanation:
The function A(w) = -(w-25)² +625 is in vertex form. The vertex (maximum) is at (w, A) = (25, 625). A width of 25 meters will maximize the area.
