y = -16x² + 32x
y = -16(x² - 2x)
y = -16(x² - 2(x)(1) + 1² - 1²)
y = -16(x - 1)² + 16
Max height is when (x-1) = 0
So x = 1

Answer:
26 1-foot squares of silver paper.
Step-by-step explanation:
The dimensions of the bulletin board are 6.5 feet by 4 feet.
To determine how many squares of silver paper she needs to but, we first determine the area of the bulletin board.
Area of the board =6.5 X 4= 26 Square feet
Therefore, Mrs Golden needs to buy <u>26 1-foot squares of silver paper.</u>
There will be <u>no pieces left over</u> as there is no decimal or fractional value in the area of the bulletin board.
