• How many 5 inch pieces of wood can
you cut* from a board that is 4 feet
long

9

Step-by-step explanation:

To find the answer, first convert 4 ft. to inches. 4 ft.= 48 in. Now, you divide 48÷5. 48÷5=9 3/5, or 9.6, but you can't cut a sixth of a board. Therefore, the answer is 9.

Hope this helps!

9 pieces

Step-by-step explanation:

First, convert 4 feet to inches. 4 ft = 48 in.

Then, divide 48 in by 5 in. 48/5 is 9.6 in

But since you can't cut the board into sixths the answer is 9.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
