Answer:
f(x)=(x-3)^2-7
Step-by-step explanation:
Vertex form: f(x) = a(x-h)^2+k
x^2-6x+9+2=f(x)+9
(x-3)^2+2=f(x)+9
f(x)=(x-3)^2-7
The estimated number of ramps that can be cut from the board in discuss is; 6 ramps which is a reasonable assumption provided that each ramp is about 2 feet long.
b). The number of ramps that can be cut from the 12 1/2 feet long board is 6 and hence, the length of wood left is; 1/2.
<h3>What is the number of ramps that can be cut from the 12 1/2 feet long board?</h3>
It follows from the task content that skateboard ramps are made from a 12 1/2 feet long ramp.
Consequently, on the assumption that the quantity by measure of length of the board required to make one skateboard ramp is 2 feet, it follows that the estimated number of ramps that can be made from the board is; 12/2 = 6 skateboard ramps.
Ultimately, the amount of wood which is left over upon making the ramps is; 12 1/2 - 12 = 1/2.
