Answer:
Step-by-step explanation:
Alright, lets get started.
Tomas has four pieces of wood having each length = 5, 4, 6 and 3
The length of wood he needs to cut to make a model airplane = 
Simplifying, it is 3.32 feet long
Means he needs more than 3 feet but less than 4 feet of wood piece.
So, he should select 4 feet length of wood because selcting 3 feet will not fulfilled to make his model and selcting 5 and 6 feet will have more unused wood.
4 feet piece of wood he should cut to have the least amount of unused wood. : Answer
Hope it will help :)
Use our brains and what we know
f(x)=a(x-h)²+k
vetex is (h,k)
and a is te leading coefient
if directix is below the focus, then it opens up and a is positive
if directix is above focus, then it opens down and a is negaitve
vertex is in between directix and focus
so
(3,-1) and y=1
-1<1
so directix is above
a is negative
directly in between
distance from -1 to 1 is 2
2/2=1
1 above (3,-1) is (3,0)
vertex is (3,0)
y=a(x-3)²+0
y=a(x-3)²
the only option with a negative 'a' value is B
answer is B
