Answer:
Step-by-step explanation:
The graph decreases at first, then changes direction at (2, 5).
y = a(x-2)^2 + 5
Plug in (1,11) and solve for a:
11 = a(1-2)^2 + 5
a = 6
Equation in vertex form:
y = 6(x-2)^2 + 5
(2*length)+(2*width)=perimeter
length=4+2w
(2(4+2w))+(2(w))=74
74=(8+4w)+(2w)
74=6w+8
66=6w
w=11
length=4+2(11)
l=4+22
l=26

Answer:
36.98 inches each
Step-by-step explanation:
He uses 857.77 inches of fabric on headbands for 29 players and 2 coaches
29 players + 2 couches = 31 people
Inches per person = 857.77 inches / 31 people
= 27.67 inches for headbands
He also uses 269.99 inches of fabric on wristbands for just the players.
Inches per person = 269.99 inches / 29 players
= 9.31 inches for wristband
How much fabric was used on a headband and wristband for each player = 27.67 inches for headbands + 9.31 inches for wristband
= 36.98 inches each
