Answer:
0
Step-by-step explanation:
f(x) = √(x) + 12
g(x) = 2√(x)
(f-g)(x) = √(x) + 12 - 2√(x)
(f-g)(x) = 12 - √(x)
if x = 144
(f-g)(144) = 12 - √(144) = 12 - 12 = 0
First we need to know the total area. Since this is a rectangle we need two adjacent sides and we can find these from vertex pairing:
Matching y: (3,9) --> (5,9) = 2 ft
Matching x: (3,9) --> (3,3) = 6 ft
Area = l*w = 2*6 = 12 square ft
# of bags = 12sqft/(5sqft/bag) = 2.4 bags.
Cost = $5.00 * 2.4 = $12 (notice that it cost $1 to cover 1sqft so we could have skipped a step here.)
NOTE: In the real world she probably can't buy just 0.4 of a bag and would actually have to buy three full bags for $15.
