Answer:
They need 2 and 1/2 rolls.
Step-by-step explanation:
Area = length x width
A = l x w
A = 20 x 3
A = 60 ft²
If 60 ft² = 1 roll
What about 150 ft² = ?
= (150 x 1) ÷ 60
= 150 ÷ 60
= 2.5
= 2 and 1/2 rolls
We need to know the function that models the difference in the number of customers visiting the two stores.
We know the function that models the number of customers in the cafeteria
W (x) = 0.002x3 - 0.01x2
We also know the function that models the number of customers who visit the ice cream parlor
R (x) = x2 - 4x + 13
Therefore the difference, D (x), in the number of customers visiting the two stores is:
D (x) = W (x) - R (x)
D (x) = 0.002x ^ 3 - 0.01x ^ 2 - (x ^ 2 -4x +13)
D (x) = 0.002x ^ 3 - 0.01x ^ 2 - x ^ 2 + 4x -13
D (x) = 0.002x ^ 3 - 1.01x ^ 2 + 4x -13

Answer:
Step-by-step explanation:
domain X is real number
range Y larger or equal to -3 (cause 4x^2 is always >= 0)
