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
<span> The answer is the third option</span>
7x+70=98
7x=28
x=4
this is the answer

Answer: n=2
Step-by-step explanation: 4n-2n=4
4(2)-2(2)=
8-4=4
To find out the cyclist's average speed you simply have to divide 50.0km
by 2.5 to find the answer. Therefore the cyclist's average speed is
20.0 km an hour.
