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:
The value of this inheritance is $78,192.28
Step-by-step explanation:
The monthly payments Sara will receive starting today for next 40 years is $500.
Annual Interest Rate = 7.3%
Monthly Interest Rate = Annual Interest Rate/12
=7.3/12
Monthly Interest Rate = 0.6083%
Present Value = $500 + $500/1.006083 + $500/1.006083^2 + $500/1.006083^3 + ... + $500/1.006083^479
Present Value = $500 * 1.006083 * (1 - (1/1.006083)^480) / 0.006083
Present Value = $500 * 156.39156
Present Value = $78,192.28
Thus, the value of this inheritance is $78,192.28
Answer:
Suzie walks faster by 0.27 miles per hour.
Step-by-step explanation:
Addie walked
miles in 45 minutes and Suzie covered
miles in
of an hour.
So, Addie walked 2.5 miles in 45 minutes i.e.
hours.
Therefore, the walking speed of Addie is
miles per hour.
Again, Suzie covered
i.e. 2.4 miles in
i.e. 0.67 hours.
So, the walking speed of Suzie is
miles per hour.
Hence, Suzie walks faster by (3.6 - 3.33) = 0.27 miles per hour. (Answer)
Neither are correct.
Navene has broken the problem up and simply added numbers together to get "4577"
Annabelle is also wrong because whereas she multiplied, she also broke up the numbers in the equation to get "46710"
The answer should be 18,690,300
