Graph above^ (Giving Brainliest)In the small town of Middleton, there are only two restaurants that serve pizza- a small family owned Italian restaurant and a new franchise pizza restaurant. In a recent review of the franchise, a food critic reported that the pizza was delicious as promised. The only negative review that the franchise received from the critic was in reference to the inaccurate delivery time quoted during the order process. In response to the article, the franchise owner used a program to analyze the online pizza orders that took place during the week before the review. He chose to track the orders at 6pm each day. He recorded his results in the frequency table below.1. In two or more complete sentences, explain whether or not the franchise owner is collecting data that will be representative of the critic’s online pizza order.2. Rewrite the scenario above, with provisions to improve the outcome of the owner’s collected data. Do not alter the actual data in the frequency table.3. Analyze the new scenario, including your provisions for improvement. Do your provisions give the owner’s data the maximum possible validity? Use complete sentences to explain your answer.4. Based on the scenario and the data provided in the frequency table, what conclusion can you make with regards to the late deliveries and the promises made by the online ordering system? Use complete sentences to explain your answer.

MARKIN BRAINIEST!!! PLZ HELP!!!Over the interval (1,2),(3,4),(4,5),(2,3), the average rate of change of g is greater than the average rate of change of f.As the value of x increases, the average rates of change of f and g (remain constant decrease),(decrease and increase),(remain constant and increasing),(decrease and decrease),(increase and decrease),(increase and increase) , respectively.When the value of x is equal to 8, the value of (f(x) equals the value of g(x)),(g(x) exceeds value of f(x),(f(x) exceeds value of g(x)It can be further generalized that a quantity increasing exponentially will (always),(eventually),(never) exceed a quantity increasing linearly.

EXAMPLE 3 (a) Set up the integral for the length of the arc of the hyperbola xy = 3 from the point (1, 3) to the point 6, 1 2 . (b) Use Simpson's Rule with n = 10 to estimate the arc length. SOLUTION (a) We have y = 3 x dy dx = and so the arc length is L = 6 1 + dy dx 2 dx 1 = 6 1 + 9 x4 dx 1 = 6 x4 + 9 x2 dx 1 . (b) Using Simpson's Rule with a = 1, b = 6, n = 10, Δx = 0.5, and f(x) = , we have L = 6 1 + 9 x4 dx 1 ≈ Δx 3 [f(1) + 4f(1.5) + 2f(2) + 4f(2.5) + ⋯ + 2f(5) + 4f(5.5) + f(6)] ≈ (rounded to four decimal places).
