Question 7/10 Consider Annalee's solution on getting the sum of $ 1+4+9+16+25 $. (1) $ 1+4+9+16+25=1^{2}+2^{2}+3^{2}+4^{2}+5^{2} $ (2) $ =\sum_{k=1}^{5} k^{2} $ \[ \begin{array}{l} =\frac{6(6+1)[2(6)+1]}{6} \\ =91 \end{array} \] Did she arrive with the correct answer? Why? Choose an answer She did not since she used the incorrect formula. She did since she used the correct formula. She did since she knows how to multiply and add. She did not since she used $ n=6 $ in line (3) instead of $ n=5 $.

imagine that the roller coaster track was redesigned to include multiple hills and loops of varying heights and radii. Considering the principle of conservation of energy and the forces in the NTB coordinate system, discuss how the velocity of the roller coaster and the nurmal force would change as it moves through different points along the track. How would these changes affect the overall safety and comfort of the passengers? Considering: The relationship between the height of each hill and the velocity at the bottom. What is the equation for velocity at any point? How the radius of the loops influences the normal force at different points. What is the equation for the normal force at the top of every loop? How engineers might use this informatino to design safe yet thrilling roller coasters. What are the benefits of larger vs. smaller loops to the passenger's experience?

DATABASE 2 - Ship Company Interpret the following information related to a small database for a ship company and answer the questions that follow. Enterprise rules Rule 1: Ship information such as Ship Name, Port of Registry, Ship Builder, Building Cost, Number of Decks, Propulsion, Speed, Passenger Capacity and Number of Crew should be recorded. A ship can only operate in one region, but if it is being built or under repair it will not be linked to any region. A region can have many ships however during certain periods no ships might operate in a region. Region information include; Region Code, Location and Type Rule 2: Ships have many crew members and for a ship to sail a required number of crew members are required. Crew members can only work on one ship at a time but it may happen that they are on a recess period when they will not be working on a ship. Information such as Crew ID, Name, Surname, Date of Birth, Gender, Country of origin and Passport Number will be recorded. Instructions 1. Construct an ERD diagram from the enterprise rules above. 2. Write down the database schema entries for all entities available based on the information made available in the enterprise rules.
