Write a for loop that calculates the first 35 numbers of the Fibonacci Sequence. The Fibonacci Sequence is a famous sequence, where the value of each number in the list is the sum of the two before it. The first 5 numbers in the Fibonacci Sequence are 0, 1, 1, 2, and 3. As such, any value in element $n$ of the sequence, is the sum of element $n-1$ and element $n-2$. Create a row vector named \texttt{fib} that contains the sequence of numbers. Hint: You might want to start your loop at the 3rd element in \texttt{fib}. For the Fibonacci to work, you must know the first 2 digits in the sequence ahead of time. DO NOT just fill your vector in manually by figuring out the sequence and manually the array. You MUST use a loop in order to do this.

Problem 3: Ammonia and Oxygen react as follows. $NH_3 + \beta_1O_2 \to \beta_2NO_2 + \beta_3H_2O$ (a) You are required to determine the stoichiometry$\{\beta_1, \beta_2, \beta_3\}$ by doing atomic balances and writing this as a linear system of equations $A\beta = b$, where A = 3 × 3 matrix; b = 3 × 1, and $\beta$ = 3 × 1 (unknowns). Show details of your system of equations. (b) Solve the system by hand using Gaussian Elimination. [Hint: to do an atomic balance on an atom say N, you need to count the number of N atoms on both sides of the chemical reaction.]

1. A delivery company is considering adding another vehicle to its delivery fleet, all the vehicles of which are rented for $100 per day. Assume that the additional vehicle would be capable of delivering 1500 packages per day and that each package that is delivered brings in ten cents ($0.10) in revenue. Also assume that adding the delivery vehicle would not affect any other costs. a. What is the MRP? What is the MRC? Should the firm add this delivery vehicle? b. Now suppose that the cost of renting a vehicle doubles to $200 per day. What are the MRP and MRC? Should the firm add a delivery vehicle under these circumstances? c. Next suppose that the cost of renting a vehicle falls back down to $100 per day but, due to extremely congested freeways, an additional vehicle would only be able to deliver 750 packages per day. What are the MRP and MRC in this situation? Would adding a vehicle under these circumstances increase the firm's profits?
