Rational Function: The heat, H, in BTUs, created by an industrial furnace can be modeled by the equation H = kx/(100-x), where k is a constant and x is the percent of oxygen in the air that is going into the furnace. 1. When there is 70 percent oxygen in the air, then 350,000 BTUs of heat are created. Find the value of k in the model. I think the answer is K=2,4627.27. Is that correct? 2. Use the model to determine the percent of oxygen in the air if the furnace creates 780,000 BTUs of heat. Round you answer to two decimal places.

Exercise: Newton's Divided Difference Method (a) Construct a divided difference table from the following data: 0 0.3 0.6 1.8221 3.3201 0.9 6.0496 1.2 11.0232 f(x) (b) Use the table presented in Question (a) along with Newton's Divided Difference Formula to approximate f (0.1) with a polynomial of degree three. Start with x = 0. Estimate the error in the approximation. (c) Use the table presented in Question (a) along with Newton's Divided Difference Formula to approximate f(1.1) with a polynomial of degree three. Start with x4 = 1.2. Estimate the error in the approximation. (Hint: Read the divided difference table from the "downside up".)
