question 51

Essay

A mathematical model can approximate the winning distance for the Olympic discus throw by the formula d = 175 + 1.75t,where d is in feet and t = 0 corresponds to the year 1948.We might want to predict in what year a certain distance will be exceeded,so rewrite the equation to solve for t.Use a graphing calculator to graph the resulting equation and find the coordinates of any two points on the line and use them to estimate the slope.Compare this with your answer.
