A) Show that the equation x3 + 6x - 5 = 0 has a solution between x = 0 and x = 1 b) Show that the equation x3 + 6x – 5 = 0 can be arranged to give x =
5
X2 + 6
by filling in the boxes. x3 + 6x -5 = 0
x3 + 6x =
X =
(x2 + 6) =
5
x2 + 6
c) Starting with x = 0, use the iteration formula xt1 =
5
X,2 + 6
twice,
to find an estimate for the solution of x3 + 6x - 5 = 0

Questions 9-10. use the table of educational expenditures to answer the questions. k-12 education expenditures population indiana $9.97 billion 6.6 million illinois $28.54 billion 12.9 million kentucky $6.58 billion 4.4 million michigan $16.85 billion 9.9 million ohio $20.23 billion 11.6million 9. if the amount of k-12 education expenses in indiana were proportional to those in ohio, what would have been the expected value of k-12 expenditures in indiana? (give the answer in billions rounded to the nearest hundredth) 10. use the value of k-12 education expenditures in michigan as a proportion of the population in michigan to estimate what the value of k-12 education expenses would be in illinois. a) find the expected value of k-12 expenditures in illinois if illinois were proportional to michigan. (give the answer in billions rounded to the nearest hundredth) b) how does this compare to the actual value for k-12 expenditures in illinois? (lower, higher, same? )
