Chapter 1, Problem 83RE
Solve each equation in Exercises 73-81 by the method of your choice.
One possible reason for the explosion of college tuition involves the decrease in government aid per student. In 2001, higher-education revenues per student averaged $8500. The bar graph shows government aid per U.S. college student from 2005 through 2012. (All figures are adjusted for inflation and expressed in 2012 dollars.)
Source: State Higher Education Executive Others Association
The mathematical model
Describes government aid per college student, G, x years after 2005.
a. Does the model underestimate or overestimate aid per student in 2011? By how much?
b. If we project the model past 2012, determine in which year government aid per student decreased to $4127.

Every projective module is a free module. a homomorp cements Q.4) Give an example and explain your claim in each case: a) A module M which has a largest proper submodule, is directly indecomposable. b) A free subset of a module. c) A finite free module. d) A module contains no a direct summand. e) A short split exact sequence of modules.arrow_forwardListen ANALYZING RELATIONSHIPS Describe the x-values for which (a) f is increasing or decreasing, (b) f(x) > 0 and (c) f(x) <0. y Af -2 1 2 4x a.
