Let C be an n × n consumption matrix whose column sums are less than 1. Let x be the production vector that satisfies a final demand d , and let Δ x be a production vector that satisfies a different final demand Δ d .

a. Show that if the final demand changes from d to d + Δ d , then the new production level must be x + Δ x. Thus Δ x gives the amounts by which production must change in order to accommodate the change Δ d in demand.

b. Let Δd be the vector in Rn with 1 as the first entry and 0’s elsewhere. Explain why the corresponding production Δx is the first column of (I – C)–1. This shows that the first column of (I – C)–1 gives the amounts the various sectors must produce to satisfy an increase of 1 unit in the final demand for output from sector 1.

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
