A 2007 article on identify theft included the statement: “Electronic payments boosted the Canadian economy by 25 per cent over the past two decades, representing $107 billion of the economy’s $437-billion growth from 1983 to 2003, according to a study sponsored by Visa Canada in 2004.” Identify and explain three items of concern that would be part of a critical analysis. (HINT: You must use 3 categories from critical analysis. Categories include; sample, author, source, relevance, bias)

-6 is the correct option from the above given options

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
