The number A of tablet
complrters sold (in millions) can be modeled by the
functionA : 4.5t2 + 43.5t * 17, where /represents
the year after 2010.
A . In what year did the tablet computer sales reach
65 million?
B . F'ind the average rate of change from 2010 to 2012 and interpret the meaning in the context of
the situation.
C . Do you think this model will be accurate after a new, innovative computer is developed? Explain.

Best ResponseYou've already chosen the best response.1So you want to know when A=65 solve the equation 65=4.5t^2+43.5t*17 (if that is the right equation; kind of wonder if you meant to put +17 at then end instead of *17)

Best ResponseYou've already chosen the best response.1for B evaluate: \[\frac{f(2)f(0)}{20} \\ \text{ since } t=2 \text{ actually means 2 years after 2010 which is the year 2012}\\ \text{ and since } t=0 \text{ means the year 2010}\]

Best ResponseYou've already chosen the best response.0I substitute a = 65 I solve t=1 Then 1+ 2010 = 2011 ?

Best ResponseYou've already chosen the best response.1right I don't think they care about what happened before 2010... you know because you do get also t=10.6667 as a solution

Best ResponseYou've already chosen the best response.1which I would take that to mean like little more 10 years before but like I said I don't think they care about what happens before

Best ResponseYou've already chosen the best response.1sorry evaluate: \[\frac{A(2)A(0)}{20}\] there does that make more sense ?

Best ResponseYou've already chosen the best response.1That is the average rate of change of A from the year 2010 to 2012 (aka t=0 to t=2)

Best ResponseYou've already chosen the best response.1C) I don't know...The economy is always changing...But I think they are making computers cheaper... There will be more people. Some people will be fine with their old computer and won't think it necessary to purchase another computer.

Best ResponseYou've already chosen the best response.1For example I don't even know if the function they gave is a great model currently for any computer type available without doing any research.
