Response to TV Advertising

[greatwhiteshark]

The percent R of viewers who respond to a TV commercial for a new product after t days is found by using the following formula:

R = 70 - 70e^-0.2t.

What is the highest percent of people expected to respond?

Can you draw the graph?
Do you know anything about exponentials?
What happens as t increases?
What happens as t decreases to zero (0)?
Should we consider values for t < 0?

hey

Please, stop answering my questions. I can read very well through e-mails. You appear to be a very proud person. I suppose you can answer every math question every written??????

Does that mean you are not going to answer my questions?

Janet:
this can be answered starting at square 1, assuming you want a FULL
solution including explanations of "e" and "t" and how to apply symbol "^",
thus whoever answers having to type pages of stuff...

Or we can ASK (as Mr Hunny did) a few questions to get an idea
of what it is you do not understand, thus making the tutor's work
more reasonable.

I'm staying out of the "argument" (though I'm strongly tempted otherwise);
AND I sure hope Mr Soroban ALSO gives his opinion...

yes

A much better reply from Denis.
