Question 1038807
.
For what value of 'A' will Avē-144=0 have one solution between 3 and 4 and the other solution is between -4 and -3?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
{{{Av^2-144}}} = {{{0}}} is equivalent to {{{v^2}}} = {{{144/A}}}.


Therefore, to satisfy your condition, A must satisfy an inequality 


{{{3^2}}} <= {{{144/A}}} <= {{{4^2}}},  or, which is the same, 


{{{9}}} <= {{{A}}} <= {{{16}}}.

<U>Answer</U>.  {{{9}}} <= {{{A}}} <= {{{16}}}.
