Question

$open parentheses 2 x y squared plus 3 x minus 4 close parentheses plus open parentheses 3 x y squared minus 8 x plus 4 close parentheses$
Which of the following is equivalent to the expression above?

$5 x y^{2} - 5 x$
$5 x y^{2} + 5 x$
$5 x y^{2} - 5 x - 8$
$5 x y^{2} + 5 x + 8$

The correct answer is: $5 x y squared minus 5 x$

$text Given, end text open parentheses 2 x y squared plus 3 x minus 4 close parentheses plus open parentheses 3 x y squared minus 8 x plus 4 close parentheses equals left parenthesis 2 plus 3 right parenthesis x y squared plus left parenthesis 3 minus 8 right parenthesis x plus 4 minus 4$
$equals 5 x y squared minus 5 x$

There were no jackrabbits in Australia before 1788 when 24 jackrabbits were introduced. By 1920, the population of jackrabbits had reached 10 billion. If the population had grown exponentially, this would correspond to a 16.2% increase, on average, in population each year. Which of the following functions best models the population p(t) of jackrabbits t years after 1788?
