Answer:
The correct answer is A
Step-by-step explanation:
The books sold are 30,000, so that is our total sale for January. His sales are <em>decreasing</em> by an average of 500 books <em>per month</em>, which means he is losing sales so it is a negative value, and we multiply that by <em>x</em> (number of months) since the question has not stated the number of months. Therefore, the equation would be f(x) = 30,000 - 500x
Hope this is of help!
Tell me which one they are too many
You have to use the fact that 
for any value of 
. So
where 
is the positive acute angle you're looking for.
<span>f(x)=x^2+6x+3
=(1/2.6)^2=3^2=9
f(x)=(x2^+6x+9)+3-9
=(x+3)^2-6</span>
