Answer:
4/5
Step-by-step explanation:
that is it
We know that sin2x=2sinxcosx
(search the net for proof if you wish)
So the original equation becomes
2sinxcosx-sinx=0
The two terms both have sinx that can be taken out to get:
sinx(2cosx-1)=0
This is true if sinx=0 or 2cosx-1=0 , rewritten: cosx=1/2
sinx=0 than x=2kπ
cosx=1/2 than x=π/3+2kπ
where k is an integer
Answer:
<em>Net price: $4972.50</em>
Step-by-step explanation:
<u>Percentages</u>
We know a ream of paper has a list price of $25.50. Custom Greetings placed an order for 300 of them. If they have purchased them at list price, the total price would have been
300*25.50=$7,650
But we also know there was a 35% trade discount, so the net price of their order is
$7,650-$7,650*35/100=$4972.50
The answer is 52+7x I hope this helps
