Answer:
cos theta=4/5
b/h=4/5
b=4 and h=5
p=?
H^2=P^2+B^2
5^2=P^2+4^2
25-16=P^2
9=P^2
=P
3=P
Now,
sin2theta
=p/h2
=3/5*2
=9/5
Step-by-step explanation:
$36.12 is the better deal. The reason why is because if you divide $17.59 by 4 and then divide $36.12 by 9, you will find that the cost per shirt is cheaper for option two. Also if you multiply $17.59 by 2 you will find that for eight shirts it's $35.18, so just for a dollar more you get one more.
So for the first one it is (x-3)(x+3) this is because it is a difference of squares so you square root the 9 and the minus you do both +and - in order to keep up the -9
The zeros are:x=3 and x=-3 ( this is because you change the sign in the bracket
the others should be pretty simple to do for number 2 its a complex
the third is a simple trinomial
and fourth is simple trinomial as well
