Answer:
Recycling
Step-by-step explanation:
because i see recyling bins everywhere
We have that
<span>sin x=2/9
we know that
sin</span>² x+cos² x=1---------> cos² x=1-sin² x-----> cos² x=1-(2/9)²
cos² x=1-(4/81)------> (81-4)/81-----> 77/81
cos x=√(77/81)
Sin 2x = 2 sin x cos x-------> 2*(2/9)*(√(77/81))----> (4/81)*√77---> 0.43
Sin 2x=0.43
so
cos² 2x=1-sin² 2x---------> 1-[0.43]²-----> 1-[0.1878]----> 0.81
cos² 2x=0.81-----------> cos 2x=0.9
tan 2x=sin 2x/cos 2x--------> tan 2x=0.43/0.9---------> tan 2x=0.48
the answers are
sin 2x=0.43
cos 2x=0.9
tan 2x=0.48
Answer:
2.68 pints
Step-by-step explanation:
The fraction of white paint is 1 -3/5 = 2/5, so the quantity of white paint is ...
(2/5)(6.7 pints) = 2.68 pints
Kimberly used 2.68 pints of white paint.
Answer:
so the lowest term is 1/10
