Consider a<span> right triangle with </span><span>hypotenuse of 1.
sin x means to divide the side in front of the angle by </span>hypotenuse<span>
cos x means to divide the side beside the angle by hypotenuse
we know that a^2+b^2=c^2 now divide two sides by c^2

c is 1 also a/c means sinx and b/c is cos x so
sin^2(x)+cos^2(x)=1
</span>
Answer:
-1
Step-by-step explanation:
First we combine like terms, so y2 - 5y = - 3y
Now we get - 3y = 3
Then we divide both sides by - 3
Now we get y =-1
The answer is B. 8/9 •4/3
5 beads are used for every 3 inches, that makes 5/3 beads per inch.
Thus that can be modeled by the graph y=x*5/3 where x is the number of inches and y is the number of beads.
