Answer:
330
Step-by-step explanation:
When we are at 30 degrees on the unit circle, we are at the point (/2, 1/2) so if we go to -30 degrees (330 degrees), we will be at point (-
/2, -1/2).
Note: (cosine, sine)
We have that
F(x)=x²<span>-10x+44
</span><span>Group terms that contain the same variable
</span>f(x)=(x²-10x)+44
<span>Complete the square Remember to balance the equation
</span>f(x)=(x²-10x+25-25)+44
F(x)=x²<span>-10x+44
</span><span>Group terms that contain the same variable
</span>f(x)=(x²-10x)+44
<span>Complete the square Remember to balance the equation
</span>f(x)=(x²-10x+25-25)+44
Rewrite as perfect squares
f(x)=(x-5)²-25+44
f(x)=(x-5)²+19
this is the equation of a vertical parabola with vertex (5,19)
